Python interview question #6: Global vs. local variables

Python scoping -- which variable exists, and is available, at each point in time -- seems clear and obvious. But for many, it's incredibly confusing. If you're going to be interviewed for a Python job, then they might ask you to explain scoping... so, can you?

In this video, I explain the difference between local and global variables, as well as "builtins," and how they interact. You'll also learn what the "global" declaration does in a Python function.
