I have created a program in python which is a list of multiple data types and we are trying to sum only int types

a=[4,5,6,False,8,'18']

sum=0
for i in a:
    if isinstance(i,int):
        print("i=",i)
        sum+=i
        print(sum)

But even for False isinstance is showing True. kindly update why

Booleans are a subtype of integer. `True == 1`, `False == 0` – Barmar Jul 31 '21 at 06:22

So how can we leave boolean out and add only ints. Any suggestions @TomRon – user2779311 Jul 31 '21 at 06:30
Change the if condition to - `if isinstance(i, int) and not isinstance(i, bool)` – Tom Ron Jul 31 '21 at 09:22
