6.100L Introduction to CS and Programming Using Python
6.100L Introduction to CS and Programming Using Python (Fall 2022, MIT OCW). Instructor: Dr. Ana Bell. This subject is aimed at students with little to no programming experience. It aims to provide students with an understanding of the role computation can play in solving problems. It also aims to help students, regardless of their major, feel justifiably confident in their ability to write simple programs that allow them to accomplish useful goals. The class will use the Python 3 programming language.

Lecture 07 - Decomposition, Abstraction, and Functions
An introduction to functions and their decomposition, abstractions, and specifications. Functions allow us to suppress detail from a user and capture computation within a black box. A programmer writes functions with 0 or more inputs and something to return. A function only runs when it is called and the entire function call is replaced with the return value.
