With Python, the filter function can check for any None value in the list and remove them and form a filtered list without the None values.
Python filter(None) from list example code
Simple example code.
list1 = [10, None, 30, None, None, 60, 70, None]
res = list(filter(None, list1))
print(res)Output:
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]
print(res)
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))
print(res)
Output: [0, 23, 234, 89, 0, 35, 9]
