How do I convert a Python 3 byte-string variable into a regular string

Question

I have read in an XML email attachment with  bytes string part get payload decode False    The payload comes in as a byte string  as my variable name suggests   I am trying to use the recommended Python 3 approach to turn this string into a usable string that I can manipulate   The example shows    str b abc   utf-8      How can I apply the b  bytes  keyword argument to my variable bytes string and use the recommended approach   The way I tried doesn t work   str bbytes string   utf-8

UPDATED   TO NOT HAVE ANY b and quotes at first and end How to convert bytes as seen to strings  even in weird situations   As your code may have unrecognizable characters to  utf-8  encoding  it s better to use just str without any additional parameters  some bad bytes   b  x02- xdfI    text   str  some bad bytes   2 -1   print text   Output   x02- xdfI  if you add  utf-8  parameter  to these specific bytes  you should receive error  As PYTHON 3 standard says  text would be in utf-8 now with no concern

You had it nearly right in the last line  You want  str bytes string   utf-8     because the type of bytes string is bytes  the same as the type of b abc
