A Beginner's Guide to Running Python Scripts on Linux and Windows

In this guide, we walk through the steps required to run Python scripts smoothly on both Linux and Windows systems, helping beginners understand how to execute their programs efficiently across different environments.

How to Run Python Script?

Python is one of the most widely used programming languages, powering applications in web development, automation, data science, artificial intelligence, and many other fields. After writing a Python script, the next step is learning how to execute it correctly on your system.

Running a Python script usually involves using a command-line interface such as the Terminal on Linux or the Command Prompt on Windows. These tools allow developers to navigate to the location of their script and run it using the Python interpreter. Understanding this basic process is essential for beginners who want to test and run their programs efficiently.

In the following sections, we will explore how to run Python scripts on both Linux and Windows systems, along with a few practical tips that make script execution smoother across platforms.

Running Python Scripts on Linux

Linux provides a powerful command-line environment that makes running Python scripts simple and efficient. Most Linux distributions already include Python, which means developers can begin executing scripts without going through complex installation procedures.

Using the terminal, you can quickly navigate to the directory containing your script and run it with a single command. This streamlined workflow makes Linux especially popular among developers who rely on automation, scripting, and server-side development. The command-line interface also offers better control over environments, permissions, and dependencies, making it easier to manage Python projects and troubleshoot issues when they arise.

Open Terminal

On Linux, the terminal acts as the primary interface for interacting with the system and running scripts. Most developers prefer it because it provides direct access to commands and system tools. You can open the terminal by searching for Terminal in the applications menu of your Linux distribution. Many systems also support a quick keyboard shortcut such as Ctrl + Alt + T, which launches the terminal instantly.

Once opened, the terminal allows you to run commands, manage files, install software, and execute programming scripts, including Python programs.

Navigate to the Script Directory

After opening the terminal, the next step is to move to the folder that contains your Python script. This is done using the cd (change directory) command, which allows you to switch between directories in the file system.

For example, if your script is located in a specific folder, you can navigate to it using:

cd /path/to/your/script/directory

Replace the example path with the actual location of your Python file. Navigating to the correct directory ensures that the terminal can locate the script you want to execute.

Check Python Version

Before running the script, it is useful to confirm that Python is installed and accessible from the terminal. You can check the installed Python version using the following command:

python --version

This command displays the version of Python currently available on your system. Verifying the installation helps prevent errors and ensures the script will run with the expected Python interpreter.

Run the Script

After navigating to the correct directory and confirming that Python is installed, you can execute the script using the Python interpreter. Running the script is done with a simple command:

python your_script.py

Replace your_script.py with the name of your actual Python file. Once the command is executed, Python will run the script and display any output directly in the terminal window.

This simple command-line approach allows developers to quickly test, debug, and execute Python programs in a Linux environment.

Running Python Scripts on Windows

Windows users can run Python scripts using the Command Prompt, which works as a command-line interface similar to the Linux terminal. It allows you to execute commands, navigate directories, and run programs such as Python scripts directly from the system shell.

Using the Command Prompt is one of the most straightforward ways to execute Python files, especially during development or testing. Once Python is installed and configured correctly, running a script typically requires only a few simple commands.

Open Command Prompt

To begin, open the Command Prompt on your Windows system. You can do this by searching for Command Prompt in the Start menu and selecting it from the results.

Another quick method is to press Win + R, type cmd, and press Enter. This will immediately launch the Command Prompt window, allowing you to start entering commands.

Navigate to the Script Directory

After opening Command Prompt, you need to move to the directory that contains your Python script. This can be done using the cd (change directory) command.

cd C:\path\to\your\script\directory

Replace the example path with the actual location of the folder where your Python script is stored. Navigating to the correct directory ensures that the system can locate and run your script.

Check Python Version

Before running the script, it is helpful to verify that Python is installed and accessible through the command line. You can check this by running the following command:

python --version

This command displays the installed Python version. If the version appears correctly, it confirms that the Python interpreter is properly installed and configured on your system.

Run the Script

Once you are in the correct directory and have confirmed that Python is installed, you can run your Python script using the Python interpreter.

python your_script.py

Replace your_script.py with the name of your actual Python file. After executing the command, Python will run the script and display any output directly in the Command Prompt window.

This method allows Windows users to quickly test, execute, and debug Python programs using a simple command-line workflow.

Tips for Running Python Scripts on Both Platforms

Running Python scripts on both Linux and Windows becomes much easier when you follow a few practical best practices. While the basic process of executing scripts is similar on both systems, small differences in environment setup, permissions, and dependency management can affect how smoothly your scripts run.

By organizing your projects properly and using built-in Python tools, you can ensure that your scripts run consistently across different operating systems.

Virtual Environments

Virtual environments are an important part of managing Python projects. They allow you to isolate project dependencies so that libraries installed for one project do not interfere with those used in another.

Python provides a built-in module called venv that makes it easy to create lightweight virtual environments for individual projects. By using virtual environments, developers can maintain clean project setups and ensure that the correct versions of packages are installed for each application. This approach also makes it easier to share projects with others without causing dependency conflicts.

Shebang Line

In Linux-based systems, you can add a shebang line at the beginning of a Python script to specify which interpreter should be used to run the file.

#!/usr/bin/env python

This line tells the operating system to locate the Python interpreter in the system environment and execute the script using it. When a shebang line is included, you can run the script directly without needing to type the Python command every time. This is especially useful when working with executable scripts or automation tasks on Linux servers.

File Permissions

Unlike Windows, Linux systems require executable permission for scripts that are intended to run directly. If the script does not have the correct permissions, the system will prevent it from executing.

You can grant executable permission using the chmod command in the terminal.

chmod +x your_script.py

After applying this permission, the script can be executed like a regular program from the command line. Managing file permissions correctly is an important step when running scripts in Linux environments, especially when working with automation, scheduled tasks, or deployment scripts.

Conclusion

Running Python scripts on Linux and Windows is a straightforward process that mainly involves navigating to the script location and executing it using the Python interpreter. Once you become comfortable with the command-line environment, running and testing Python programs becomes quick and efficient.

By understanding the basic steps outlined in this guide and following best practices like using virtual environments and proper file permissions, developers can execute Python scripts smoothly across different operating systems and maintain a more organized development workflow.

As you continue building Python applications, mastering basic execution methods across platforms becomes an essential skill. It allows developers to test code efficiently, automate tasks, and deploy scripts in different environments with confidence. With these fundamentals in place, working with Python becomes smoother, more structured, and far more productive.
