python - 如何让我的计数重置为循环

Question

这是我的代码:

for count in range(1,numGames+1):
    print()
    try:
        print("Game", str(count))
        atBats = input("How many at bats did the player have? ")
        atBats = int(atBats)
        hits = input("How many hits did the player have? ")
        hits = int(hits)
        battingAverage = (hits / atBats)
    except Exception as err:
        print("Please enter a number")
        print(err)

目前，当为游戏 1 的 hits 或 atBats 输入字母时，它会抛出异常并提示 Please enter a number,但它会直接进入游戏 2，而不会让用户有机会为游戏 1 输入新的内容。

我想知道是否有任何方法可以在抛出异常时重置游戏计数。

使用 while 循环在输入无效时运行并在有效时中断。

for count in range(1,numGames+1):
    print()
    while True:
        try:
            print("Game",str(count))
            atBats=input("How many at bats did the player have? ")
            atBats=int(atBats)
            hits=input("How many hits did the player have? ")
            hits=int(hits)
            battingAverage=hits/atBats
        except Exception as err:
            print("Please enter a number")
            print(err)
            continue
        break
