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

For Python 3, this is a much safer and Pythonic approach to convert from byte to string:

def byte_to_str(bytes_or_str):
    if isinstance(bytes_or_str, bytes): # Check if it's in bytes
        print(bytes_or_str.decode('utf-8'))
    else:
        print("Object not of byte type")

byte_to_str(b'total 0\n-rw-rw-r-- 1 thomas thomas 0 Mar  3 07:03 file1\n-rw-rw-r-- 1 thomas thomas 0 Mar  3 07:03 file2\n')

Output:

total 0
-rw-rw-r-- 1 thomas thomas 0 Mar  3 07:03 file1
-rw-rw-r-- 1 thomas thomas 0 Mar  3 07:03 file2
