Title: Executing Python Functions from the Command Line: A Step-by-Step Tutorial
Introduction:
Executing Python functions from the command line can be a powerful and efficient way to run specific tasks or scripts. In this tutorial, we will explore how to create a Python script that can be executed from the command line, taking arguments and invoking functions based on user input.
Step 1: Create a Python Script:
Let's start by creating a Python script that will contain the functions you want to execute. Save the following code in a file named script.py:
This script defines two functions, greet and multiply, and checks the command-line arguments to determine which function to execute.
Step 2: Run the Script from the Command Line:
Now, you can run the script from the command line. Open your terminal and navigate to the directory containing script.py. Use the following commands:
You can replace "World" and the numbers with your own arguments.
Conclusion:
By following this tutorial, you have learned how to create a Python script that can be executed from the command line, allowing you to invoke specific functions with arguments. This approach provides a flexible and convenient way to interact with your Python code, especially for tasks that require user input or parameterized execution.
