How To Run Python Script Without Python Installed

In this tutorial, we will discuss how to run Python scripts on a system without Python installed. This process can save time and resources, especially when sharing your script with others who may not have Python installed on their computers.

We will cover two approaches: creating an executable using PyInstaller and using a standalone environment like Portable Python.


Before starting this tutorial, ensure you have the following:
– Familiarity with Python and running Python scripts.
– A Python script file (.py) you want to convert into an executable or run without Python installed.

Method 1: Creating an Executable using PyInstaller

PyInstaller is a powerful, cross-platform tool that can convert your Python script into an executable file. This file can be run on systems without Python installed because it bundles Python with your script.

Step 1: Install PyInstaller

To install PyInstaller, open a command prompt or terminal and run the following command:

This command will install PyInstaller on your system.

Step 2: Convert Python Script to Executable

To convert your Python script file to an executable, use the following command in your command prompt or terminal:

Replace “” with the name of your Python script file. The –onefile flag ensures the compilation of your Python script into a single executable file.

After running the command, PyInstaller will create a folder named “dist” with the executable file inside. The name of the executable will be the same as your Python script without the .py extension.

Step 3: Share and Run the Executable

You can now share the generated executable with others, and they will be able to run it on their systems without the need to install Python.

Method 2: Running Python Script using Portable Python

Portable Python is an environment that allows you to run Python scripts without installing Python on your system. It can be installed on a USB drive or other portable devices, so you can easily share your Python scripts with others.

Step 1: Download Portable Python

Visit the Portable Python website and download the latest version for your operating system.

Step 2: Extract and Set Up Portable Python

Extract the downloaded archive to a folder or external drive. In the extracted folder, you will find the Portable Python executable.

Double-click the executable to set up the environment. Follow the on-screen prompts to complete the installation.

Step 3: Running Python Scripts in Portable Python

After setting up the environment, you can run your Python script by double-clicking on the script file and selecting the Portable Python executable as the default program to open the script. It will run your script without requiring Python to be installed on your system.

Alternatively, you can open a command prompt or terminal from within the Portable Python folder. In the command prompt or terminal, run the following command:

Replace “” with the name of your Python script file.


In this tutorial, we have covered two methods for running Python scripts without installing Python on your system: creating an executable using PyInstaller and using Portable Python. Choose the method that best suits your needs and requirements. Remember to always test and debug your scripts thoroughly before sharing them with others. Happy coding!
