String length without len function

Question

Can anyone tell me how can I get the length of a string without using the len() function or any string methods. Please anyone tell me as I\'m tapping my head ma

Answer 1

Here's a way to do it by counting the number of occurences of the empty string within the string:

def strlen(s):
    return s.count('') - 1

Since "".count("") returns 1, you have to subtract 1 to get the string's length.
