* means "matches remaining positional arguments (in a tuple) =0D
** means "matches remaining keywords arguments (in a dictionary) =0D
=0D
if define function: =0D
def foo(*bar, **kwargs): =0D
print "positional arguments:" =0D
for arg in bar: =0D
print arg =0D
print "keyword arguments (kwargs):" =0D
for kwarg in kwargs.keys(): =0D
print kwarg + ":" + kwargs[kwarg] =0D
=0D
then you can call it by foo('spam','eggs','toast',kwarg1=3D'scam',kwarg2=3D=
'slam=0D
). You will get result: =0D
positional arguments: =0D
spam =0D
eggs =0D
toast =0D
keyword arguments (kwargs): =0D
kwarg2:slam =0D
kwarg1:scam =0D
=0D
-mico- =0D
