blocking a program until a non-Python process terminates

[Earl Eiland]

I'm running an .exe in Python, using subProcess.Pope n. The executable
writes data to a file I process later on in the program. Unfortunately,
my program returns the error "no such file...". How do I block
execution until the external executable terminates?

Either:

1)

returncode = subprocess.call (cmdline)

2) or:

pipe = subprocess.Pope n(cmdline)
returncode = pipe.wait()
