It's probably worth pointing out that these two functions are not entirely equivalent:
def t1():
if condition:
return True
return False
def t2(): return condition
...
>>> if t1(100) == True: print '100 is True' ... 100 is True
>>> if t2(100) == True: print '100 is True' ... (nothing prints)
If you really need this property, you may use type-conversion with bool:
>>> t2(100) 100 >>> bool(t2(100)) True >>>
So in this case
def t3(a):
return bool(a)should work correctly

Remark for Brian: Please note, that Kent wrote about a feature specific to Python, whereas the main part of this thread contains considerations concerning boolean expressions in general. _______________________________________________ Tutor maillist - [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/tutor
