数值的整数次方

题目描述：

给定一个double类型的浮点数base和int类型的整数exponent。求base的exponent次方。

答案：

# -*- coding:utf-8 -*-
class Solution:
def Power(self, base, exponent):
# write code here
value = base
if base == 0:
return False
if exponent > 0:
for i in range(1,exponent):
value = value*base
return value
elif exponent < 0:
for i in range(1,abs(exponent)):
value = value*base
return 1/value
