Counting words in a string??

[Jake]

Hi, I need a program which:
1) Asks the user for a sentence of their choice (not including punctuation)
2) Ask the user which word they would like to know is repeated
3) Print out to the user how many times the word came up which they chose from 
their sentence.

It would help if you could comment the code. 
Thankyou in advance!!

\r functionality

[Jake]

in c and c++ there is a useful way to refresh an output line in printf
and cout using \r meta command. So for example in the wget application
the progress of the download is updated on the same output line of the
screen. From an intital investigation python seems to lack this. Is
this correct?

Hi!  I come from a mvc framework background in a few different
languages (java, php, ruby).  I'm only a couple weeks into web2py, I'm
finding web2py a joy to work with.  I won't waste your time with the
features it provides, as you can find these on the website.  There is
also a copy of the lead developer's book on the site, and its very
well written.

If web2py intrigues you, I would recommend just trying it for a few
days.  It's pretty small (relatively few exposed classes and
functions) and very comprehensible, so you won't really have to invest
much if you decide to try it and don't like it.  The mailing list is
active and responsive, and the lead developer happens to have chimed
in on every question i've asked.  On the down side, the irc community
is very small.

Good Luck,
Jake

Re: Average calculation Program *need help*

[Jake Kobs]

Thank you for the help..I think I'm getting closer, but I feel like after they 
enter an invalid number, it should reset the invalid number(s) somehow. Here's 
my updated code:
--
#this function will get the total scores
def getScores(totalScores, number):
for counter in range(0, number):
score = input('Enter their score: ')
if (score < 100 and score > 0):
totalScores = totalScores + score
while (score > 100 or score < 0):

print "Your scores must be between 0 and 100."
score = input('Enter their score: ')
score = input('Enter their score: ')
totalScores = totalScores + score 


return totalScores

Hi Cool,

Unfortunately you really gotta know enough Python to put things together,
so if you have time - learn a little more python, and then you can choose
any of these 2 tools to do the job:
http://doc.scrapy.org/en/latest/intro/tutorial.html
http://www.gregreda.com/2013/03/03/web-scraping-101-with-python/

In fact i agree you dont even need python.  Even Bash / shell script with
wget can do this.

However if you dont have the time or dont want to exert the req'd effort,
unfortunately this list is not for giving free code.
I suggest you hire somebody at odesk.com or elance.com - you'd be amazed
how low people there charge for python "web scraping".

Good luck!

Python variable as a string

[Jake Angulo]

Sorry this is a very basic question.

I have a list *var* which after some evaluation I need to refer to *var* as
a string.

Pseudocode:

var = ['a', 'b' , 'c' , 'd']
adict = dict(var='string', anothervar='anotherstring')
anotherdict = dict()
if :
anotherdict[akey] = adict['var']


Basically im evaluating the list *var*, and if true, i want to use *var* as
a string so that i can refer to a key-value pair in *adict *(whose key name
is also var for convenience).
*
*
Or maybe i should do things differently?

Any help and code will be appreciated!

Re: Python variable as a string

[Jake Angulo]

Thank you all for the reply.

Actually yes this was a confusing question, and borne out of trying to make
a shortcut.
I didnt ask to convert the contents of var into a string.
All I needed was to get the literal equivalent "var" because I needed to
use it in another dict object - whose keys i named the same (eg 'var') for
convenience.  Instead i ended up complicating stuff.

I resolved this by doing things differently with (if - elif - else).

Sorry for the confusion - but thanks all for answering - i can use a code
or two of what you have shared!

Re: Tryign to send mail via a python script by using the local MTA

[Jake Angulo]

Up Robert Kern's reply!

I was waiting for smtplib  to be
mentioned... finally!  Instead people simply answer philosophically.  I
dont want to judge whether OP is a troll or not - but i found a lot of
arrogant replies here.  I have also worked on an antispam project before,
and see through the intents of the OP, but I do not pretend to be a
moralist. I was hoping we would strictly discuss code or software
architecture here, not morality. Simple question, simple answer pls, in the
interest of the Python list.

To the OP:

You might want to google smtplib, and use that instead of os calling a
system command. Smtplib takes care of all the operating system's quirks for
you, and still uses the os native sendmail program.

On the other hand, the way you are sending email is highly suspect, trying
to spoof a domain, random email address, etc.  It is not easy to fool most
modern email servers nowadays - especially gmail's.  They verify first that
the sending domain matches the IP of the sender.  And if you are trying to
do this - it is neither Python's nor the OS fault.

Happy coding!

Twisted or Tornado?

[Jake Angulo]

I have to say it first: I am not trolling :P

Im working on a server project (with IOS client) and would like to create a 
custom, lean and mean server - real Quick!

My requirements for this framework in descending order:
1) Easy to use API
2) Widely available documentation / Examples / Community contributions
3) Feature-wise - kinda most that you commonly need is there

Your opinions will be valuable, if possible cite examples or URL references, 
Pls!  

I prefer opinion from those who have programmed real projects in it - not just 
read some blog or Slashdot :P

Re: Twisted or Tornado?

[Jake Angulo]

All,

Thanks for your reply - I thought I would share the outcome of my choice:

I have chosen to use twisted.   The API is very decent to learn, though the
clincher is theres huge community / docs, and many projects used on
production.

I was able to make a working project prototype in hours!
Thanks to the large twisted library.

Our project is an ipad multiplayer game, and we didnt want to use existing
servers because we want to do things exactly as we wish.

Rgds,

Jake

Re: Do you feel bad because of the Python docs?

[Jake Angulo]

The OP speaks for himself alone.

Python - for such a very young language, and with the documentation and
community blogs available at this point - I cannot ask for more.

And who needs docs when the python syntax is as good as writing plain
english sentence?

im.py: a python communications tool

[Jake D]

Hey Usenetites!
I have a horrible Python program to allow two people to chat with each
other.  It has horribly any functionality, but it is meant for the
public to work on, not necessarily me.  Anyways, here's a quick FAQ.

What does this do that IRC can't?  What does this do that AIM can't?
--It allows direct communication between two computers, whereas IRC
doesn't.  And AIM and similar services require a username, etc.  This
is made specifically for two users on a network to chat.
What version of Python is this written in?
--Python 2.7.3.
What is the licence?
--It's released under a special FOSS licence.  Here it is:
You can do whatever you want with this program.

Alright, now, here's the code:

#!/usr/bin/python
#An instant messaging program implemented in Python.
#Created on Sunday, December 30, 2012 (long before it's Usenet
publication)

import socket
import sys
import threading

def server_listen():
while True:
r = c.recv(8192)

if r == "\quit":
c.close()
s.close()
sys.exit(0)

print con_addr[0], ": " + r

def client_listen():
while True:
r = s.recv(8192)

if r == "\quit":
s.close()
sys.exit(0)

print sys.argv[1], ": " + r

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

if sys.argv[1] == "-l":
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind(('', 5067))
s.listen(5)
c, con_addr = s.accept()

while True:
r = c.recv(8192)

if r == "\quit":
c.close()
s.close()
sys.exit(0)

print con_addr[0], ": " + r
i = raw_input("You: ")

if i == "\quit":
c.send("\quit")
c.close()
s.close()
sys.exit(0)

c.send(i)

else:
s.connect((socket.gethostbyname(sys.argv[1]), 5067))
print "Chat initiated with " + sys.argv[1] + "!"

while True:
i = raw_input("You: ")

if i == "\quit":
s.send("\quit")
s.close()
sys.exit(0)

s.send(i)
r = s.recv(8192)

if r == "\quit":
s.close()
sys.exit(0)

print sys.argv[1] + ": " + r

I encourage people to modify this code, because really, it sucks.

nested dictionary assignment goes too far

[Jake Emerson]

I'm attempting to build a process that helps me to evaluate the
performance of weather stations. The script below operates on an MS
Access database, brings back some data, and then loops through to pull
out statistics. One such stat is the frequency of reports from the
stations ('char_freq'). I have a collection of methods that operate on
the data to return the 'char_freq' and this works great. However, when
the process goes to insert the unique 'char_freq' into a nested
dictionary the value gets put into ALL of the sub-keys for all of the
weather stations. I have isolated (I think) the problem to the compound
key assignment in the next-to-last line before the print statements.
The result is that the last 'freq' to run throught the for loops gets
posted to all of the sensor_numbers.  Eventually the process will put
in stats for the other keys in the nested dictionary, so that's why I
have set up the dictionary this way.

Thanks in advance!

run_flag=1
if run_flag > 0:

   distinctID = runSQL(Unique_IDs)
   distinctID = map(firstpart,distinctID) # converts the list of tuples
that is returned to a list of numbers
   rain_raw_dict =
dict.fromkeys(distinctID,{'N':-6999,'char_freq':-6999,'tip1':-6999,'tip2':-6999,'tip3':-6999,'tip4':-6999,'tip5':-6999,'tip6':-6999,'lost_rain':-6999})

   rawList = runSQL(Rain_Raw_Count)

   temp_list = [110,140,650,1440]

   for sensor_count, sensor_number in enumerate(temp_list):
  # get the frequency of timer reports for each rain gauge
  # note that when a for loop is of the form "for X, x in
enumerate(xList)",
  # X is an index value, and x is the value itself.
  timerList = []
  for icount, i in enumerate(rawList):
 if i[0]==sensor_number:
for jcount in range(icount+1,len(rawList)): # look ahead to
the next values for comparison
   if rawList[jcount][0]==sensor_number:
  if rawList[icount][2]==rawList[jcount][2]:
 temp = rawList[jcount][1]-rawList[icount][1]
 timerList.append(temp)
 icount = jcount-1
 break

  # now build a histogram of the time differences stored in
"timerList"
  h = Histogram()
  timer = h.histo(timerList)
  sorted_timer = h.sorted_histo(timer)
  freq = h.characteristic_freq(sorted_timer)
  rain_raw_dict[sensor_number]['char_freq'] = sensor_number   #
 here's the problem!!
  freq = -6999

print "ID = 110:",rain_raw_dict[110]
print "ID = 140:",rain_raw_dict[140]
print "ID = 650:",rain_raw_dict[650]

Re: first book about python

[Jake Emerson]

There have been lots of recommendations for the O'Reilly book, which is
a good one. However, I would recommend "Beginning Python" by Magnus Lie
Hetland. All I knew before starting Python was Mathematica, and this
book was very helpful. It may seem to start out slow, but I've found
that I'm going back to those first chapters occasionally to review and
practice the syntax. It, and this group, have carried me through some
pretty tough problems (for me anyway). It's been worth it. Good luck.

Clearly the browser is in the path, because it opens.  It just fails to open

I just tested this in both Windows (Vista) and Linux (Kubuntu 7.10 and
Slackware 12) without any problems.  Try it from the interpreter; if it's
actually executing successfully, you should see something that looks like
this:

>>> import webbrowser
>>> webbrowser.open("file:///home/user/path/to/file/test.html")
True
>>>

A couple ones have been submitted. Harald gets a point about the 
redundant tests (even if his solution seems to be broken, cf below) - 
your inner loop should have looked like :


  for j in xrange(i+1, len(IN))

Now the obvious winner is pruebono - even unoptimized, using sets seems 
to be *way* faster than even the most optimized corrected version of 
your algorithm.


Here's a quick bench - please everyone doublecheck it to make sure it's ok:




Results here (py2.5, gentoo linux, athlonxp1800, 512 ram):

Not surprisingly, half less iterations makes for half less time. 
Aliasing, as often, proves to be a good optimization too. But obviously, 
using the correct data structure / algorithm combo is the key : simpler 
code, and 115 times faster (143 times with aliasing). If pruebono 
solution's is correct (and it as AFAICT), your 15 hours computation

Efficient python 2-d arrays?

[Jake Biesinger]

Hi all,

Using numpy, I can create large 2-dimensional arrays quite easily.
>>> import numpy
>>> mylist = numpy.zeros((1,2), dtype=numpy.int32)

Unfortunately, my target audience may not have numpy so I'd prefer not to use 
it.

Similarly, a list-of-tuples using standard python syntax.
>>> mylist = [(0,0) for i in xrange(1)

but this method uses way too much memory (>4GB for 100 million items, compared 
to 1.5GB for numpy method).

Since I want to keep the two elements together during a sort, I *can't* use 
array.array.
>>> mylist = [array.array('i',xrange(1)), 
>>> array.array('i',xrange(1))]

If I knew the size in advance, I could use ctypes arrays.
>>> from ctypes import *
>>> class myStruct(Structure):
>>> _fields_ = [('x',c_int),('y',c_int)]
>>> mylist_type = myStruct * 1
>>> mylist = mylist_type()

but I don't know that size (and it can vary between 1 million-200 million), so 
preallocating doesn't seem to be an option.

Is there a python standard library way of creating *efficient* 2-dimensional 
lists/arrays, still allowing me to sort and append?

Thanks!

Yes, this is an option. Writing a custom sort function just didn't sound very

It's a good suggestion, though I am far from familiar with the process.

I've just finished implementing another alternative-- I'm doing a merge sort, 
where the array chunks are zipped together and then sorted using python's 
builtin sort then unzipped back to their original arrays. This seems fast 
enough and the reduced memory requirement for 2 arrays vs 1 list-of-tuples is 
substantial (1.5 GB vs 4GB).

Thanks for the great suggestions!

My users are biologists, and I can't expect them to have numpy (and the barrier 
to entry for this group is particularly high).

On a related note, is there no way to efficiently sort a python array?


>>> x = array('f', xrange(1000))
>>> x.sort()
---
AttributeErrorTraceback (most recent call last)

/home/wbiesing/src/python-sort/ in ()

AttributeError: 'array.array' object has no attribute 'sort'

>>> type(sorted(x))


Seems like a common enough task, but no way to do it efficiently without 
scipy/numpy.

Re: parsing XML

[Jake b]

Check out Amara: http://www.xml3k.org/Amara/QuickRef

It looks promising. For a pythonic solution over sax / dom.

>>> Iter(doc.team.player)
# or
>>> doc.team.player[0].name

[ new to the list, so I'm not sure why my previous response failed. Is
it on me? Because using iPod, vs thunderbird?

However, looking at superpollo, the reply-to didn't include
python-list. Or even a valid address ?

Message below. Ty.

View Html/ py code in a zip as HTML/text ? ( for phone )

[Jake b]

I'm trying to figure out the best way to view python snippets /
smaller files on the itouch/iPhone.
I'm reading a new projects docs, but it's not easy to view the zip.

It can't view zip files. Say I want to read pyglet examples, I need
unzip at least one file and serve that. If it is text/HTML/py , then
view in pastebin.

Is there a trick to do this? Or maybe for certain sites. I thought I
had seen a way google did it to a zip not hosted on google code, but
can't find it.

1) is there existing web app to do this?
2) if not, I am on wifi, with apache mod-wsgi python enabled, so I
could use that?

Re: client server console app with cmd library

[Jake b]

Networking can be hard. I'd suggest checking out these libs.

pygame mastermind:
http://www.pygame.org/project-Mastermind+Networking+Lib-859-1773.html
podSixNet : http://mccormick.cx/projects/PodSixNet/
twisted: http://wiki.python.org/moin/Twisted-Examples
lots of references in the  answers to this StackOverflow post:
http://stackoverflow.com/questions/78704/good-python-network-programing-resource

Twisted is the hardest in that list to get into.

Help choosing license for new projects

[Jake b]

I'm starting a new python code project. What license do you suggest? I
am searching, but I'm not finding a simple comparison of licenses. So
I don't know which to use. Maybe MIT or Apache or LGPL or BSD?

Are there certain licenses to avoid using because of interaction
problems between libraries using GPL2 / GPL3 / MIT / LGPL. / BSD with
my own?

I want:
1] Pretty much let anyone use it. Users do not have to include source
code, as long as I get credit. (which I think normallly is a textfile
with project url + name?)

2] (if it matters) I will be using different combinations of pyglet,
pygame, wxPython, etc.

3] I want the option to use my own code in something commercial at a later date.

Does #3 complicate things, or is fine when including author info?

The choices for google code projects are:
  Apache License 2.0
  Eclipse license 1.0
  GPLv2
  GPLv3
  GNU lesser GPL
  MIT license
  Mozilla Public license 1.1
  New BSD License

thanks for advice,
