In Python, a dictionary is similar, but instead of having words and their meanings, they have a variable and another one associated with that variable.

Python is a dynamically-typed language, which means if you try to mix variables that have different data types, it usually finds a way to resolve the difference or raises an exception if it can’t.

Ubuntu is a free computer system, like Windows or macOS, but it’s built by a community. It’s great for programmers because it’s very flexible and has lots of tools already built-in that help you code.
