This lecture discusses the core elements of programs: strings, input/output, f-strings, operators, branching, and indentation. Big idea: Debug early, debug often. Write a little and test a little. Don’t write a complete program at once. It introduces too many errors. Use the Python Tutor to step through code when you see something unexpected!
