The Core Concept
Before writing Python code on your computer, you need two things: the interpreter and a code editor. The interpreter reads your code, and the editor is where you type it. We recommend using Python 3 and Visual Studio Code (VS Code), which is free and highly customizable.
During installation on Windows, the most important step is checking the box that says 'Add Python to PATH'. If you miss this, your system won't recognize the 'python' command in your terminal, leading to frustrating 'command not found' errors. Once installed, we will verify the setup using the command prompt.

Code & Implementation
# Verify Python installation in your terminal
python --version
# Verify pip (Python Package Installer) installation
pip --versionExpected Output
Python 3.12.2 pip 24.0 from ... (python 3.12)

The Challenge
Launch your terminal or command prompt, successfully output your Python version, and write a one-line command to open Python in interactive mode.
Helpful Hints
- •To enter interactive mode, just type python (or python3) and press Enter.
- •You will see triple greater-than signs (>>>) where you can type Python commands directly.
- •To exit interactive mode, type exit() and press Enter.
