Re: Newbie question - clearing screen @ interactive prompt

Well, you can run any system command from within Python as well: import os os.system('clear') But I'm not sure this will help in this case. Are you trying to program a console app in Python? If so, you may want to look into curses module or other console lib that has Python bindings (like newt)

I'm trying to get the results of binascii.crc32 to match the results of another utility that produces 32 bit unsigned CRCs. binascii.crc32 returns results in the range of -2**31-1 and 2**21-1. Has anyone ever worked out any "bit twiddling" code to get a proper unsigned 32 bit result from binascii.

Python iterates over "things" (objects), of which integer numbers are just one possible choice. The range built-in command produces ranges of integers which are useful for tasks such as this. lim = 3 for i in range( 1, lim+1 ): for j in range( i+1, lim+2): for k in range( j+1, lim+

Proposal: Inline Import

Here's a heretical idea. I'd like a way to import modules at the point where I need the functionality, rather than remember to import ahead of time. This might eliminate a step in my coding process. Currently, my process is I change code and later scan my changes to make matching changes to t

Thoughts on object representation in a dictionary

Say I have classes which represent parts of a car such as Engine, Body, etc. Now I want to represent a Car in a nested dictionary like... {string_id:{engine_id:engine_object, body_id:body_object}}ok? Well the other thing is that I am allowed to store strings in this dictionary...so I can't j

Re: Moving a package in cygwin

Ok, thanks. I actually hadn't considered the build system, figuring that function names, etc., would somehow magically be "exported" to anyone wanting to use the .pyd library. Michael -- http://mail.python.org/mailman/listinfo/python-list

PHP = Perl Improved

recently i got a project that involves the use of php. In 2 days, i read almost the entirety of the php doc. Finding it a breeze because it is roughly based on Perl, of which i have mastery. i felt a sensation of neatness, as if php = Perl Improved, for a dedicated job of server-side scripting. Ev
