  5.4 The power operator

  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:

        power    ::=     primary[1] ["**" u_expr[2]]

It seems to be case-sensitive Mr. Moores!
When I entered 'power' (like you did), I also got:
help> 'power'
no Python documentation found for 'power'

Try entering: 'POWER'  (all caps, just like in the output).

Happy Programming!
