I will continue from where I left. If you haven’t seen part 2. Please visit https://medium.com/analytics-vidhya/getting-started-with-data-science-with-python-part-2-e3cc3411ac70. Because it will help you to understand.

Let’s go.

  1. Open jupytier notebook.
  2. Import pandas
  3. Load the CSV dataset into dataframes.
