题目：

C++：

#include <stdlib.h>
#include <stdio.h>
#include <map>
#include <vector>
#include <string>
#include <math.h>
#include <algorithm>
#include <iostream>
#include <exception>
#include <stdexcept>
using namespace std;
//Write your code here
class Calculator {
public:
int power(int n, int p) {
if (n < 0 || p < 0) {
throw runtime_error("n and p should be non-negative"); //抛出异常
}
int ans = pow(n,p);
return ans;
}
};
int main()
{
Calculator myCalculator = Calculator();
int T, n, p;
cin >> T;
while (T-- > 0) {
if (scanf("%d %d", &n, &p) == 2) {
try {
int ans = myCalculator.power(n, p);
cout << ans << endl;
}
catch (exception& e) {
cout << e.what() << endl;
}
}
}
system("pause");
return 0;
}

python：

#Write your code here
class Calculator():
def power(self,n,p):
if n<0 or p<0:
raise RuntimeError("n and p should be non-negative")  #抛出异常
else:
ans=n**p
return ans
myCalculator=Calculator()
T=int(input())
for i in range(T):
n,p = map(int, input().split())
try:
ans=myCalculator.power(n,p)
print(ans)
except Exception as e:
print(e)

总结：

C++：

抛出异常，throw runtime_error()：

throw runtime_error("n and p should be non-negative"); //抛出异常

python：

抛出异常，raise RuntimeError()：

raise RuntimeError("n and p should be non-negative")  #抛出异常
