I thought __init__ was required to be called explicitly only when you were
doing inheritance and wanted to pass separate value

Hi,
I have, for very long, been trying to find a consistent solution (which
could work across major python platforms - Linux, Windows, Mac OS X)
for the following problem.
I have a function which downloads files from the web. I've made the
function threaded. I'm trying to implement a progress bar
e a couple of seconds for the zip to
complete. During those couple of seconds, if another thread's file (a
couple kb) gets downloaded/copied, will it wait for the lock to be
released or will it create another lock ?
Thanks,
Ritesh
Dennis Lee Bieber wrote:

pping even if that's not true.
My question is, in a code example like this which is threaded, does the locking
mechanism work correctly ?
Or are two different locks being acquired ?

I believe my change has to go into the progress bar class to make it thread

Making the instance "log" global makes it accessible to all the

Hi,
I have a funtion named unzipper() which does the work of unzipping the
files.
Is there a way I can identify what is the type of the file which'll be
passed to unzipper().
If yes, I'll be able to make out if it's a zip file or a tar or a bz2
file.
