dict.fromkeys all point to same list

Question

This was causing me a bit of grief...

I created a dictionary from a list

l = [\'a\',\'b\',\'c\']
d = dict.fromkeys(l, [0,0]) # initializing dictionar         


        

Answer 1

You could use a dict comprehension:

>>> keys = ['a','b','c']
>>> value = [0, 0]
>>> {key: list(value) for key in keys}
    {'a': [0, 0], 'b': [0, 0], 'c': [0, 0]}
