Why is my count variable not calculating correct number of True values from the list?-CodePudding

I have a list values_count which contains boolean values True and False. I am trying to calculate number of True values present in the list. For example , for the list ltr=[False,True,True,True] I expect my answer to be 3 but my answer comes 0, the initial value of the count variable that I have declared. Below is my code.

    class Solution(object):

    def count_true(self, values_count=[]):

        am = 0
        for i in values_count:
            if values_count[i] == True:
                am   1
                return am
            else:
                pass


if __name__ == '__main__':
    p = Solution()
    ltr = [False, True, True, True]
    print(p.count_true(ltr))

CodePudding user response：

why not just

ltr = [False, True, True, True]
ltr.count(True)

CodePudding user response：

Actually, am 1 should be am = 1 and return am should be at the last line.

However, you can use my code below:

def count_true(self, values_count=[]):
    count = 0
    for value in values_count:
        if value:
            count  = 1
    return count

Output:

> 3
