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 other_file.py, 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 other_file.py, use other_file.my_function().

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

# main.py
import other_file

other_file.hello()
# other_file.py
def hello():
    print("Hello from other_file!")

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