如何过滤一组字典，以便我可以根据*另一个*键是否满足特定条件从一个键中提取值？
How do I filter a group of dictionaries so that I can extract values from one key based on whether *another* key meets certain conditions?
这里是业余到中级 Python 程序员。
我有一个 Excel .csv，我正试图从中提取一些特定数据。我已经设法将原始数据提取到 Python 中的字典列表中。数据由大约十几个不同的键组成（Excel sheet中的列），但我需要的只是两个键中的数据。
我想根据second键中对应的值是否满足一定条件，提取其中一个键的值。两个key分别是“UnitId”和“A5000 Overall satisfaction”（这是客服相关的数据），我想提取每一个对应A5000值为5的UnitId值。
问题到现在为止，我尝试执行此操作的 none 个函数设法提取 任何东西 ，并且总是产生一个空字典或列表（取决于我尝试的方法）。我最近的函数尝试给了我 一些 进步，但结果并不包含我想要的所有数据。
我试图简单地提取每本 A5000 值为 5 的字典，希望一旦我将列表缩小到我需要的字典，就可以从那里提取 UnitId。但是，它没有给我所有 A5000 值为 5 的字典，而是给了我 A5000 值为 5 的 单个 字典结果的所有键。
这是我最近尝试的代码:
import csv
compiled_data = []
all_5_ratings = dict()
with open("C:\%%%%%%%%%%%\CW test file.csv") as CW_test_file:
#Here is the code I used to display the raw data in the console
CWtest_dict = csv.DictReader(CW_test_file)
for row in CWtest_dict:
compiled_data.append(row)
print(compiled_data)
print("################################################")
#Here is my most recent attempted function to extract the desired data:
for dict in compiled_data:
for key, value in dict.items():
if key == "A5000 Overall satisfaction" and value == "5":
all_5_ratings.update(dict)
else:
pass
print(all_5_ratings)
#Below is a failed previous attempt
all_fives = [x for x in compiled_data if x["A5000 Overall satisfaction"] >= "5"]
print(all_fives)
这里有一个pastebin link到compiled_data的样例供参考（这里直接post太长了，而且完整的东西对于免费的pastebin用户来说太大了）：
这里是我用现有代码得到的结果：
{
"VisitDate": "10/28/2021 21:58",
"UnitId": "2",
"A4000 Type of visit": "2",
"A5000 Overall satisfaction": "5",
"A6000 Likelihood to return": "5",
"A7000 Likelihood to recommend": "5",
"A8000 Value for Price": "5",
"A9000 Friendliness of host/hostess": "5",
"A10000 Wait time to be seated": "5",
"A11000 Friendliness of server": "4",
"A12000 Wait time for drinks": "5",
"A13000 Wait time for food": "5",
"A14000 Server's menu knowledge": "5"
}
最后，我的问题是：如何提取所有个对应A5000值为5的UnitId值？
你的问题是你在需要列表的地方使用了字典。 all_5_ratings.update(dict) 正在覆盖您之前的任何条目。您可以使用列表，然后使用 'append' 而不是像您第一次读取数据时那样使用 'update'。
我不确定我是否明白你想做什么。但此脚本将 A5000 为 5 的所有评论放入结果数组中：

result = []
for row in data:
if row['A5000 Overall satisfaction'] == '5':

这里是单行的：
result = [row['UnitId'] for row in data if row['A5000 Overall satisfaction'] == '5']
这里是业余到中级 Python 程序员。
我有一个 Excel .csv，我正试图从中提取一些特定数据。我已经设法将原始数据提取到 Python 中的字典列表中。数据由大约十几个不同的键组成（Excel sheet中的列），但我需要的只是两个键中的数据。
我想根据second键中对应的值是否满足一定条件，提取其中一个键的值。两个key分别是“UnitId”和“A5000 Overall satisfaction”（这是客服相关的数据），我想提取每一个对应A5000值为5的UnitId值。
问题到现在为止，我尝试执行此操作的 none 个函数设法提取 任何东西 ，并且总是产生一个空字典或列表（取决于我尝试的方法）。我最近的函数尝试给了我 一些 进步，但结果并不包含我想要的所有数据。
我试图简单地提取每本 A5000 值为 5 的字典，希望一旦我将列表缩小到我需要的字典，就可以从那里提取 UnitId。但是，它没有给我所有 A5000 值为 5 的字典，而是给了我 A5000 值为 5 的 单个 字典结果的所有键。
这是我最近尝试的代码:
import csv
compiled_data = []
all_5_ratings = dict()
with open("C:\%%%%%%%%%%%\CW test file.csv") as CW_test_file:
#Here is the code I used to display the raw data in the console
CWtest_dict = csv.DictReader(CW_test_file)
for row in CWtest_dict:
compiled_data.append(row)
print(compiled_data)
print("################################################")
#Here is my most recent attempted function to extract the desired data:
for dict in compiled_data:
for key, value in dict.items():
if key == "A5000 Overall satisfaction" and value == "5":
all_5_ratings.update(dict)
else:
pass
print(all_5_ratings)
#Below is a failed previous attempt
all_fives = [x for x in compiled_data if x["A5000 Overall satisfaction"] >= "5"]
print(all_fives)
这里有一个pastebin link到compiled_data的样例供参考（这里直接post太长了，而且完整的东西对于免费的pastebin用户来说太大了）：
这里是我用现有代码得到的结果：
{
"VisitDate": "10/28/2021 21:58",
"UnitId": "2",
"A4000 Type of visit": "2",
"A5000 Overall satisfaction": "5",
"A6000 Likelihood to return": "5",
"A7000 Likelihood to recommend": "5",
"A8000 Value for Price": "5",
"A9000 Friendliness of host/hostess": "5",
"A10000 Wait time to be seated": "5",
"A11000 Friendliness of server": "4",
"A12000 Wait time for drinks": "5",
"A13000 Wait time for food": "5",
"A14000 Server's menu knowledge": "5"
}
最后，我的问题是：如何提取所有个对应A5000值为5的UnitId值？
你的问题是你在需要列表的地方使用了字典。 all_5_ratings.update(dict) 正在覆盖您之前的任何条目。您可以使用列表，然后使用 'append' 而不是像您第一次读取数据时那样使用 'update'。
我不确定我是否明白你想做什么。但此脚本将 A5000 为 5 的所有评论放入结果数组中：
