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 14 - Dictionaries
Introduces dictionaries, their keys and values, their mutability, and iteration over a dictionary with examples. Dictionaries have entries that map a key to a value. Keys are immutable/hashable and unique objects while values can be any object. Dictionaries can make code efficient implementation-wise and runtime-wise.
