It can be tricky to setup a complete Python development environment on Windows. The easiest way to setup is to use anaconda which has built-in Python (also comes with many packages by default such as nltk, numpy, etc.) and use an IDE with it.

1. Download and install https://www.anaconda.com/download/
2. Install Visual Studio code https://code.visualstudio.com/docs/setup/setup-overview
3. Download Visual Studio cheat sheet https://code.visualstudio.com/docs/getstarted/keybindings#_keyboard-shortcuts-reference
4. Install Python module for Visual Studio code https://code.visualstudio.com/docs/python/python-tutorial
5. Enable unittest (File > Preferences > Settings), this will open settings.json. Edit the right pane (USER SETTINGS) to something like this

// Place your settings in this file to overwrite the default settings
{
    "python.unitTest.unittestEnabled": true,
    "python.unitTest.pyTestEnabled": false,
    "python.unitTest.nosetestsEnabled": false
}

Using a local virtual environment (i.e. project_folder/environment_folder)
