Convert bytes to a string

Question

I\'m using this code to get standard output from an external program:

>>> from subprocess import *
>>> command_stdout = Popen([\'ls\', \'-l         


        

Answer 1

I think you actually want this:

>>> from subprocess import *
>>> command_stdout = Popen(['ls', '-l'], stdout=PIPE).communicate()[0]
>>> command_text = command_stdout.decode(encoding='windows-1252')

Aaron's answer was correct, except that you need to know which encoding to use. And I believe that Windows uses 'windows-1252'. It will only matter if you have some unusual (non-ASCII) characters in your content, but then it will make a difference.

By the way, the fact that it does matter is the reason that Python moved to using two different types for binary and text data: it can't convert magically between them, because it doesn't know the encoding unless you tell it! The only way YOU would know is to read the Windows documentation (or read it here).
