Question

我正在尝试学习 while 语句在 Python 中的工作原理。我正在尝试创建一个代码，该代码继续将 num1 和 num2 相乘，直到舍入 <= 10 或直到 num1 > num2。如果 10 轮前 num1 大于 num2，则循环结束，num1 获胜，否则获胜者为 num2。

我的输出只完整打印第一轮，然后一遍又一遍地打印 'Round = #'。我希望输出看起来像这样：

Initiate Math Competition:
Round = 1
1 = #
1 = #
2 = #
2 = #
2 = #
Round = 2
1 = #
1 = #
2 = #
2 = #
2 = #
...
Math Competition Closed
Winner = 1

注意：我无法更改主程序。另外，我理解这段代码的一个问题是，在继续阻止代码检查 num1 是否超过 num2 之前，内部循环已经完成，但我不知道如何修复它。

def math_competition(num1, multiply1, max_repitition_1, num2, multiply2, max_repitition_2):
    """
    -------------------------------------------------------
    Returns Winner of Math Competition.
    Use: winner = math_competition(num1, multiply1, max_repitition_1, num2, multiply2, max_repitition_2)
    -------------------------------------------------------
    Parameters:
        num1:  first value (int)
        multiply1: first multiplying factor (int)
        max_repitition_1: max repetition for the first value (int)
        num2: second value (int)
        multiply2: second multiplying factor (int)
        max_repitition_2: second repetition factor (int)
    Returns:
        winner - Winner of Math Competition 
    -------------------------------------------------------

    print('Initiate Math Competition:')
    rounds = 1
    first_counter = 0
    second_counter = 0
    winner = ''
    while rounds <= 10 and num1 < num2: 
        print('Round = {}'.format(rounds))
        while first_counter != max_repitition_1:
            num1 = num1 * multiply1
            print('1 = {}'.format(num1))
            first_counter += 1
        while second_counter != max_repitition_2:
            num2 = num2 * multiply2
            print('2 = {}'.format(num2))
            second_counter += 1
        if num1 > num2:
            winner = '1'
            break
        elif rounds <= 10 and num2 > num1:
            rounds += 1
            continue
        else:
            winner = '2'
    print('Math Competition Closed')
    return winner

for c in cases:
    winner = math_competition(c[0],c[1],c[2],c[3],c[4],c[5])

Python：如何让 while 循环在另一个 while 语句中继续？
