How do I set up a Python virtual environment in VSCode using requirements.txt?

To set up a Python virtual environment in VSCode using requirements.txt, follow these steps:

1. Open your terminal in VSCode.
2. Navigate to your project directory.
3. Run python -m venv venv to create a virtual environment named 'venv'.
4. Activate the virtual environment:
   • On Windows: .envin\activate
   • On macOS/Linux: source venv/bin/activate
5. Install the required packages using pip install -r requirements.txt.

What if I don't have a requirements.txt file?

If you don't have a requirements.txt file, you can create one by running pip freeze > requirements.txt after installing the packages you need. This command will list all installed packages and their versions into the file.

Can I use a different name for my virtual environment?

Yes, you can name your virtual environment anything you like. Just replace 'venv' in the command python -m venv venv with your desired name.

How do I deactivate the virtual environment?

To deactivate the virtual environment, simply run the command deactivate in your terminal.
