I would assume the difference is caused by `ls` changing behavior (for
example, enabling/disabling colorization) based on whether its output
is going to a terminal or a pipe.
Is there a reason you can't use os.listdir() instead of running ls?:
For the colorization, google for "ANSI color escape sequences"
