如何从另一个python文件运行一个python文件？

Question

To start off, I am a beginner in python so I am not even sure if my question makes sense or is even possible.

I have 2 python files app.py . and compare.py . compare.py takes in two arguments (File paths) to run. So for example, when I want to run it, I do python compare.py ./image1.jpg ./image2.jpg . Now the return I get is some text printed to the terminal such as Comparison Done, The distance is 0.544 .

Now, I want to run this compare.py from inside app.py and get a string with whatever compare.py would usually output to the terminal. So for example:

result = function('compare.py ./image1.jpg ./image2.jpg') and result will have the required string. Is this possible?

Answer 1

You can use os.popen :

In app.py:

import os
output = os.popen('python compare.py ./image1.jpg ./image2.jpg').readlines()
