I'm trying to convert a bytearray to and from a string. Why does the following not work? The encode seems to add an extra slash. Am I using the wrong encoding? I'm using python3.6
In [19]: b'\x88'.decode('unicode_escape') Out[19]: '\x88' In [20]: '\x88'.encode('unicode_escape') Out[20]: b'\\x88' When to use raw_unicode_escape mode
The backslash character is escaped so is written as \\. If you don't want that try the 'raw_unicode_escape' codec.
In the editor here, when answering your question, if I write \\ you see \ in the response so I actually had to write \\\\. Try it yourself to see what I mean (or edit this answer to see what I mean).
This is what I actually had to write above

You are using here bytes not bytearray So, if you want to encode and decode keeping the '\x', you can use
'\x88'.encode('raw_unicode_escape') b'\x88'.decode('unicode_escape') If what you have is a single value bytearray like this:
barray = bytearray([0x88]) you can get the string of this byte this way:
s = format(barray[0], '02x')
