Machine Learning: Random Forest with Python from Scratch - Using Pandas for Random Forest (1)

This video tutorial introduces the Pandas library in Python, explaining its importance for data manipulation. It covers importing Pandas and Numpy, creating and viewing DataFrames, and manipulating them by adding or removing columns and rows. The tutorial also demonstrates how to locate specific data using loc and iloc functions. The session concludes with a brief mention of conditional selections in Pandas, to be covered in the next lecture.
