如何使用复选框跳过Python中的日期

时间：2019-04-15 19:56:59

标签： python checkbox

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Box 1和2等于零，则输出正确
  • 如果方格1和2等于1，则输出正确
  • 如果Box 1等于1，而Box 2等于0，则输出是正确的
  • 如果Box 1等于0，Box 2等于1，则输出不正确，因为它跳过了week_one_refined返回值，比它应该执行的操作提前一周。

if BOX_2 == 1:
    week_one_refined = week_one_refined

答案实际上似乎复杂得多，但实际上却很简单。

按照流程图操作，使我了解了需要打开的复选框的所有可能组合。最终看起来像一个反向比赛。最后，它使用嵌套的for循环来使其起作用。

为循环中的某些不一致而致歉...就像重复值一样。我花了一段时间才找出正确的方法。
