I can't get this code, please help!

I can't understand how this code works and why is the input is 42 the output is 2, if you can give me any help I'll be grateful n = int(input()) length = 0 while n > 0: n //= 10 length += 1 print(length)

Hello Néstor Velandia while 42 > 0 -> True 42 // 10 = 4 length = 1 while 4 > 0 -> True 4 // 10 = 0 length = 2 while 0 > 0 -> False In general this code counts the number of digits. 42 -> 2 digits -> length = 2 312 -> 3 digits -> length = 3
