Is there a way I can initialize dictionary values to 0 in python taking keys from a list?

Question

I have a list to be used as keys for the dictionary and every value corresponding to the keys is to be initialized to 0.

Specifically for your case `dict.fromkeys([1, 2, 3], 0)` would result in `{1: 0, 2: 0, 3: 0}` — Patrick Haugh, Sep 19 '18 at 17:03

You can do with dict.fromkeys

In [34]: dict.fromkeys(range(5),0)
Out[34]: {0: 0, 1: 0, 2: 0, 3: 0, 4: 0}
In [35]: dict.fromkeys(['a','b','c'],0)
Out[35]: {'a': 0, 'b': 0, 'c': 0}

This helps. However what about a list of words as keys? – kramer Sep 19 '18 at 17:16
@NaveedUnjum It will work for the list of words too. Basically it will work for all kind of iterator. – Rahul K P Sep 19 '18 at 17:18
