To ls, --color=auto indicates that the type of the output file descriptor
should be detected and colors included or elided depending on whether it
is likely that the output is being viewed by a human or a program.
Since you are running ls with popen, ls decides it is a program, and elides
the colors.
Try os.popen("ls --color=yes").
