Python3 - Deleting dirs after finishing a commando prompt

Question

I have a python script that ends with running a program (iexpress.exe) in a dos prompt.
The program that runs in dos prompt, uses a dir called workdir. After the program has finished in the dos prompt I would like python to delete the dir. I have just made a simple solution of putting a delay of 30sec:

time.sleep(30)
removeall(workdir)
os.rmdir(workdir)

But how should I do it, if python should delete the dir right after the process has finished?

Answer 1

Make the python program call the exe and not fall off the end

ie call the exe using subprocess.Popen

The when the exe finishes you are still in python

Answer 2

Thanks. It works fine
