HELP - Calculating the complexity of my algorithm.

I didn't test it but I think your code can be simplified to something like this

def Comptage(L) :
    zeros = 0
    ones = 0

    for x in L:
        for digit in str(x):
            if digit == 0:
                zeros += 1
            elif digit == 1:
                ones += 1       

    return [zeros, ones]
