If len(list) is not divisible by 3, then exclude last item in a function . Python 2.7.1

Question

if you have a string

string='abcdefg'

and you wanted to check if the length of the string is divisible by 3

len(string)

what command would you use?

Answer 1

You can use the modulo (division remainder) operator %:

if len(s) % 3 == 0:
    ...

If you want to strip the string to a length divisible by 3, use

s[:len(s) // 3 * 3]

or

s[:-(len(s) % 3)]
