How to import modules from py files

Question

So I received three python files with some functions. It's an util library provided by a third party. When I want to import these in my python file I use this code (as was specified by the third party):

import util.submission as S
import util.vis as V
import util.metrics as M

But then I get this error. I am working in Google Colaboraty and I uploaded the three python files in my current working directory on google colab so I don't understand. How do I fix this? The three files are just named submission.py ; vis.py and metrics.py. Any help here? This should be quite basic but it doesn't seem to work.

      3 import util.vis as V
      4 import util.metrics as M

ModuleNotFoundError: No module named 'util'

I believe to use `import x.y`, the .py's must be in a folder named `x`, or in this case, `util`. — clubby789, Oct 06 '19 at 12:59

`from utils import submission as S` etc. if the files are in a folder called util. If they are in the WD its `import submission. as S` — Alexander, Oct 06 '19 at 13:03

Create a folder in your current working directory named utils, and place the three .py files inside of it. You can then use the import statements as you have specified.
