如何使此循环继续前进，直到输入正确的输入？

Question

这是我编写的代码，我现在正在学习python，但是告诉我如何使这个循环继续前进，直到我们达到x和y的正确条件是整数和y＆gt; 0，这样它就不会抛出异常。

def problem_2():
    while True:
        try:
            x = int(input("Enter the value of X"))
            y = int(input("Enter the value of Y"))
            print(x/y)
        except ZeroDivisionError:
            print("You have divided the number by zero")
        except TypeError:
            print("Please Enter Integer in both the cases")

problem_2()

Answer 1

您可以简单地做一个无限的时，循环以X和Y为输入并检查您的状况。

1. 如果满足您的病情，请进行您想做的处理并打破循环。
2. 如果您没有满足条件，请再次继续循环，同一件事将重复直到满足条件。

while true:
    #take your input
    #check your condition 
    #if condition not met 
        continue
    #if condition met
        #do your stuff
        break

Answer 2

检查y＆gt; 0在您的例外捕获块之后：

def problem_2():
    while True:
        try:
            x = int(input("Enter the value of X"))
            y = int(input("Enter the value of Y"))
            print(x/y)
        except ZeroDivisionError:
            print("You have divided the number by zero")
        except TypeError:
            print("Please Enter Integer in both the cases")
        # No exception was raised, check y
        if y > 0:
            break

problem_2()

另外，为了避免使用异常处理，您可以这样做：

def problem_2():
    while True:
        x = input("Enter the value of X")
        y = input("Enter the value of Y")
        if not x.isdigit() or not y.isdigit():
            print("Please enter Integer in both the cases")
            continue
        x, y = int(x), int(y)
        if x == 0 or y == 0:
            print("Cannot divide by zero")
            continue
        # If we reached here, the input is valid
        print(x/y)
        break

problem_2()

Answer 3

尝试这个我希望它能适合您想要的东西。谢谢

def problem_2():
    while True:
        x = input("Enter the value of x: ")
        y = input("Enter the value of y: ")
        if x.isdigit() and y.isdigit():
            if int(y)>0:
                print(int(x)/int(y))
            else:
                pass 
        else:
            continue
problem_2()
