count python

"""Find all occurrences of element in list"""

# If you simply want find how many times an element appears
# use the built-in function count()
def find_occur(lst, item):
	return lst.count(item)

# Test -----------------------------------------------------------
print(find_occur([None, None, 1, 2, 3, 4, 5], None)) # 2

# If you wanna find where they occur instead
# - This returns the indices where element is found within a list

def find(lst, item):
    return [i for (i, x) in enumerate(lst) if x == item]

# Test Code ------------------------------------------------------
from random import randint, choice

item = choice(lst) # item to find
