What You'll Learn

An introduction to programming using a language called Python. Learn how to read and write code as well as how to test and "debug" it. Designed for students with and without prior programming experience who'd like to learn Python specifically. Learn about functions, arguments, and return values (oh my!); variables and types; conditions and Boolean expressions; loops; and objects and methods. Plus exceptions, file I/O, and libraries. Hands-on opportunities for lots of practice. Exercises inspired by real-world programming problems.

Whereas CS50x itself focuses on computer science more generally as well as programming with C, Python, SQL, and JavaScript, this course, aka CS50P, is entirely focused on programming with Python. You can take CS50P before CS50x, during CS50x, or after CS50x. But for an introduction to computer science itself, you should still take CS50x!

The course will be delivered via edX and connect learners around the world. By the end of the course, participants will understand the following concepts:

  • Functions, Variables
  • Conditionals
  • Loops
  • Exceptions
  • Libraries
  • Unit Tests
  • File I/O
  • Regular Expressions
  • Object-Oriented Programming
