The Python programming language contains basic elements for specifying instructions. When a Python instruction is executed, the interpreter processes the instruction as a command, which is telling the processor what action it needs to perform. Some basic commands include assigning a value to a variable, adding two values together, and, as we saw in our first Python program in Chapter 1, printing a message to the console for a user to read. In order for the interpreter to operate efficiently, a limited number of basic elements are used to specify instructions. This section briefly introduces elements, including Python keywords, objects and classes, operators and delimiters, data types, and variables.
