Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:
Python's order of operations runs the exponentation before the unary minus. This convention makes the unary minus behave more like the subtraction operator so that: -x**n == 0 - x**n.
This convention is somewhat common but there are exceptions such as MS Excel where the unary minus binds first. See http://en.wikipedia.org/wiki/Order_of_operations#Examples
