'str' does not support the buffer interface Python3 from Python2

Question

Hi have this two funtions in Py2 works fine but it doesn´t works on Py3

def encoding(text, codes):
    binary = \'\'
    f = open(\'bytes.bin\', \'wb\')
             


        

Answer 1

The fix was simple for me

Use

f = open('bytes.bin', 'w')

instead of

f = open('bytes.bin', 'wb') 

In python 3 'w' is what you need, not 'wb'.
