5. Expressions

This chapter explains the meaning of the elements of expressions in Python.

Syntax Notes: In this and the following chapters, extended BNF notation will be used to describe syntax, not lexical analysis. When (one alternative of) a syntax rule has the form

  `name` | ::= | `othername`

and no semantics are given, the semantics of this form of `name` are the same as for `othername`.
