我如何允许我的尝试块多次工作？

因此，我在上课时一直在尝试进行循环，但是我发现修复错误曾经有效。这是我的代码：

class team:
    def __init__(self,budget):
        self.budget = budget      

def test_func():
    team.budget = input("How much money should your baseball team own? ")
    try:
        team.budget = int(team.budget)
    except ValueError:
        print("Either you added a dollar sign, put in text or tried something weird. Either way, don't do that.")
        team.budget = input("How much money should your baseball team own? ")

test_func()

此尝试块应阻止任何不是整数的东西，但是这是我两次导致错误时发生的事情：

。用户进入可以接受的东西？

非常感谢！

So I've been trying to do a loop when working with classes but I find that fixing errors work once. Here's my code:

class team:
    def __init__(self,budget):
        self.budget = budget      

def test_func():
    team.budget = input("How much money should your baseball team own? ")
    try:
        team.budget = int(team.budget)
    except ValueError:
        print("Either you added a dollar sign, put in text or tried something weird. Either way, don't do that.")
        team.budget = input("How much money should your baseball team own? ")

test_func()

This try block should block anything that's not an integer, but here's what happens when I cause an error twice:

Is there something you'd recommend to allow the input to happen until the user enters in something acceptable?

Much thanks!

您需要使用循环重复提示，直到输入有效的整数为止。

def test_func():
    while True:
        team.budget = input("How much money should your baseball team own? ")
        try:
            team.budget = int(team.budget)

            break  # Stop the loop since the input is valid.
        except ValueError:
            print("Either you added a dollar sign, put in text or tried something weird. Either way, don't do that.")

You need to use a loop to repeat the prompt until a valid integer is entered.

def test_func():
    while True:
        team.budget = input("How much money should your baseball team own? ")
        try:
            team.budget = int(team.budget)

            break  # Stop the loop since the input is valid.
        except ValueError:
            print("Either you added a dollar sign, put in text or tried something weird. Either way, don't do that.")
