Data Science and Machine Learning (Theory and Projects) A to Z - Pandas for Data Manipulation and Understanding: Pandas

The video tutorial explains the grading system using numeric values and demonstrates how to create and manipulate series objects in Python using pandas. It covers the use of explicit and implicit indices, slicing, and accessing data within series. The tutorial concludes with an introduction to dataframes, highlighting their utility for handling multi-dimensional data.
