python怎么實現(xiàn)冪函數(shù)

在python中利用遞歸實現(xiàn)一個冪函數(shù)，具體方法如下：

double PowerWithExponentUnsigned(double base, unsigned int exponentUnsigned)
{
// 最小子問題
if(exponentUnsigned == 0)
return 1;
double result = PowerWithExponentUnsigned(base,exponentUnsigned / 2);
result = result * result;
if(exponentUnsigned % 2 == 1)
{
result *= base;
}
return result;
}
