How to install Jupyter lab

Jupyter lab is one of the most widely used Python IDE for Data Science.

Why?

Jupyter lab allows you to execute code snippets stored in cells instead of running the entirety of a Python script.

The kind of document Jupyter lab produces are called Jupyter notebooks (.ipynb).

This is extremely useful when performing exploratory analyses.

You don't need to re-run your script every time you make a change, you can just run the cell containing the change.

Another great feature of notebooks is the ability to add markdown text in cells so that you can enrich your Python script with images, titles, lists, links, etc...
