python - Attempting to Base64 encode this variable -


i'm trying encode 'username' variable base64, write text file, , decode base64, , read/print it. 

while true:  username = input("what username?: ")  file = open("newfile.txt", "w") file.write(base64.b64encode(username)) file.close  file = open("newfile.txt", "r") file.read(base64.b64decode(username)) break

-typeerror- 'str' not support buffer interface

what did here seemed logical out of i've seen.

i new python, , have tried method's i've seen online base64 encode variable, , none have worked.

base64 expects , returns bytes (in python3); strings must written files. here example explicit writing , more compact reading:

import base64  while true:      username_str = input("what username?: ")      open("newfile.txt", "w") file_handler:         username_bytes = bytes(username_str, 'utf-8')         b64_bytes = base64.b64encode(username_bytes)         b64_str = b64_bytes.decode('utf-8')         file_handler.write(b64_str)         # file_handler.close()         # close not needed inside context handler     open("newfile.txt", "r") file_handler:                 print(base64.b64decode(bytes(file_handler.read(), 'utf-8')).decode('utf-8'))     break

btw: file reserved keyword , should not used variable.
