Table of Precedence and Associativity

This table shows the precedence and associativity of the arithmetic, relational, and logical operators from highest to lowest precedence.

Operation	Description	Associativity
`()`	parentheses for grouping	left to right
`**`	exponentiation	right to left
`+`, `-`	unary `+` (positive sign),	left to right
	unary `-` (negative sign)
`*`, `/`, `%`	multiplication, division, remainder	left to right
`+`, `-`	addition and subtraction	left to right
`in`, `not in`, `is`, `is not`,	membership and comparisons	left to right
`<`, `<=`, `>`, `>=`, `!=`, `==!`
`not`	boolean not	left to right
`and`	boolean and	left to right
`or`	boolean or	left to right

In Python 3, // (integer division) has the same precedence as *, /, and %.
