Getting Started with the JupyterLab 3 IDE (Windows)

JupyterLab is one of the most popular IDEs for data science due to its capabilities to create text files, markdown files, create Python Script Files run Python code. Finally it bridges all of these capabilities with an Interactive Python Notebook.
In this video I install the latest version of the JupyterLab 3 IDE, Python 3.11 and the Scientific Python Libraries in a Python Environment using Mambaforge on Windows 11 (22H2). Mambaforge is used in preference to Anaconda, because the Anaconda channel is outdated compared to the community channel.

Thank you. I followed step by step for the Mamba forge and JupyterLab. I wish there is more eegant way to start the JupyterLab

[@philipyip1988]

Great, glad you found it helpful. Yeah it's a shame there is no start menu shortcut to it but you get used to launching it from the Mambaforge prompt.

What a palaver! There must be something simpler than this!

[@kisho2679]

how can the headings be numbered automatically, and its order be changed with its content be shifted to other places in the document?

[@kisho2679]

how can mathematical commutative diagrams be drawn?
