Proper way to remove keys in dictionary with None values in Python

Question

What is the proper way to remove keys from a dictionary with value == None in Python?

Answer 1

You can also do this using the del command

   f = {};
   f['win']=None
   f
   => {'win': None}
   del f['win']

Or if you want this in a function format you could do:

def del_none_keys(dict):
    for elem in dict.keys():
        if dict[elem] == None:
           del dict[elem]
