TypeError: 'str' does not support the buffer interface

Question

plaintext = input(\"Please enter the text you want to compress\")
filename = input(\"Please enter the desired filename\")
         


        

Answer 1

You can not serialize a Python 3 'string' to bytes without explict conversion to some encoding.

outfile.write(plaintext.encode('utf-8'))

is possibly what you want. Also this works for both python 2.x and 3.x.
