[Tutor] Trouble with sys.path.append

[aug dawg]

Hey all,

Earlier today, I tried to add a folder to my PYTHONPATH. When I tried
sys.path.app('location/of/folder'), the command successfully executed it,
but then when I did sys.path to check to see if it was now in my PYTHONPATH,
it was not there. Does anyone know what might be causing this?

Thanks!

Yes except that its not urandomthat is printing those values.
urandom returns a string of bytes.
Its the Python interpreter calling the repr() function on
those bytes that is deciding to print either hex or character.
Try this:


'\x6c\xbb\xae\xb7\x0f\x74'

'l\xbb\xae\xb7\x0ft'

print '\x6c\xbb\xae\xb7\x0f\x74'

In the first case its the repr() of the string that gets
printed in the second its the str(). Its the conversion
function that determines what gets printed not urandom()

How were we supposed to know that all the hexes have 2 digits? How 
did you?


Simple arithmetic...
Its the hex representation of a byte. A byte is 8 bits long.
A hex digit represents 4 bits (-) so you need 2 hex digits to
represent 8 bits or one byte.

Yes thats a good point. Most books (including mine) focus on how to
write code. Very few tell you how to distrubute it! And that's not 
just

in Python, most programming books are the same.

Interesting.

os.urandom() doesn't *print* anything. It RETURNS a byte string. What 
you do with it is your business.

In your case, you fail to save the return result in a variable, or put 
it in a list, or do anything else with it, so the interactive 
interpreter prints it. All that the interpreter sees is bytes. They 
could have come from a hard-coded literal:

>>> 'l\xbb\xae\xb7\x0ft'
'l\xbb\xae\xb7\x0ft'

or a list:

>>> L = ['l\xbb\xae\xb7\x0ft', None, None]
>>> L[0]
'l\xbb\xae\xb7\x0ft'

or some function call:

>>> (lambda c: c + '\xbb'[:] + '\xae\xb7' + 1*'\x0ft')('l')
'l\xbb\xae\xb7\x0ft'


(The above examples are from Python 2.5 rather than 3.1, where byte 
strings aren't flagged with a leading b.)

Because that's what they do. Numbers between 0 and 255 inclusive can be 
written in two hex digits 00..FF, just like numbers between 0 and 99 
inclusive can be written in two decimal digits.

Modifying sys.path doesn't update PYTHONPATH. If you modify sys.path, 
the changes disappear when you exit and re-enter and the unmodified 
PYTHONPATH is read.

Appending to sys.path will only change the module search directory for the
current *python* session. 

If you want to add a directory to the current *terminal* session, then export
PYTHONPATH environment variable into your shell.

If you want to *permanently* add a directory to the module search directory, add
a .pth file to a directory that is already inside a search path (typically in
/site-packages). Alternatively, modify the site.py file. See
here for details: http://docs.python.org/install/#inst-search-path

[Tutor] Reading every 5th line

[nitin chandra]

Hello Everyone,

I am to make a small programme for a friend of mine
where i am to start reading from 14th (string) from a file and then
read every 5th row.

ie.

in 1st read it reads the 14 row in a File, write to an OUTPUT-1 file
Next reads 19th row, write to the OUTPUT-1 file
then 24th row,... so on.

and the second loop does is

reads the 15th line as the first line from same input file and write
to OUTPUT-2 file
next reads 20th line / row, write to the OUTPUT-2 file


I have tried various ways but some how i am ONLY able to do i simple
read from one file and write to another.

There are 3024 rows / lines PER file and there are 24 such file I need
to run the programme on.

I really need this on an urgent basis. can some one please help me in this.

Thanks in Advance

Try using "range(start, end, step)".

If this is for a class exercise, it would be unfair to say more. If it's not

This may help you get started.

FileNames = ["FileName01", "FileName02", ..., "FileName24"]
for File in FileNames:
   List = open(File, 'r').readlines()
   for Start in [[14, "%s-1" % File], [15,"%s-2" % File]]:
   OutList = []
   for Line in range(Start[0]-1, 3024, 5):
   OutList.append(List[Line])

There are many variations, here's one:

Write a loop that executes 14 times. Inside that loop, read one line 
from the input file, and write it to the output file.

Now write a second loop that executes forever. (Don't worry, you'll 
break out of the loop at some point.) Inside the loop, read one line 
from the input file, and write it to the output file. Then read four 
more lines, and throw them away. If you read a line, and it's empty, 
then you've reached End Of File (EOF) and you can break out of the 
loop.

[Tutor] Questions regarding strings

[Daniel]

Hello everyone! I would like to ask you two questions regarding strings
which I do not know. Excuse me in advance if the questions may seem a bit
dumb. I'm a beginner. So let's get back to the point, this is my string:

msg= 'Hello world'
If I do, msg[:3] I get the following output, 'Hel'
If I do, msg[6:] I get the following output, 'World'
Ok, so I understand why this is happening. What I do not understand is why I
get the following output in this cases.


1) msg[:-1] which has the output 'Hello Worl'
2) msg[0:6:2]  'Hlo'
3) msg[::-1] 'dlroW olleH'

Can someone please explain this to me? Thank you so much and I wish everyone
a great day!

negative indexes start from the end of the string. So msg[-1] == 'd',
and the slice there means "start at the first character, and go up to
the last.

> 2) msg[0:6:2]  'Hlo'

This means start at the first, up to the sixth, making steps of 2.
Steps of two means every other letter is skipped, of course.

> 3) msg[::-1] 'dlroW olleH'

This slice catches the whole string, but makes steps of -1, which
essentially means you'll go through the strings backwards.

Yes, I want to endorse that!

Distributing your software is IMHO a worthy subject for any Python website or 
book. Especially because there is this idea, that all important components for 
software development are included in Python.

With Distutils, EasyInstall (*.egg), and Python Package Index there really 
exist an integrated build system with installer, a package manager, and a 
networked software repository. 

Additionally with Virtualenv or Buildout one can build encapsulated 
environments for testing or deployment, without fear for conflicting library 
versions.

Someone however needs to find out how these components fit together, and then 
write a nice introduction on the subject.

Write a function that takes a pair of filenames and the starting line # 
to begin reading.  Then call it in a loop from 14 through 19.  And call 
that loop for each input file.


The loop inside the function body could be as simple as (untested):

   for line in itertools.islice(infile, startnum, 10**6, 5):
 outfile.write(line)

You cannot use the same python source on 2.5 as you do in 3.1, 
regardless of OS platform.  For just about any non-trivial program, the 
differences will get you compile errors on one or the other.


If you're targeting 2.5 on the remote machine, you'd better be 
developing/testing with 2.5 on your own.  You still might have OS 
differences, but they're more likely to be manageable.


For an example of a gross difference, look at print.

In 2.5, print is a statement, and takes particular syntax following the 
word print.


In 3.x, print() is a function, and must have a standard argument list.  
This means that some options that you might have used in 2.5 will just 
be syntax errors.  And conversely, it means the print function may be 
called inside an expression, which would be totally illegal on 2.5.  It 
is possible to build a string ahead of time, and enclose a single string 
in parentheses (effectively ignored on 2.5), and get something that 
works on both platforms.


Alternatively, there's the 2to3 converter, but that's a nuisance at 
best.  Useful for one-time conversion, and for those situations that 
absolutely must run on both platforms, but otherwise a pain to keep both 
versions of the source up to date.  And you'd still have to test with 
2.5 before deploying to an unsuspecting user.

To add a small comment to what Dave's already said, please refer to the 
official documentation here:

http://docs.python.org/release/3.0.1/whatsnew/3.0.html

The net result for you is, I think, that you should be using Python 2.x 
on your Windows XP box, and not Python 3.x.


Regards,

Walter

[Tutor] Need a mentor

[Ranjith Kumar]

Hi all,
I`m doing a python based project, I need a mentor who can guide me and
help me to complete the project. the idea is fully based upon application
programming. What I want is just suggest me how to implement so that I write
the code and send it back to you. And there you can check the codes and find
the better solution or giving me some other ideas so that we can optimize
the code and bring a better solution. I`m glad to work on python if anyone
interested in this please kindly let me know it. Awaiting for your reply.

Cheers

But
>>> os.urandom(6)
b'\x13\xf1\x138a\xcc'

In my Active Python 3.1 docs, Language Ref 2.4.1. String and Bytes
literals, I have

The same as what you quoted, plus a couple of footnotes:
\xhh Character with hex value hh (2,3)

That footnote 2, "Unlike in Standard C, at most two hex digits are
accepted.", seems necessary; otherwise that \x138a could be seen by my
former, byte-ignorant self as a \x, and puzzled about why I got
only 4 bytes, not 6.  :)

But I never would have thought to have looked in the docs where you did.

The latest of these I have received is dated June 22. Summer vacation?
Or discontinued?

A Gmane search shows that there are frequent gaps.

Re: [Tutor] Reading every 5th line

[nitin chandra]

Hello Dave,

Thank you very much. This solution worked out very well.

And I liked your style of coding  ' In less DO more '.

Thank You once again.

Nitin

PS :- I tried to use a file pointer with raw_input, but that did not work.

[Tutor] Fwd: Need mentor

[Ranjith Kumar]

Hi all,

I have described the theme of my project here,
When the script is runned a configuring window has to be displayed where
the user has to configure for there desired Web Browser, Audio Player, Video
Player, Text Editor (Each Specified in separate SS Tab). Here the script
should retrieve all installed Web Browser, Audio Player, Video Player and
Text Editor and categorized and displayed in their corresponding tab`s. Here
the user has to choose and set their preferred Web Browser, Video Player,
Audio Player, Text Editor and update the configure file.

note 1: configuring window should run automatically only first if the user
wants to reconfigure the file again they should run configuring module
alone
note 2: This script is to start it on every login and stay running on
background until i shut download the machine.

For an example, this is complete real time behavior of the script.
Let us consider I`m the user I downloaded the script and runned it, It
should check for a configuring file if there is no configure file is created
means it should automatically create a new configure file and displays a
configuring window in that window I will be offered by whatever the web
browsers, audio player, video player, text editor installed on my machine
will has to be shown to me in their corresponding tab`s I have to set my
desired web browser if I choose chrome has my prefered web browser and
whenever I press the key "w" on desktop screen the chrome browser should be
opened, I have to set my desired Audio player if I choose exaile has
my preferred audio player and whenever I press the key "a" on desktop screen
the Exaile audio player should be opened,I have to set my desired video
player if I choose vlc has my prefered video player and whenever I press the
key "v" on desktop screen the vlc player should be opened, I have to set my
desired text editor if I choose gedit has my prefered text editor and
whenever I press the key "t" on desktop screen the Gedit text editor should
be opened, this just like creating hotkeys and all these configured details
should be updated when I click on apply and exits the configuring windows
and runs the script at the desktop background while i`m in desktop when i
just hit "w" chrome browser should opened

Are you offering to pay for professional help for a commercial project, 
looking for volunteers to work on an open-source project with you, or 
just looking for a kind and generous soul who is happy to donate many, 
many hours of work teaching you application development in Python?
