在循环时，尝试except和其他有问题的函数

Question

我正在用python创建一个bingo/housie票据创建者。票有9行3列。这意味着9*3网格上有27个空间。垂直方向为9行，水平方向为3列。每行只能容纳3个随机数。第一行可以容纳1,9中的随机数。第二行可以容纳10,19之间的随机数。第三行可以容纳20,29之间的随机数。第四行可以容纳30,39之间的随机数。第五行可以容纳40,49之间的随机数。第六行可以容纳50,59之间的随机数。第七行可以容纳60,69之间的随机数。第八行可以容纳70,79之间的随机数。第九行可以容纳80,90之间的随机数。这是车票的参考图片 我计划用python创建一个随机票证。这是我为它创建的脚本。为了更好地理解，它有所有的评论

ticketGen()

我得到了一些混合输出： 代码给出的输出不正确：

[8] [14] [21, 25, 21] [32] [42, 47, 42] [55] [60, 66, 60] [76] [82]

正确的方式和代码给出的输出：

[7, 2] [16, 14] [28] [34] [40] [59, 56, 52] [68, 61, 64] [77] [83]

正如您所看到的，它的输出是混合的。第一个输出的问题是数字不能重复，并且一行不能超过3个数字。我无法找到这个bug是如何发生的，因为我为重复设置了一个try-except语句，为少于3个数字设置了一个if语句。如果您能发现任何问题并知道解决方法，请这样做。这对我来说意义重大。多谢各位

编辑-代码现在已经根据第一个答案进行了更改，但我得到了这些结果。还有一点很明显，它一行有3个以上的数字，它们是重复的数字。想不出办法请帮忙

Answer 1

在while循环中，更改以下内容-

while u < 6:
        randomNumGiver = random.randint(1,9)
        if randomNumGiver == 1 and numOfNums > 0 and row1.__len__() < 3:
            ranRow1NumGen()
        elif randomNumGiver == 2 and numOfNums > 0 and row2.__len__() < 3:
            ranRow2NumGen() ..........

至-

while u < 6:
    randomNumGiver = random.randint(1,9)
    if numOfNums > 0:
        if randomNumGiver == 1 and len(row1) < 3:
            ranRow1NumGen()
        elif randomNumGiver == 2 and len(row2) < 3:
            ranRow2NumGen()
        elif randomNumGiver == 3 and len(row3) < 3:
            ranRow3NumGen()
        elif randomNumGiver == 4 and len(row4) < 3:
            ranRow4NumGen()
        elif randomNumGiver == 5 and len(row5) < 3:
            ranRow5NumGen()
        elif randomNumGiver == 6 and len(row6) < 3:
            ranRow6NumGen()
        elif randomNumGiver == 7 and len(row7) < 3:
            ranRow7NumGen()
        elif randomNumGiver == 8 and len(row8) < 3:
            ranRow8NumGen()
        elif randomNumGiver == 9 and len(row9) < 3:
            ranRow9NumGen()
        else:
            pass
    u = u+1

将numOfNums行设为公共行，然后改用len()，因为最好不要使用.__len__()

结果：（没有重复，当我多次尝试任何错误结果时超过3次）
