How to Iterate through the Keys of a Dictionary and Lowercase them?

Question

I have this dictionary of lists:

Dict = {'Name':['John','Seth'], 'Gender':['Male','Male'], 'Zip':['68112','22200']}

How to iterate through the keys of this list and make them in lowercase?

The output should be like:

Dict = {'name':['John','Seth'], 'gender':['Male','Male'], 'zip':['68112','22200']}

I have reviewed the solution by Rich Copeland, but It was not evident to me how to apply.

Any idea how to solve this?

I figured out how to fix it! here, use this:

Dict = {'Name':['John','Seth'], 'Gender':['Male','Male'], 'Zip':['68112','22200']}
for key in Dict:
    Dict[key.lower()] = Dict.pop(key)
print(Dict)

if that answer is not enough for you, you should definately review some more beginner tutorials — Joran Beasley, Jun 19 '16 at 20:51
This should do the trick: `{k.lower():Dict[k] for k in Dict.keys()}` — MaxU - stand with Ukraine, Jun 19 '16 at 20:52
I got it now ... I am new to python and not used to dictionary comprehension notation. — MEhsan, Jun 19 '16 at 21:00

this will only work for python 2.7 + (which is probably fine ...) ... and really doesnt add anything that the answer this was closed as duplicate doesnt cover... it should really be a comment instead of an answer – Joran Beasley Jun 19 '16 at 20:56
