command line args in subprocess.call while executing a python script

Question

I've a python script which takes one command line argument as input from console. Now i want to run the script from a GUI button. The problem is i can't change the code because it's tedious

How can it be done in a easier way? I tried something like this:

subprocess.call(['./myScript.py args'])

but I can't see any output

Answer 1

You should specify command line argument as separated items:

subprocess.call(['./myScript.py', 'args'])

NOTE if your myScript.py runs long, that could cause UI hang because subprocess.call wait the process to terminate. Consider using subprocess.Popen that does not wait the termination.
