Is there a function to find the average value of an array of boolean variables in Python3?

Question

Python

Is there a function in python or some library that finds the average value of an array with boolean variables?
Those. Returning True If more than half of the variables in the array are (not) strictly True?
Or

def binmean(data):
    count = 0
    for i in range(len(data)):
        inc(count) if data[i]
    return True if conut >= len(data)/2 else False

The fact is that if it is standard, it will work faster (probably)
(Python loops do not differ in speed)

Answer 1

f = lambda data: data.count(True) >= len(data)/2
