Effortlessly Run a Python Script

How to Run Your Python Scripts and Code

A Python script or program is a file containing executable Python code. Being able to run Python scripts and code is an essential skill for Python developers. It allows you to test and debug your code to ensure it works as intended. In this tutorial, we will explore different techniques for running Python scripts and code depending on your environment, platform, needs, and skills.

What Scripts and Modules Are

In computing, a script is a text file that contains a sequence of commands or instructions to accomplish a specific task. In the context of Python, a script is written in the Python language and can be executed using a Python interpreter. These scripts allow you to manipulate, customize, and automate tasks.

Scripts in Python are typically interpreted at runtime rather than compiled. This means that they are executed by an interpreter, which interprets the code line by line.

How to Run Python Scripts From the Command Line

Running Python scripts from the command line is a straightforward and common way to execute Python code. There are several ways to do this:

  • Using the python Command: You can run a Python script by calling the python command followed by the script’s filename. This method allows you to execute scripts directly without any additional options.

  • Using the Script’s Filename Directly: If you make your Python script executable and include a shebang line at the top of the script, you can run the script by simply typing its filename. This method is convenient as it eliminates the need to explicitly call the python command.

  • Running Modules With the -m Option: Python modules can also be executed directly from the command line using the -m option. This is useful when you want to run a specific module and access its functions or variables.

How to Run Python Code Interactively

The Python interpreter provides an interactive mode that allows you to execute code snippets line by line. This is useful for testing and experimenting with small pieces of code. To use the Python interpreter interactively, you can open a terminal or command prompt and type python to start the Python interpreter.

Once in the interactive mode, you can enter Python code and see the results immediately. This can be helpful for exploring the behavior of different Python functions and modules.

How to Run Scripts From Python Code

Python provides several ways to run scripts from within other Python code. This is useful when you want to incorporate the functionality of an existing script into a larger program or automate certain tasks.

  • Taking Advantage of import Statements: By using import statements, you can import and run functions or classes from other Python scripts. This allows you to reuse code and call specific functions or execute certain tasks within your script.

  • Using the importlib Standard-Library Module: The importlib module provides more flexibility and control over the import process. It allows you to dynamically load and run Python modules, giving you more flexibility in managing dependencies and executing scripts.

  • Leveraging the Power of the Built-in exec() Function: The exec() function allows you to dynamically execute Python code at runtime. This can be useful when you need to run dynamically generated code or scripts.

How to Run Python Scripts on IDEs and Code Editors

Most integrated development environments (IDEs) and code editors provide built-in support for running Python scripts. These tools typically have dedicated run buttons or commands that allow you to execute your code within the IDE or editor.

IDEs and code editors often provide features like debugging, code highlighting, and code completion, making it easier to write and test Python scripts. Some popular IDEs and code editors for Python include PyCharm, Visual Studio Code, and Sublime Text.

How to Run Python Scripts From a File Manager

Apart from running Python scripts from the command line or within an IDE, you can also execute them directly from your operating system’s file manager. This method is useful when you want to run scripts by double-clicking on the file itself or using the context menu options.

To run a Python script from a file manager, you will need to associate the .py file extension with the Python interpreter in your operating system settings. Once the association is set up, you can simply double-click on the script to execute it.


Running Python scripts and code is crucial for Python developers to test and execute their programs. In this tutorial, we explored various techniques for running Python scripts, including using the command line, running code interactively, executing scripts from other Python code, and running scripts on IDEs and code editors.

By understanding and utilizing these methods, you will be able to effectively run and test your Python scripts in different environments, enhancing your productivity and efficiency as a Python developer.
