Question

I am scratching my head on what is going in the following code.

class foo(object):
    def __init__(self,*args):
        print type(args)
        print args

j_dict = {'rmaNumber':1111, 'caseNo':2222} 
print type(j_dict)
p = foo(j_dict)

it yields :

<type 'dict'>
<type 'tuple'>
({'rmaNumber': 1111, 'caseNo': 2222},)

It seems to me that this code converts a dict to a tuple!! Can anyone explain this

Answer 1

Actually it’s because args is a tuple to hold a variable length argument list. args[0] is still your dict – no conversion has taken place.

See this tutorial for further information about args and kwargs (the keyword version of args).
