Check Yourself

What is a type?

Type are classifications of objects, which is what Python, as an OOP language, deals with. They determine how those objects are dealt with (for example, adding two integers results in an integer, two strings results in a concatenated string, and on integer and a string results in an error).

What is an 'expression'?

An expression is composed of objects (or operands) and operators, and can be interpreted into a value.
