按记录比较元组值

Question

我有一个有序的元组(它的二维，列0是我的结尾，我想要比较它& column1有完整的urls)，在“列”我必须比较第一个值和第二个值，如果它们是相同的，将第一个值保存到其他列表并重复。我想将每一项都与下面的一项进行比较，无论它们是否相等。

元组：

[('https://www.topart-online.com/de/Rose%2C-Micle%2C-kupfer%2C-52cm%2C-Oe-9cm/c-KAT240/a-XH0124KP', '/a-XH0124KP'), ('https://www.topart-online.com/de/Rose%2C-Micle%2C-kupfer%2C-52cm%2C-Oe-9cm/c-KAT183/a-XH0124KP', '/a-XH0124KP'), ('https://www.topart-online.com/de/Rose%2C-Micle%2C-kupfer%2C-52cm%2C-Oe-9cm/c-KAT173/a-XH0124KP', '/a-XH0124KP'), ('https://www.topart-online.com/de/Liguster-Zweig-50cm-mit-Glitter/c-KAT184/a-XM0721', '/a-XM0721'), ('https://www.topart-online.com/de/3D-Stern-schwarz-mit-Glitter%2C-7%2C5-cm---SUPER-DEAL/c-KAT14/a-XM1633ZW', '/a-XM1633ZW'), ('https://www.topart-online.com/de/Christbaumschmuck%2C-Zweige%2C-gold-30-cm----SUPER-DEAL/c-KAT14/a-XP0091', '/a-XP0091')]

我想要比较提取的url的productnumber，因为每个产品都可能在多个url中找到。

我的排序尝试：

sized = len(complete_links2) - 1

for index, tuple in enumerate(complete_links2):
    index = k
    k = index + 1  
    if k < sized:
        while complete_links2[index][1] == complete_links2[k][1]:
            k += 1
        if complete_links2[index][1] == complete_links2[k][1]:
            k -= 1 
        not_rep_links.append(complete_links2[index])     

complete_links3 = [a_tuple[0] for a_tuple in not_rep_links]

我的问题是，有一些独特的链接，get也过滤掉了，因为我的逻辑不是很好。

我还尝试了set，解压了元组，但不知道如何继续

我还是有点困惑，但这是你想要的吗？

list_ = [

products = []
links = []

for item in list_:
    if item[1] not in products:
        products.append(item[1])
        links.append(item[0])

print(links)
