[英]How to compare an objects in a list to another object that is in the same list?
nrmcdate是按名稱、class 和日期順序排列的列表。 此列表代表學生未參加的 class 和學生未參加的日期。 例如(john, 5537, datetime.datetime(2021, 5, 15, 0, 0))表示 john 在 2021 年 5 月 15 日沒有參加 class 5537
registered_lists是已注冊到該 class 的學生列表。 所以在這個列表中會有重復的名字。 例如。 ('JOHN', 5537), ('JOHN', 5620)表示 john 已注冊到 class 5620 和 5537。

目前，我需要將 nrmcdate 的日期與自身進行比較，看看日期是否相隔 3 天。 例如。（不是來自上面的列表） [(Aang, 12, datetime.datetime(2021, 05, 15)),( Ben, 22, datetime.datetime(2021, 05, 12)]因為列表中的對象是相隔三天，它將獲取名稱並與 registerd_lists 進行比較。一旦兩個名稱在注冊列表中匹配，程序將檢查 Aang 和 Ben 是否有共同的 class。output 例如。 (Aang, Ben, 16)這意味着 Aang 和 Ben 在同一個 class 16 中。
我一直在試圖弄清楚如何比較過去幾周的日期，我希望這里有人可以提供解決方案。
我將首先列出所有對
itertools.combinations(nrmcdate, 2) # don't forget to import
然后對於所有對
def common_class(pair, registered):
person1 = pair[0]
person2 = pair[1]
if (abs((person1[2] - person2[2]).days) >= 3): #check if 3 days apart
if common_classes := set(registered[person1[0]]).intersection(registered[person2[0]]): # they have a common class
return (person1[0], person2[0], common_classes)
return None
最后使用以下方法將registered_list列表轉換為字典：
result_dict = {}
for x in registered_list:
result_dict.setdefault(x[0], []).append(x[1])
然后把這一切放在一起：
import datetime
import itertools
nrmcdate = [("Aang", 12, datetime.datetime(2021, 5, 15)),( "Ben", 22, datetime.datetime(2021, 5, 12))]
registered_list = [('Ben', 5537), ('Aang', 5537)]
itertools.combinations(nrmcdate, 2)
def common_class(pair, registered):
person1 = pair[0]
person2 = pair[1]
if (abs((person1[2] - person2[2]).days) >= 3): #check if 3 days apart
if common_classes := set(registered[person1[0]]).intersection(registered[person2[0]]): # they have a common class
return (person1[0], person2[0], common_classes)
return None
result_dict = {}
for x in registered_list:
result_dict.setdefault(x[0], []).append(x[1])
print([res for x in itertools.combinations(nrmcdate, 2) if (res := common_class(x, result_dict))])
我希望這有效，它沒有經過真正的測試。
