Fixing base64 encoding error in Python 3.7

Question

I'm trying to access an API which has requires authentication. However I keep getting the error which reads " a bytes-like object is required, not 'str' " for the base64encode line.

user = input("user: example")
password = getpass.getpass("password: example1234")
authCred = base64.b64encode(user + ":" + password)

I tried to change the code to:

user = input("user: example")
password = getpass.getpass("password: example1234")
authCred = base64.b64encode(user.encode('ascii') + ":" + password.encode('ascii')).decode('ascii')

But then I get the error "can't concat str to bytes"

Does anyone know how I can fix this?

were you able to fix this?

Your attempted fix didn't work because you tried to mix encoded and non-encoded strings.

Make a string that is the username plus a colon plus the password, then encode that whole string:

userpass = user + ":" + pass
authCred = base64.b64encode(userpass.encode('ascii'))

Alternately, use b':' for the colon when assembling the results afterwards.

does encoding it as bytes help?

authcred = bytes(authcred , encoding= 'utf-8')
