Factorials and Functions in Python

This video tutorial introduces the concept of factorials and demonstrates how to calculate them using Python. The instructor sets up a function to compute factorials, explains the logic behind it, and executes the function with examples. Debugging techniques are also shown. The video concludes with a hint about using recursion for factorials, which will be covered in the next video.
