Python3 - Import another Python file in Linux from user directory

Question

I have a python file running on /home/app that needs to import a python script from:

/home/app2/

At the top of my file I have:

import app2
sys.path.insert(1, '/home/app2/')

However when running the script I get:

No module named app2

Is there something I am doing wrong? The name of the class I want to import is called {app2} in this case

I am using Python 3.8 on Ubuntu 20.04

Answer 1

Okay I just created the files and folders /home/app/test.py and /home/app2/test2.py .

Within /home/app/test.py I have the following:

def test():
    print('working!')

And within /home/app2/test2.py I have:

from sys import path
path.insert(1, '../app/')
import test

test.test()

Which then prints working! . So the trick is:

from sys import path
path.insert(1, '../app/') # Can use absolute paths here if desired

Answer 2

When you add /home/app2 to your path, the interpreter is looking there for the module you're trying to import. In the case of your example, it's looking in /home/app2 for...app2. Try this instead:

sys.path.insert(1,'/home')
import app2
