Episode 1 of #PythonLiveLessons, a weekly live stream about Python code (with live coding) and more, hosted by Sebastiaan Mathôt. In this episode, we'll continue working on our Python project, `markdown_code_exec`. We'll learn about the difference between expressions and statements, and the difference between eval() and exec(). At the end of this episode, we'll have a fully functional 'sketch' of our program, which we'll develop further in future episodes!
