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
