One way you could do it is by using imports.

Lets say you have a python script called test.py, and you have an another called test2.py, you can import test2 into test.py and run it from there. Although they would have to be in the same directory.

In your case since the 4th script will be running the other three, it would be like this.

import my_prog1
import my_prog2
import my_prog3

The other way to do this is by using the os module

import os

os.system('python my_prog1')
os.system('python my_prog2')
os.system('python my_prog3')

Use the import keyword in the fourth Python file to import the files that you would want to run. It would run all the files.

import my_prog1
import my_prog2
import my_prog3

Make sure all the files, including the fourth file, is in the same directory, or else this won't work.
