Hello!
it's Ok. Python gets from 1/2 0 as 0 is the integer part of that
division. So, Python is interpreting -1**0 so you get 1 as answer.
you should try this (-1)**(1.0/2.0) so 1.0/2.0 is an operation returning
0.5 completely.
and you'll get:
>>> (-1)**(1.0/2.0)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: negative number cannot be raised to a fractional power

Jesús (Neurogeek)
