1. The Lab (Setup)

Interactive Computing

Data Science is not Linear development; it is an exploration.

Jupyter Notebooks

Code + Markdown + Output in one file.

• Kernel: The Python process running in the background.
• Cell: A block of code.

bash
pip install jupyterlab
jupyter lab

Anaconda / Miniconda

Data libraries (NumPy, SciPy) can be hard to install. Conda manages binary dependencies for us.
