I am working on problem set 2 and as a part of the function evaluate_poly I am testing a way to get the right exponent but when I test this piece of code x stays at 1 and I'm not understanding the reason.

poly = (1,2,3,4,5,6,7)
x = 2
for n in range(0,len(poly)):
x = x**n
print x

This is my code and when I run it, it prints
1
1
1
1
1
1

How do I get this to produce the right x, as in x to the power of n?

p.s. when I print n I get the values that I want as in
0
1
2
3
4
5
6

Just figured it out. I was changing the value of variable x from 2 to 1 on the first iteration because anything to the power of 0 is 1 and then from that point on 1 to the power of any number equals 1.
