Since you specified os.P_NOWAIT in the spawnl() call, it didn't return
an exit code, but rather the process ID of the spawned process.  If
you were expecting the exit code, you should be using os.P_WAIT.

Other than that, we could really use more detail to help us answer
this question.  What exactly did the system do and print when you made
the call?  What did you expect/want it to do?
