Pls help.help You mean like this?>>> line ='Owner:Bn'>>> line = line.split(":")>>> print line
['Owner', 'Bn']>>> print line[1]BnSo you read the lines from the file till you find "Owner:Bn" and split it at the ':'.

Yes, but maybe it's simpler to use the builtin functions, and slicing:

text = open('the_file').readlines()  <-- now the_file is in text as a string

start = text.find('Owner   :') + 8   <-- start is the index into the text
 where Owner starts + 8 to point
 to the text you want.
end = text.find('\n', start) <-- end is where the newline is, after
 start.
found = text[start:end].strip()  <-- found has the text you want, with
 any spaces stripped off.

I hope it helps.  I didn't test it.

Ooops.  This should be:

text = open('the_file').read()

Maybe someone else will show you the readlines() solution.  I have to
run.

Good luck.

[Tutor] Documentation

[Paul Kraus]

I have been working through a couple of books and learning alot. However I 
can't seem to find any easy way to learn more about different methods and 
commands.

For instance what are all of the methods that can be applied to lists and what 
do they do and how do they work. Or in TKinter what are all the different 
things can I do with a button besides just setting the command and the text 
and such. These are just examples.

I can't find an easy way to do this.

I know there has to be i have tried the pydoc gui but I found nothing when i 
searched list. *shrug*

Thanks for the fast response. This was exactly what I was looking for. One 
last question how would I 'call the method keys'. from the example above.

To be honest ... I don`t know.  I don't use Tkinter myself.  Here's
what I get from the help function:
-
>>> help(Tkinter.Button.keys)
Help on method keys in module Tkinter:

keys(self) unbound Tkinter.Button method
Return a list of all resource names of this widget.
---
So, I would guess that, after creating a button, through something like
aButton = Button(parent, text="Some label", command=some_action)

You could do:
resources = aButton.keys()

There is a free book on using Tkinter to be found at
http://infohost.nmt.edu/tcc/help/lang/python/tkinter.html

Another great resource is to be found on
http://www.pythonware.com/library/index.htm

You will find there a Tkinter reference book on-line (html version) or
a downloadable one (pdf).  Here's what I found by browsing...
===
The following dictionary method also works for widgets:

keys() => list

Return a list of all options that can be set for this widget. The
name option is not included in this list (it cannot be queried or
modified through the dictionary interface anyway, so this doesn't
really matter).
===

You may have to wait until tomorrow to get your answer, when the "real
tutors" are online ;-)

Good luck!

If b is a Tkinter.Button, then it means call b.keys().

eg:

>>> from Tkinter import *
>>> tk = Tk()
>>> b = Button(tk, text='Hello world!')
>>> b.keys()
['activebackground', 'activeforeground', 'anchor', 'background', 'bd',
'bg', 'bitmap', 'borderwidth', 'command', 'compound', 'cursor',
'default', 'disabledforeground', 'fg', 'font', 'foreground', 'height',
'highlightbackground', 'highlightcolor', 'highlightthickness',
'image', 'justify', 'overrelief', 'padx', 'pady', 'relief',
'repeatdelay', 'repeatinterval', 'state', 'takefocus', 'text',
'textvariable', 'underline', 'width', 'wraplength']

So, these are the possible things you can configure with a Tkinter.Button.

Also, the online documentation at python.org is very good.  I
recommend going to http://www.python.org/doc/ and downloading the
current documentation.  You'll get a bunch of HTML files which you can
put somewhere.  Then set up a bookmark for the main index file.  I
have it on my browser's toolbar and I use it all the time :-)

The Library Reference is particularly useful.  For example, if you
want to know about all the methods specific to lists, you can read the
section on mutable sequence types:
http://docs.python.org/lib/typesseq-mutable.html

HTH!

Hi Akanksha,


Have you looked at 'pdb' yet?

http://www.python.org/doc/lib/module-pdb.html

Several of the major Python IDEs also provide some kind of debugging
support; you may want to check them out.  Here's a good link to them:

http://wiki.python.org/moin/IntegratedDevelopmentEnvironments

I've heard interesting things about Komodo and eric3, though I've never
used them personally.


Best of wishes!

[Tutor] installing python on windows and macs

Hi Linda,

But that's somewhat odd, because it should take zero time: Python's
already installed under Mac OS X 10.3.  *grin*

Is this a really big problem for you?  Installation is something that
usually happens just once, so I'm sure the Python developers haven't done
anything particularly focused to make installation on any platform
blazingly fast.  So, frankly, as long as the installation worked out ok, I
wouldn't worry too much about this.


Still if this does matter to you, let's see... can you be more specific
about what version of Mac OS and what installation of Python you've tried?
I made a flippant comment above, but I assume that you mean some other
version of Mac OS (perhaps 9?)  In order to evaluate what's happening, we
need details about your system to advise better.  And since your question
is about speed, knowing what kinds of machines we're comparing against
(CPU, RAM) would also be good, since your computer's raw performance is a
significant factor.

You might also want to talk with the MacPython folks, and you can give
them numbers on how long the installation takes. (How long do you mean by
"long"?  Minutes, hours... days?  *grin*)  The folks on the macpython list
might be able to corroborate that your situation is unusual, or they might
be able to point out something that they know as an outstanding issue.
They have a mailing list here:

http://www.python.org/sigs/pythonmac-sig/

Good luck to you.
