How Can I Invoke A Function From A Different .py File Using Python?

To call a function from another Python file, you need to follow these steps:

  1. Import the module that contains the function you want to call by using the import keyword followed by the name of the file (without the .py extension). For example, if the file is named, use import other_file.

  2. To call the function from the other file, use the module name followed by a dot (.) and the function name. For example, if the function is named my_function in, use other_file.my_function().

Here’s an example that demonstrates how to call a function named hello from a file named

import other_file

def hello():
    print("Hello from other_file!")

When you run, it will import other_file and call the hello function defined within it, which will print "Hello from other_file!" to the output.
