Untest no-brainer with "eval", there might be better solutions:
>>> import random
>>> for d in dir(random):
... print eval('random.%s.__doc__' % d)

[Tutor] Eclipse and Member Function Availability
I am building a class and using a "main.py" script as the "driver" for testing. Where I am having problems is that the class is defined in another file ( say the class is "MyClass" and the file is "MyClass.py" that I am importing as a module. The problem itself ( not a major one ), is that when using autocomplete feature within Eclipse, where you type in the name of the module or a class and it lists the functions/variables that are available in a popup menu, it only shows the modules methods and variables. Hopefully this example will make things clear: -- import MyClass def main(): myObject = MyClass.MyClass """ Here I type in the name of the class, expecting a list of the classes member functions/etc to popup """ myObject. """<--- here I see a list of functions available to the module, not the class """ main() - Now, if I take all of the classes methods out of the class and make them global within the module file, then I can see all of them using the autocomplete function, however, doesn't this defeat the purpose of OO? Should I use a module instead of a class, and pretend the module is a class? This would make the autocomplete available but make it more difficult to migrate the code from Python to say, Java or C++. Any advice is welcome. Thank You, John A. Gooch Systems Administrator IT - Tools EchoStar Satellite L.L.C. 9601 S.

[Tutor] Formatted writing to a file
I am trying to write to a file multiple times before close. Using the following sequence:
outfile = open(data_file, 'w' )
x=5
while x > 0
x = x - 1
datax is read from a file.
outfile.write('%25s' %datax + "|\n")
This loop will write 5 lines at column position 25. I later come back to the same code and want to write 5 more lines at column 50.
My questions are:
1. how can I format outfile so i can write multiple lines and then apend multiple lines later before closing the file?
2. how can I make data formatting string '%25s' intiger (in this case 25) a variable?
Thanks in advance.

I asked for help on my problem but unfortunately now help
yet. I am trying to put up instructions for a board game and then have the
person read and then proceed onto the game. The following is what I have that
displays the instructions just fine but will not let the game proceed on to the
board and the game.:
The instruction section works fine and the game part works
fine but not together. I guess I need the widget to have a button that allows
the reader to proceed.

I have the need to run periodic searches on the US Patent and Trademark Office website, www.uspto.gov. Before I reinvent the wheel, I thought I'd check to see if anyone knew of such a beast.

Then I want to be able to parse out the patent metadata, e.g. inventor names, dates filed and issued, etc. Has this already been done?

[Tutor] Help: wget-- how does it work?
One of my favourite unix applications is wget. Thinking how easy (and fun) it might be to implement with pythons excellent librairies has led me to a few questions. First, I found the progress bar class from aspn http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/168639 This could be used to simulate wgets progress bar. What I'm trying to figure out now is how one would stat a file as it was being downloaded so that I can feed information to the progress bar, and what the most optimal way to do this is? I realize you could request the filesize if it was on an ftp server, and then use 'os' to check the filesize. But how would you do this with regular http? Are there any tricks the experts have? How does wget do it? -thanks ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

You can get the content-length header from the object returned from
urllib2.urlopen():
>>> import urllib2
>>> f=urllib2.urlopen('http://www.google.com')
>>> f
>
>>> f.info()
>>> i=f.info()
>>> i.getheader('content-length')
'1983'
Now you can read the data in chunks (using f.read(n)) and update your status
bar as you go.
