你也可以在 except 后面省略异常类型，这表示与任意异常相匹配（包括系统异常等）：node2:/root/python3#cat t9.py
try:s = input('please enter two numbers separated by comma: ')num1 = int(s.split(',')[0].strip())num2 = int(s.split(',')[1].strip())print(num1,num2)print(type(num1))print(type(num2))
except :print('aaaaaaaaaaa')node2:/root/python3#python3 t9.py
please enter two numbers separated by comma: a,b
aaaaaaaaaaa
