5.14 Summary
</H1>

<P>
The following table summarizes the operator
precedences<a id='l2h-450' xml:id='l2h-450'></a> in Python, from lowest
precedence (least binding) to highest precedence (most binding).
Operators in the same box have the same precedence.  Unless the syntax
is explicitly given, operators are binary.  Operators in the same box
group left to right (except for comparisons, including tests, which all
have the same precedence and chain from left to right -- see section
<A href="comparisons.html#comparisons">5.9</A> - and exponentiation, which groups from right to left).

<P>
