How to execute a command in python file?

Question

Currently executing this in google colab:

!python myfile.py   --size 45  --file textfile.txt --data_folder somePath/folder

How can I put the above command into a python file (executeNow.py), so that I'll be able to run this in google colab:

!python executeNow.py

Namely what should be written inside execute.py so that the above to commands will be equivalent?

You can use the module subprocess for that. Put this in your executeNow.py:

import subprocess
subprocess.run(["python", "myfile.py", "--size", "45", "--file", "textfile.txt", "--data_folder", "somePath/folder"])

However, for this task I'd recommend using a bash script: write this into executeNow.sh:

#!/bin/bash
python myfile.py --size 45 --file textfile.txt --data_folder somePath/folder

Optionally, make that file executable:

!chmod +x executeNow.sh

Then run this in Colab:

!sh executeNow.sh

If you did the optional part, you can contract the above command slightly shorter:

!./executeNow.sh
