这是一个使用 try-except-finally 结构的 Python 代码片段,它接受用户输入的两个值,将它们分别赋值给变量 a 和 b。然后,它试图计算 a 除以 b 的结果,并在除数为零的情况下捕获 ZeroDivisionError 异常,并输出一条错误消息。最后,无论是否出现异常,程序都会输出一条“程序结束”的消息。

a , b = eval ( input ()) try : print ( a / b ) except ①: print ("第二个参数不能为0!") finally : print ("程序结束")
The correct code is:
a, b = eval(input())
try:
print(a / b)
except ZeroDivisionError:
print("第二个参数不能为0!")
finally:
print("程序结束")
This code takes two values as input using the eval() function and stores them in variables a and b. Then, it tries to divide a by b inside a try block. If b is 0, it raises a ZeroDivisionError and executes the except block, which prints a message. Finally, it executes the finally block, which prints another message.
A, b = eval ( input ()) try : print ( a / b ) except ①: print ("第二个参数不能为0!") finally : print ("程序结束")
在 except 后面应该填写 ZeroDivisionError,因为这个错误是由于除数为0导致的。正确的代码应该是:
a, b = eval(input())
try:
print(a / b)
except ZeroDivisionError:
print("第二个参数不能为0!")
finally:
print("程序结束")
