Convert the keys of a dictionary to list

Question

I have a dictionary which has usernames and passwords. Now I want to get a list of these usernames. I want to create a list of these usernames from the dictionary. How can I do this?

Answer 1

Unpacking with * works with any object that is iterable and, since dictionaries return their keys when iterated through, you can easily create a list by using it within a list literal.

>>> newdict = {1:0, 2:0, 3:0}
>>> [*newdict]
[1, 2, 3]
