如何根据名称从列表中获取重复项

Question

我正在从服务器访问一些文件并打印结果，但是如何根据打印结果中的名称获取重复项。

from datetime import datetime
class EsriApiMaps:

    def __init__(self, portal, item_type, query):
        self.item_type = item_type
        self.query_ = query
        self.portal = portal

    def query_maps(self):
        api_query_result = self.portal.content.search(query=self.query_, item_type=self.item_type)
        l = [] # we will store all the services e,g url,id,owner etc


        for l in api_query_result:
            l_created_time = datetime.fromtimestamp(round(l.created / 1000))
            l_modified_time = datetime.fromtimestamp(round(l.modified / 1000))
            df = ("Name: " + l.title + "ID: " + l.id + ", Owner: " + l.owner + ", Created: " + str(l_created_time) + ", Modified: " + str(l_modified_time))
            print(df)

我试过这个得到以下结果，

我试过使用，

names = df.Name.value_counts()
names[names>1]

但我收到此错误 AttributeError: 'str' object has no attribute 'Name'

如何根据名称获取重复项？

预期结果是

df 它是一个字符串，而不是数据框，您应该使用 API 查询的结果创建一个数据框，然后您可以使用数据框方法。

您可以用结果创建一个列表，然后用它初始化数据框。

def query_maps(self):
        api_query_result = self.portal.content.search(query=self.query_, item_type=self.item_type)
        data = []

        for l in api_query_result:
            l_created_time = datetime.fromtimestamp(round(l.created / 1000))
            l_modified_time = datetime.fromtimestamp(round(l.modified / 1000))
            data.append({"Name": l.title, "ID": l.id, "Owner": l.owner, "Created": str(l_created_time), "Modified": str(l_modified_time)})
        df = pd.Dataframe(data)
