循环问题

Question

我有一个已经可以正常工作的函数，看起来像这样：

tolerance=5
def pmm_rag(data):

    if  ((data.SHIPMENT_MOT_x == 'AIR') & (data.latedeliverydate < data.m6plan)):
        return 'R'

    elif ((data.SHIPMENT_MOT_x == 'AIR') & (data.m6_event >= data.m6plan)):
        return 'G'

    elif ((data.SHIPMENT_MOT_x == 'AIR') & (data.m6_event >= data.m6plan)):
        return 'A'

    else:
        return ''

我想在函数2中添加条件，但未填充结果：

def pmm_rag(data):

    while data.m2 == '' is False:

        if  ((data.SHIPMENT_MOT_x == 'AIR') & (data.m6_event < data.m6plan)):
            return 'R'

        elif ((data.SHIPMENT_MOT_x == 'AIR') & (data.m6_event >= data.m6plan)):
            return 'G'

        elif ((data.SHIPMENT_MOT_x == 'AIR') & (data.m6_event >= data.m6plan)):
            return 'A'


    while data.m2 == '' is False:

        if  ((data.SHIPMENT_MOT_x == 'AIR') & (data.latedeliverydate < data.m6plan)):
            return 'R'

        elif ((data.SHIPMENT_MOT_x == 'AIR') & (data.latedeliverydate >= data.m6plan)):
            return 'G'

        elif ((data.SHIPMENT_MOT_x == 'AIR') & (data.latedeliverydate >= data.m6plan)):
             return 'A'

    else:
        return ''

实际上，我想引入一会儿来循环一下有m2和没有 public class Release { public int Id { get; set; } public string Name { get; set; } public DateTime StartDate { get; set; } public DateTime EndDate { get; set; } public string OwnerId { get; set; } public string OwnerName { get; set; } public bool Finished { get; set; } public bool InProgress { get; set; } public bool Aborted { get; set; } } 的行吗？ 我该怎么办？

您应该使用此条件。

if data.m2 != '':

如果要遍历data.m2的元素，则应使用“ for”语句：

for x in data.m2:
