Re: [Tutor] Tutor Digest, Vol 106, Issue 31

Hi Python tutor
I have a question I believe I have posted before: when you have filled the page 
with text (commands,list etc) how do you clear the page to allow a clean page 
to continue on writing script?
Thanks appreciate your help.

Subject: [Tutor] Using json to filter out results from a dictionary
Message-ID:

Content-Type: text/plain; charset="iso-8859-1"

Hello,

I've just started programming in python and haven't had much experience with 
json. I've written this simple script that makes a request to the Bitly API, 
specifically the 
/v3/realtime/bursting_phrasesendpoint,
and prints the response into terminal. What I want to do is take the response 
and filter out a portion of it so I only see the data I find important. So far 
I've used json to load the results into a dictionary, however I'm stuck in 
terms of how you loop through the dictionary and only print out certain keys 
while dumping the rest.

To illustrate, this is the script:

import urllib2


CLIENT_ID = "0367d81a428968a57704a295a4378521af81c91b"

CLIENT_SECRET = "404862446e88f391e8c411ca1ee912506d64fffd"

ACCESS_TOKEN = "53a01f38b09c0463cb9e2b35b151beb127843bf3"

BITLY_ENDPOINT = "
https://api-ssl.bitly.com/v3/realtime/bursting_phrases?access_token=
"+ACCESS_TOKEN


def getServiceResponse():

url = BITLY_ENDPOINT

request = urllib2.Request(url)

response = urllib2.urlopen(request)

d = json.loads(response.read())



getServiceResponse()


In terminal I run this command: python /file/location/file.py | tr "," "\n"
which returns a long list of results like this:


"data": {"selectivity": 3.0

"phrase": "justin bieber"

  "mean": 0.089997}

  {"std": 0.046334721206249076

  "ghashes": [

 {"visitors": 440

 "ghash": "QXfZfQ"}

 {"visitors": 215

 "ghash": "W9sHrc"}

 {"visitors": 92

 "ghash": "XY9PPX"}]

  "N": 203183.0

  "rate": 0.53003

"urls": [

 {"visitors": 440

 "aggregate_url": "http://bit.ly/QXfZfQ"}

 {"visitors": 215

 "aggregate_url": "http://bit.ly/W9sHrc"}

 {"visitors": 92

 "aggregate_url": "http://bit.ly/XY9PPX"}]


How do I use json to filter out the "ghashes" from what is printed into 
terminal so that the results look like this instead?:

"data": {"selectivity": 3.0

"phrase": "justin bieber"

  "mean": 0.089997}

  {"std": 0.046334721206249076

  "N": 203183.0

  "rate": 0.53003

 "urls": [

  {"visitors": 440

 "aggregate_url": "http://bit.ly/QXfZfQ"}

  {"visitors": 215

  "aggregate_url": "http://bit.ly/W9sHrc"}

  {"visitors": 92

 "aggregate_url": "http://bit.ly/XY9PPX"}]


Any help would greatly be appreciated, thank you!

This is not really a JSON problem. JSON just handles converting data in a dict 
to a string and back. As you say:

> print out certain keys while dumping the rest.

That part is simple:

for key, item in mydict.items():
 if key != "rubbish":
 print key, item
 # In python 3, use "print(key, item)" instead


Another way:

if "rubbish" in mydict:
 del mydict
print mydict
# In python 3, use "print(mydict)" instead

Re: [Tutor] Tutor Digest, Vol 106, Issue 31

If you reply to the digest email you should to do two things:
1) Change the subject line to match the email you are replying to (or
in this case choose a new subject).
2) Delete any part of the message that you are not responding to (in
this case all of it).

In fact why are you replying to the digest email when you are not
replying to any of the messages in it? If you want to send an email to
the tutor list you can just do "new mail" or equivalent in your mail
client and then type "tutor@python.org". In my mail client I only have
to "t" and "u" for "tutor" and then the software will auto-complete
the remainder of the address.
Replying to the digest instead seems pretty lazy to me.

What page are you talking about? Where are your commands being typed?
Are using a terminal or IDLE, or something else?

Perhaps you could try typing the command "clear".

Mike,

Please start a new thread for a new question rather than replying to the
digest as you have done. This avoids a tonne of text irrelevant to your
question (which I have removed) and affords you the easy to avail yourself
of oportunity to give your inquiry a meaningful subject line.

What do you mean by 'page'? What software are you working with? What OS?
You've not given enough information.

If you are thinking of an interactive prompt (though you don't seem to be)
you can clear it with

print "\n" * 80 # or some appropriate value

If that doesn't help, please ask again with enough information about your
context to allow those willing to help you to do so.

Best,

Brian vdB

Further to previous comments, It is also preferred to send emails to
this list in plain text rather than html. This is because it protects
the formatting of Python code and works better with all possible
mail-clients/news-readers/archives etc.

It's still not clear what you are referring to. What piece of software
is responsible for the "page" you are referring to? The Python
interpreter itself does not have a "page".

If you run Python in a terminal, then the terminal shows a page of
commands and output. If you run Python commands in IDLE then you will
be typing your commands and viewing their output in the IDLE page. If
you edit a .py file then your editor will show you a page (although
the file itself is not really divided into pages).

Can you please clarify very specifically what this "page" is and/or
what you are doing that leads to the page being there?

I'm assuming you're using the interpreter in IDLE?

Try 'Control + L', if memory serves.

Are you talking about the DOS box (CMD window, terminal, or any other
alias)?  If so, it could be any size, from a few lines up to maybe 50
(or more, depends on the screen resolution of your particular tube). 
And what do you mean by full?   When your program is generating output
with print statements, once it reaches the bottom of the DOS box, it'll
scroll.  Python has no control over that.

If your version of CMD supports ANSI sequences, you could print ESC 2 J
from your program when you want the screen cleared.  But easier is just
to print a boatload of newlines, and figure that'll scroll the old stuff
off.

[Tutor] Which version of activetcl to use for Mac OS X 10.7?

[Yi Molina]

Hi, all. I am new to python and just installed Python 2.7.3 on my Mac OS X 
10.7.5 from python.org. I read that I am supposed to use  ActiveTcl 8.5.11.1. 
So I clicked on the link on but found only 
ActiveTcl8.5.11.1.295590-macosx10.5-i386-x86_64-threaded.dmg, Which is for MAC 
OS X 10.5. I could not 
find anything for OS X 10.7, so I installed it.  I tried a few simple programs 
in IDLE and they work fine. But I'd like to confirm if this is the right 
activetcl version to use?

Thanks!

[Tutor] Learning Python through automating web application testing.

[marcusw4...@hotmail.co.uk]

Hello all,

I'm new to posting on mailing lists so hopefully I've picked the correct
one for my question(s).

A little about my programming experience first.

I work as a 'black box' software tester on a website/application so am
familiar with the IT development process but when it comes to
programming I'm very much a keenly interested newbie. To give you some idea
of my current ability it would be (with a bit of revision) around chapter 8
of Wesley Chun's "Core Python programming".

I do not in any way mean this as a criticism of "Core Python" but to learn,
what I really need is a project. Although "Core Python" rigorously tackles
it's subject; I've found I need a more tangible reason than "It would be
great if I could program" to stay focused on working my way through the
book. It took more than one attempt to get to chapter 8 and as I was
stubbornly refusing to ask for help (madness I know) it became quite
disheartening when I found some questions tough going. It will be an
invaluable point of reference in the future, it's simply I don't currently
need to understand it's subject with the depth it offers.  All I need at
the moment is "enough to get started" which by my rough calculation is
around 4.35% (not including appendices) of what "Core Python" has to offer!

So what I need is a small(ish) project that introduces thoroughly a useful
part of the Python language while teaching me how to program.  But for what
will sound like a silly reason I've always managed to avoid undertaking
this task. Basically a fear of failure has stopped me from starting. I mean
I've always talked a good game but what if I'm not sharp enough to learn to
competently program?  Not attempting is better than failing surely?

Because of this fear I've never admitted I've got a ready made project just
waiting for me to tackle...

Until now!

I would like to learn to automate the testing of a http(s) web
site/applications but feel slightly overwhelmed by this task so would like
to ask for some initial guidance.

These are some of questions that I have.

How do I go about this?

Where do I start?

There's just so much out there to help with learning Python I'm
experiencing information overload!

How do I stop myself from trying to run before I can walk?

In a perfect world a step by step guide, in automating web tests, using
Python is what I'm after but failing that(!) which sites/forums/mailing
lists are of particular interest to someone who would like to learn Python
programming initially through automating web tests?  (By web tests, to
begin with, I mean automated regression testing of a site by multiple users)

At work we use Selenium and Java so I'm aware that Selenium comes with a
Python driver.  Would that be a good place to start?

Apologies if I'm not supposed to ask more than one question per mail but
these are all closely related and could be thought of as "newbie struggling
to see the wood/forest for the trees!"

Many thanks for your help

Regards
Marcus

Like others I don't really understand what you mean by a page.
But in general you don't need to do that. If you are using the Python prompt
>>>

You just keep adding stuff and it will scroll up.
If you just want some clear space hit return a few times.
Or as already suggested:

print '\n' * 50   # prints 50 newlines...

But it all depends on what tool you are using to enter your Python
code. You may have something odd that has a fixed screen but if so
I've never come across it!

main calls showMenu which calls showMenu which calls showMenu etc

You need to break the cycle of showMenu calls. Thats usually done by 
inserting some kind of check before the call to showMenu inside showMenu 
 so that you only call it when needed.


However I suspect what you really need here is to use a loop instead of 
having showMenu calling itself.


choice = None
while not choice # or some other test condition here
   choice = showMenu()

You need to define path_1pt1 *before* simpstart.  Also, about not “free source”:
(a) did you mean: open source?
(b) why did you publish it here?

I usually recommend installing from a package management system and 
not manually installing. You can use MacPorts or Homebrew for OS X 
and they will take care of selecting an appropriate Tcl version.

This (MacPorts) may require you to install some developer tools 
like XCode but the process is *very* simple. I am personally unfamiliar
with Homebrew so I am not sure of their requirements.

Why bother attaching the file and not just include the relevant
text in the email (summarizing as you can)? Many people are reluctant
to open an attachment and I can see nothing in the attachment other 
than text. Also, you would be better served by posting in plain text 
(not "rich" mode or HTML) as HTML emails can mangle code causing it to 
be unreadable.

As for your assignment, what is giving you trouble? To me this is clear 
and well documented. I wish my professors in college (or school) had
given me such complete assignments! Do you have code that is giving you 
a problem? If not, why do you not have an attempt? How can we help you 
otherwise?

Hi Tutor,
I'm getting this error

Traceback (most recent call last): File "C:\Users\Jack\Desktop\python\g.py",
line 45, in  path_1pt1()
NameError: name 'path_1pt1' is not defined



Names need to be defined before they are used. Code needs to be indented to
be inside a function, if it is not indented then it is considered to be part
of the "top level" code that runs immediately.

So you begin a new function, simpstart:



def simpstart():
   global ammo
   global health
   global tech_parts
   global radio_parts


By the way, you can consolidate those four lines to one:

global ammo, health, tech_parts, radio_parts


But here you lose the indentation, so Python considers the following to
be "top level" code and executes it immediately:


print "You awake in a haze. A crate,a door and a radio."
g1 = raw_input("Which do you choose  ")


Questions in English should end with a question mark, or people will
consider you ignorant and illiterate. Unless you are a famous poet
or artist, in which case they will fawn over how transgressive you are.



if g1 == "CRATE" or g1 == "Crate" or g1 == "crate":


What if they type "cRAtE" or "crATE"?

Much simpler to do this:

if g1.lower() == "create":

By the way, you will find programming much, much simpler if you always
use meaningful variable names. "g1"? What does that mean? A better name
would be something like "user_response", or even just "response".

So, skipping ahead, we come to this bit:


elif g2 == "NORTH" or g2 == "North" or g2 == "north":
 path_1pt1()


Again, this is better written as "if g2.lower() == 'north':".

At this point, Python then tries to call the path_1pt function, but it
hasn't been defined yet. So it gives you a NameError.

How do you fix this? Simple: this entire block of code needs to be
indented level with the global declarations at the start of simstart.

(Fixing this error may very well reveal further errors. Good luck!)

Another comment:



#A Towel Production
# APOC
#---
global ammo1
global ammo2
global ammo3
global health
global tech_parts
global exp
global radio_parts


These seven global lines don't do anything. They are literally pointless. One
of the mysteries to me is why Python allows global declarations outside of
functions, but these lines literally do nothing at all except fool the reader
(you!) into thinking that they do something. Get rid of them.



ammo1=10
ammo2=0
ammo3=0


I note that you have three variables, "ammo1" through "ammo3", but in the
simpstart function, you declare a global "ammo".

Re: [Tutor] Clearing Python text

[Mike G]

I use Windows XP, Python 2.7, Notepad++ as my editor, and generally
run my .py files from cmd, this is how I toggle between running my .py
file after an edit (and save) and subsequently clearing the screen -
it's pretty easy.

I "arrow-up/arrow-down" on the keyboard to reprint (type) the latest
command in cmd, this toggles between running my .py file...
runs my file ... C:\Python27\MyScripts>python helloworld.py

and to clear whatever printed to the screen...
clears the screen ... C:\Python27\MyScripts>cls

Once you've typed both at the prompt just arrow up or down, then hit
enter - file run or screen cleared, as well saves time retyping.

Sorry if I missed it but this works for me because I too prefer to
print to a cleared screen, don't know why, just do.

Mike :)

guys i think ive got it. The & in that comprehension was really
confusing me, but i found out it means intersection, so i took the
sets manually and saw the results i got using intersection and it
became more clear from there. A Big Thanks if you took the time to
help solve my issues.
