如何使用复选框跳过Python中的日期

我有4个复选框，每个复选框代表一个日期，例如：

Week 1: 01/01/2019  [  ] - checkbox 1
Week 2: 08/01/2019  [  ] - checkbox 2
Week 3: 15/01/2019  [  ] - checkbox 3
Week 4: 22/01/2019  [  ] - checkbox 4
Week To Pay 29/01/2019

我尝试了以下代码

W1 = W1 = timedelta(days=7)
week_one_raw = "01/01/2019"
week_one_raw = datetime.strptime(FIXED_WEEK_1, '%d/%m/%Y')
week_one_refined = week_one_raw
week_two_refined = week_one_raw + W1
week_three_refined = week_two_refined + W1
week_four_refined = week_three_refined + W1
week_to_pay_refined = week_four_refined + W1

if BOX_1 == 1:
    week_one_refined = week_one_raw + W1
    week_two_refined = week_one_refined + W1
    week_three_refined = week_two_refined + W1
    week_four_refined = week_three_refined + W1
    week_to_pay_refined = week_four_refined + W1

if BOX_1 == 0:
    week_one_refined = week_one_raw
    week_two_refined = week_one_raw + W1
    week_three_refined = week_two_refined + W1
    week_four_refined = week_three_refined + W1
    week_to_pay_refined = week_four_refined + W1

if BOX_2 == 1:
    week_one_refined = week_one_refined + W1
    week_two_refined = week_two_refined + W1
    week_three_refined = week_two_refined + W1
    week_four_refined = week_three_refined + W1
    week_to_pay_refined = week_four_refined + W1

if BOX_2 == 0:
    week_one_refined = week_one_refined
    week_two_refined = week_two_refined
    week_three_refined = week_three_refined
    week_four_refined = week_four_refined
    week_to_pay_refined = week_four_refined + W1

• 如果框1和框2等于零，则输出正确
• 如果框1和框2等于1，则输出正确
• 如果框1等于1，框2等于零，则输出正确
• 如果框1等于零，框2等于1，则输出不正确，因为它跳过了一周的时间，返回的时间比应该执行的时间提前了一周

答案实际上似乎要复杂得多，但在实践中却很简单

按照流程图，我浏览了所有可能需要打开的复选框组合。最终看起来像是一场逆转的比赛。最后，使用嵌套for循环使其运行

为循环中的一些不一致表示歉意…如重复值。我花了一段时间才想出正确的方法。

当框1和框2=0时，这个方法有效当框1=1和框2=1时，这个方法有效当框1和框2都=1时，这个方法有效，但当框1=0和框2=1时，这个方法无效。您可以在代码中显示如何设置框1和框2的值，如何打印输出，您现在的输出是什么？您期望的输出是什么？感谢您的帮助…这是一个让我抓狂的简单错误…它工作正常，除非您连续选中两个框…它不会跳过两周
