Why? Why not use os.rename or shutil.move which already do
whatever is needed under the covers for different Operating Systems?

os.popen returns a file-like object from which you can read any
error messages generated. You're not doing that, and os.popen
won't raise an error itself unless you, say, pass it a number
rather than a string.

<code>
import os

output = os.popen ("dir")
print output.read ()

#
# But note:
#
os.popen ("Nonsen*se")

# raises no exception

</code>
