Python filter(None) from list example code

Simple example code.

list1 = [10, None, 30, None, None, 60, 70, None]

res = list(filter(None, list1))



Python filter none from list

Remove the None value from a list without removing the 0 value

A list comprehension is likely the cleanest way:

L = [0, 23, 234, 89, None, 0, 35, 9]

res = [x for x in L if x is not None]


There is also a functional programming approach but it is more involved:

from operator import is_not
from functools import partial

L = [0, 23, 234, 89, None, 0, 35, 9]
res = list(filter(partial(is_not, None), L))


Output: [0, 23, 234, 89, 0, 35, 9]
