How to apply a logical operator to all elements in a python list

Question

I have a list of booleans in python. I want to AND (or OR or NOT) them and get the result. The following code works but is not very pythonic.

def apply_and(alist         


        

Answer 1

As the other answers show, there are multiple ways to accomplish this task. Here's another solution that uses functions from the standard library:

from functools import partial

apply_and = all
apply_or = any
apply_not = partial(map, lambda x: not x)

if __name__ == "__main__":
    ls = [True, True, False, True, False, True]
    print "Original: ", ls
    print "and: ", apply_and(ls)
    print "or: ", apply_or(ls)
    print "not: ", apply_not(ls)
