python：从for循环之外的多个for循环获取输出

Question

我有一个嵌套for循环，如下所示：

cv_list_dic = cv_list()
for cv in cv_list_dic['results']:
    cv_name = cv['name']
    if qq_cv(cv_name):
            cv_versions = (cv['versions'])
            cv_id_list = []
            for cv_ids in cv_versions:
                    ver_id = (cv_ids['id'])
                    cv_id_list.append(ver_id)
            max_id = (max(cv_id_list))
            qq_cv_id = (cv_name, max_id)
            print(qq_cv_id)

输出是一个元组列表（还有更多元组，这只是一个示例）：

('cv1', 152)
('cv2', 35)

我的问题是我需要那些for循环之外的元组。 我试图创建一个空列表并附加到它，但它只附加最后一项。你知道吗

Answer 1

这应该是可行的，将cv_list_dic定义为一个空列表（在循环开始之前），并将每次迭代的结果附加到这个列表中。你知道吗

cv_list_dic = cv_list()
qq_cv_id = []
for cv in cv_list_dic['results']:
    cv_name = cv['name']
    if qq_cv(cv_name):
            cv_versions = (cv['versions'])
            cv_id_list = []
            for cv_ids in cv_versions:
                    ver_id = (cv_ids['id'])
                    cv_id_list.append(ver_id)
            max_id = (max(cv_id_list))
            qq_cv_id.append((cv_name, max_id))
            print(qq_cv_id)

Answer 2

I have tried to create an empty list and append to it

这是正确的方向，所以您只需实际编写代码：）

cv_list_dic = cv_list()
results = [] # here is your list with results
for cv in cv_list_dic['results']:
    cv_name = cv['name']
    if qq_cv(cv_name):
            cv_versions = (cv['versions'])
            cv_id_list = []
            for cv_ids in cv_versions:
                    ver_id = (cv_ids['id'])
                    cv_id_list.append(ver_id)
            max_id = (max(cv_id_list))
            qq_cv_id = (cv_name, max_id)
            print(qq_cv_id)
            results.append(print(qq_cv_id))
