Install Jupyter notebook
Why Jupyter notebook?
Jupyter is built on the IPython project and allows for interactive python to be run in your browser. But it is so much more than that. From bash commands to special “magic” and “plugins”, Jupyter enhances the Python coding experience greatly.
Steps for Installation
Step1: To install Jupyter notebook, simply go to command prompt and type “pip install Jupyter”.
Step 2: After installation, start your notebook by running “Jupyter notebook” in your working directory via command prompt.
Typically Jupyter will open automatically once it starts up, but if not, point your browser over to localhost:8888.
Below is the screenshot of how Jupyter notebook initialized in the browser.
