UPDATE: In order to use reload in Python 3, it must be imported from the imp built-in module. Thus, some of the examples below will require the line from imp import reload in order to work in Python 3.
I’ve been mulling over an idea for a little while now, but didn’t have the chance to do anything with it until today. Turns it it was way easier than I thought it would be. For reasons I won’t go into here, I wanted to have a Python program which could write and run other Python programs. Clearly Python can write programs (since it can save text as a .py file), and it can easily run programs just by importing a module. The trouble was editing those files and running the updated code in the master program without having to restart the master program. Here’s how I did it.
