Issue 10931: print() from pipe enclosed between {b'} and {'}-pair on python3 (original) (raw)

The following script produces different output on python2.6.6 vs. python3.1.2:

import subprocess, sys

ls = subprocess.Popen(['ls', '-l', '/etc/motd'], stdout=subprocess.PIPE,)

end_of_pipe = ls.stdout

print('Result:')

for line in end_of_pipe: print(line.strip())

Result from invoking with python2 and python3 are respectively:

Result: -rw-rw---- 1 root root 25 Jan 18 10:25 /etc/motd

and:

Result: b'-rw-rw---- 1 root root 25 Jan 18 10:25 /etc/motd'

Is this difference a feature, or a bug ?
