[notebook pre-load and pre-config] Script with commands that will be executed upon notebook initialization #notebook #jupyter

start.py

"""
If you often use interactive IPython sessions or Jupyter Notebooks and you’re getting tired of importing the same libraries over and over, try this:

Navigate to ~/.ipython/profile_default
Create a folder called startup if it’s not already there
Add a new Python file called start.py
Put your favorite imports in this file
Launch IPython or a Jupyter Notebook and your favorite libraries will be automatically loaded every time!
