Python for Data Analysis: Step-By-Step with Projects - Making a Copy

The video tutorial explains how to create copies of data frames in Python, emphasizing the difference between creating a reference and a true copy using the copy method. It demonstrates how modifications to a reference affect the original data frame, while changes to a true copy do not. The tutorial also covers verifying data frame relationships using the 'is' operator, highlighting the importance of using the copy method to maintain data frame independence.
