What is the difference between using codecs.StreamReader and io.TextIOWrapper on a binary stream?

#!/usr/bin/env python3

import codecs
import io

stream = io.BytesIO(b'abc')
#reader = codecs.getreader('utf-8')(stream)
reader = io.TextIOWrapper(stream)
print(reader, reader.read())

Why would you create a bytes-like object/stream and then feed it to `TextIOWrapper`? – wwii Jan 16 '19 at 23:48
@wwii This is just an example. But to answer your question, when someone else gives you a bytes-like stream. – Cyker Jan 16 '19 at 23:50
codecs works in Python 2 and 3? ... https://stackoverflow.com/a/34511829/2823755 – wwii Jan 17 '19 at 00:13
@wwii Python 2 no longer exists. – Cyker Jan 17 '19 at 00:15
No legacy code for you then. – wwii Jan 17 '19 at 00:18
@wwii Yeah. I have already upgraded. – Cyker Jan 17 '19 at 00:19
