以下代码是用Python编写异常的正确方法吗?
class Calculator:
def power(self,n,p):
self.n=n
self.p=p
if self.n>=0 and self.p>=0:
return self.n**self.p
else:
return ("n and p should be non-negative")
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)
谢谢!
