[Python] How to create a dictionary from a list of keys, but set all values to 0?

I've found elegant solutions to create dictionaries from two lists:

keys = [a, b, c]
values = [1, 2, 3]
list_dict = {k:v for k,v in zip(keys, values)}

But it should be possible with syntax something simple like:

dict_totals = {k:v for k,v in zip(keys,range(0,3))}


I'm hoping for output that looks like {a:0, b:0, c:0}. Am I missing something obvious?
