Introductory Python 1-Hour Refresh

This video is a review of the introductory Python playlist content (Problem Solving with Python). It's a great choice if you're reviewing Python between semesters or refreshing your knowledge after time away from Python. The Problem Solving with Python series of videos is suitable for programmers with minimal (or no) programming experience who want to learn Python. In this review video, we begin with creating a script in IDLE and writing an input-processing-output program, then enhance the program through conditional statement, loops, functions, and files until we finally write a program that reads data from a text file into a list. These are the exercises for each part of the video*: Input-processing-output: https://codecheck.io/files/26010221531rqj2m5hfqx6r8n4rljhq7h0o Conditional (if): https://codecheck.io/files/2601031425ew761zw5d49bj78fxglyxq4oa While loops: https://codecheck.io/files/2601031437ap8uxbsqzf699ybzdl9syarqi Functions: https://codecheck.io/files/26010314466d8azpbbhae1t00lw9wmh9nlw Text file processing: https://codecheck.io/files/26010314562uykntad6zpngucj832m1turv Lists: https://codecheck.io/files/260103150386b79jxi0v93yww4794pmisqe Iterables 1: https://codecheck.io/files/2601031507d02mntcd3x7xvygr3txpk3t4z Iterables 2: https://codecheck.io/files/26010315127kz94v3m8jr2lg6h98pr10tia *The CodeCheck system courtesy of Cay Horstmann, https://horstmann.com/codecheck/ This is the entire Introductory Python playlist: https://www.youtube.com/playlist?list=PLTwy92rWKPiFWViO7DYFs0iY2cyoXIZ1Y This is the Adventures with Python playlist: https://www.youtube.com/playlist?list=PLTwy92rWKPiGwvZxnUDf7S0skAXkSxOtr This is the video on how not to write a while True loop: https://youtu.be/tKtTiYQfE_Q You can purchase the book that goes with this video series here, as an ebook: https://amzn.to/3oiWwOb Or textbook: https://www.barnesandnoble.com/w/problem-solving-with-python-margaret-stone-burke/1129539414?ean=9798986151311 The github repository with all of the code examples for the book and these videos is here: https://github.com/ProfessorBurke/PythonProblemSolving/tree/main/OneHourRefresh If you want to earn credit for learning to code, take an online course at CCRI!
