python - 如何为每次迭代创建一个带有附加的独立列表？
问题描述
我通过 API 获得以下原始数据：

为了更好地阅读，我使用了 pprint 包，以结构化的方式显示数据（但是，上面的数据用于我的函数，因为它是一个列表，而 pprint 包将其说明为字典 - 所以这可能是一个有点误导）：

我的用例：
我想检索 response_id、用户的电子邮件和每个响应的所有答案。为此，我已经编写了以下函数（RESPS 变量包含上述所有数据）：
def structure_response (RESPS): # returns response ID, user e-mail and answers
answers = []
count = 1
for i in RESPS: # loops through list of responses containing dictionaries
for key, value in i.items():
if key == "response_id": # returns response_id
response_id = value
if key == "answers": # returns email
user_email = value[-1]["email"]
for j in value: # returns answers | value is a list containing dictionaries
for key, value in j.items():
if key == "text":
answers.append(value)
#Print Output
print("Response {} :".format(count))
print("Response ID: " + str(response_id))
print("User's E-Mail Adress: " + str(user_email))
print("Answers : " + str(answers))
print("\n")
count += 1
# Call Function
structure_response(RESPS)
输出：

我的问题：
现在，答案列表会附加在每个响应的每个迭代中。但是，我想在每次响应后停止附加。
我想要的输出：

谢谢您的帮助！
解决方案
如果dct问题中的字典是您的字典，您可以执行以下操作：
for i, d in enumerate(dct["items"], 1):
print("Response {}:".format(i))
print("Response ID: {}".format(d["response_id"]))
print(
"User's E-Mail Adress: {}".format(
next(v for v in d["answers"] if v["type"] == "email")["email"]
)
)
print("Answers: ", [v["text"] for v in d["answers"] if v["type"] == "text"])
print()

编辑：如果你有一个列表lst：
for i, d in enumerate(lst, 1):
print("Response {}:".format(i))
print("Response ID: {}".format(d["response_id"]))
print(
"User's E-Mail Adress: {}".format(
next(v for v in d["answers"] if v["type"] == "email")["email"]
)
)
print("Answers: ", [v["text"] for v in d["answers"] if v["type"] == "text"])
print()
