How do i watch python source code files and restart when i save?

Question

When I save a python source code file, I want to re-run the script. Is there a command that works like this (sort of like nodemon for node)?

Answer 1

You can install nodemon to watch for file changes.

e.g.

npm i -g nodemon

Then to use:

nodemon --exec python3 hello.py 

This is for when you use python3 in the command line. On windows you can also use 'py' instead.
