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.

Python variables can also be assigned to the result of an expression. Variable Initialization Initialization is the process of assigning an initial value to a variable at the time of creation.
