Python Expressions vs. Python Statements - CodingNomads
A statement is made up of components that can be other statements as well as expressions. Python Statement Example. An example of a statement is the variable assignment: x = 2 In this variable assignment, you're creating a reference between the variable x and the value 2. This statement doesn't have a computed result, contrary to an expression like the one shown further up. All you do is assign a value to a variable.
