Guide: Running a Python Script on a New Computer

Follow these steps to run your Python script on a new computer:

1. Install Python

   • Download and install Python v3 from python.org
   • Ensure you check "Add Python to PATH" during installation

2. Set up a virtual environment (recommended)

   • Open a terminal or command prompt
   • Navigate to your project directory
   • Create a virtual environment:

     python -m venv myenv
     

   • Activate the virtual environment:
     • On Windows:

       myenv\Scripts\activate
       

     • On macOS and Linux:

       source myenv/bin/activate
       

3. Install dependencies

   • If you have a requirements.txt file:

     pip install -r requirements.txt
     

   • If not, install required packages individually:

     pip install package_name
     

4. Transfer your script

   • Copy your Python script file(s) to the new computer
   • Place them in your project directory

5. Configure environment-specific settings

   • Set any necessary environment variables
   • Update file paths in your script if needed

6. Run the script

   • In the terminal, with your virtual environment activated, run:

     python your_script.py
     

Remember to deactivate your virtual environment when you're done:

deactivate

This process ensures that your script runs in an isolated environment with all necessary dependencies, regardless of the system-wide Python setup on the new computer.
