Convert bytes to ascii and back save in Python?

Question

I'm Using python 3.5

I have a couple of byte strings representing text that is encoded in various codecs so: b'mybytesstring' , now some are Utf8 encoded other are latin1 and so on. What I want to in the following order is:

• transform the bytes string into an ascii like string.
• transform the ascii like string back to a bytes string.
• decode the bytes string with correct codec.

The problem is that I have to move the bytes string into something that does not accept bytes objects so I'm looking for a solution that lets me do bytes -> ascii -> bytes safely.

Answer 1

x = x.decode().encode('ascii',errors='ignore')
