Stepping through a multithreaded program

[Fernando Rodríguez]

Hi,

I was trying to step through a first attemp of multithreaded script (see
below), with PythonWin, but I'm gettign a very strange error:

---------------------------------------------------------------------------------
import threading

times = 100
delay = 10000

class egoistThread(th reading.Thread) :
def __init__(self, id, times, delay):
threading.Threa d.__init__(self )
self.id = id
self.times = times
self.delay = delay
def run(self):
for i in xrange(self.tim es):
print self.id,
for j in xrange(self.del ay):
pass

egoists = []
for elt in 'abc':
egoists.append( egoistThread(el t, times, delay))

"""
When I reach this point, I get a weird error see below
"""
for ego in egoists:
ego.start()
for ego in egoists:
ego.join()
------------------------------------------------------------------------------

The error is:
Traceback (most recent call last):

Any ideas? O:-)
