First, install the Jupyter Notebook from https://jupyter.org/
After installing Python on your system, open the terminal and enter this command:
python(version_name) -m notebook
For me, it is-
python3.8 -m notebook
But If you want to create a specific folder, then into this folder you want to create the notebook
First enter to that folder like this cd /Users/mdtarif/Downloads

Then press Enter
A new page will open in your browser named like - http://localhost:8888/tree



Now don’t print Hello World! 🙄
It is so boring 🥱
Try something new 🥳
Print your name 😎
