Loops can iterate over any sequence of values including a range for numbers or a string. Guess-and-check provides a simple algorithm for solving problems. When the set of potential solutions is enumerable, exhaustive enumeration is guaranteed to work (eventually). Binary numbers help us understand how the machine works. Converting to binary will help us understand how decimal numbers are stored License: Creative Commons BY-NC-SA More information at https://ocw.mit.edu/terms More courses at https://ocw.mit.edu Support OCW at http://ow.ly/a1If50zVRlQ We encourage constructive comments and discussion on OCW’s YouTube and other social media channels.

About the course

Instructor: Ana Bell View the complete course: https://ocw.mit.edu/courses/6-100l-introduction-to-cs-and-programming-using-python-fall-2022/ *Note: Lectures 6, 10 have been updated! 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, to 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.
