#43342 — Can I iterate over a dictionary outside a function ?

[Multipart message — attachments visible in raw view] — view raw

I have a prog in which a functions returns a dict but when I try to iterate
over the dict using iterkeys, It shows an error. I think its because only
address of the dictionary is returned so cannot be iterated upon.

Please suggest some way by which it can be made possible to iterate over
the dictionary using  iterkeys outside the function ?

1) Show us your code in form of a minimal "working" example, "working"
means that it should show us what you expect it to do but at the same
time shows the behaviour you complain about.

2) Show us your actual error message!

Python does not use addresses, it uses references. And as long as you
have a valid reference to a dict assigned to some name in some namespace
you should be able to iterate over its keys using some_dict.iterkeys().
