How to remove all 0 from a dictionary in python? [closed]

Question

Lets say I have a dictionary like this:

{'1': 2, '0': 0, '3': 4, '2': 4, '5': 1, '4': 1, '7': 0, '6': 0, '9': 0, '8': 0}

I want to remove all items with a value of zero

So that it comes out like this

{'1': 2, '3': 4, '2': 4, '5': 1, '4': 1}

Answer 1

Use a dict-comprehension:

In [94]: dic={'1': 2, '0': 0, '3': 4, '2': 4, '5': 1, '4': 1, '7': 0, '6': 0, '9': 0, '8': 0}

In [95]: {x:y for x,y in dic.items() if y!=0}
Out[95]: {'1': 2, '2': 4, '3': 4, '4': 1, '5': 1}

Answer 2

Use a dictionary comprehension:

{k: v for k, v in d.items() if v}
