@ -1055,7 +1055,7 @@ The power operator binds more tightly than unary operators on its left; it binds
less tightly than unary operators on its right. The syntax is:
.. productionlist::
power: ( `await_expr` | `primary` ) ["**" `u_expr`]
power: (`await_expr` | `primary`) ["**" `u_expr`]
Thus, in an unparenthesized sequence of power and unary operators, the operators
are evaluated from right to left (this does not constrain the evaluation order

The shifting operations have lower priority than the arithmetic operations:

shift_expr: `a_expr` | `shift_expr` ( "<<" | ">>" ) `a_expr`
shift_expr: `a_expr` | `shift_expr` ("<<" | ">>") `a_expr`
These operators accept integers as arguments. They shift the first argument to
the left or right by the number of bits given by the second argument.
