🐍 How to Run Multiple Python Versions on Windows 🖥️

Are you facing the issue of having multiple Python versions installed on your Windows machine and not being able to choose the one you want to use for different projects? 🤔 Don't worry, I've got you covered! In this guide, I'll show you how to specify which Python version you want to run on your Windows XP SP2. Let's dive right in! 💪

Common Issue: Running Multiple Python Versions

So, you have Python 2.6 and Python 2.5 installed on your Windows machine, and you want to use each version for different projects? The problem is that simply running "python" in the command prompt will execute the default Python version, which may not be the one you desire. 🤷‍♂️

Solution: Using Python Launcher for Windows

To overcome this issue, you can utilize the Python Launcher for Windows, also known as py. Follow these steps to run multiple Python versions with ease:

1. Open the command prompt by pressing Win + R and typing cmd in the Run dialog. Hit Enter to open the command prompt window.

2. To check if the Python launcher is already installed, type py -0 in the command prompt and press Enter. If you see a list of installed Python versions, you're good to go! If not, you'll need to install it.

3. If the Python launcher is not installed, download the latest version of Python for Windows from the official Python website and install it.

4. Once the Python launcher is installed, you can specify the Python version you want to use by prefixing your script's command with py -<version>. For example, to run a script using Python 2.6, you would use py -2.6 my_script.py. Similarly, for Python 2.5, you would use py -2.5 my_script.py.

Now you can easily switch between Python versions for different projects without any hassle! 🎉
