How to Import and Call a Function from a Separate Python File?

How to Call a Function from a Different Py File

When working with multiple Python files, it's often necessary to import functions from one file into another. However, issues can arise if the imported file's name collides with a built-in Python module, as demonstrated in the example code.

file.py contains a function named function. How do I import it?

from file.py import function(a,b)

This code throws an "ImportError: No module named 'file.py'; file is not a package" error because "file" is a core Python module. To resolve this issue, follow these steps:

1. Import the function from the file module:

from file import function

2. Call the function using:

function(a, b)

Ensure that both the exporting and importing files are in the same directory for successful function import.

Alternatively, if you're encountering the same issue with a different file name (e.g., a.py and b.py), place both files in the same directory and use the following code:

import a
a.function(a, b)
