12. The value of the integer power

problem:

Given a double base type and floating-point type int integer exponent. Seeking exponent of the power base.
Ensure the base and exponent are not simultaneously 0

solve:

thought:

The main idea of ​​this question is that we must be clear how much power a number, this number is multiplied by itself is equivalent to many times.

python code

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