Scope and namespaces in Python Problem Solving w/Python Ch 5 Lecture 4
Do you want to learn to code? If you're a beginner, you're in the right place! This video is part of an introductory series that will teach you to program in the popular Python programming language. In this video, we learn about scope or name visibility -- how Python resolves a name in a program to its meaning. It's important to understand this concept, or you'll have difficulty writing large-scale programs and understanding the errors that you will inevitably write into your programs if you're unfamiliar with scope. This series of videos is suitable for beginners or experienced programmers who want to learn Python. Let's have some fun learning to program with Python!
