过滤掉字典列表是否具有集合中的键
python 264
原文标题 :Filtering out if the dictionary list has the key in a set
events=[
{'creator': {'email': 'a@hotmail.com', 'self': True}, 'organizer': {'email': 'a@hotmail.com', 'self': True}, 'start': {'dateTime': '2022-03-15T07:00:00-0700', 'timeZone': 'America/Vancouver'}, 'end': {'dateTime': '2022-03-15T07:30:00-0700', 'timeZone': 'America/Vancouver'}, 'attendees': [{'email': 'b@hotmail.com', 'responseStatus': 'needsAction'}, {'email': 'a@hotmail.com', 'organizer': True, 'self': True, 'responseStatus': 'needsAction'}]},
{'creator': {'email': 'a@hotmail.com', 'self': True}, 'organizer': {'email': 'a@hotmail.com', 'self': True}, 'start': {'dateTime': '2022-03-15T07:30:00-0700', 'timeZone': 'America/Vancouver'}, 'end': {'dateTime': '2022-03-15T08:00:00-0700', 'timeZone': 'America/Vancouver'}, 'attendees': [{'email': 'b@hotmail.com', 'responseStatus': 'needsAction'}, {'email': 'a@hotmail.com', 'organizer': True, 'self': True, 'responseStatus': 'needsAction'}]},
{'creator': {'email': 'a@hotmail.com', 'self': True}, 'organizer': {'email': 'a@hotmail.com', 'self': True}, 'start': {'dateTime': '2022-03-17T00:00:00-0700', 'timeZone': 'America/Vancouver'}, 'end': {'dateTime': '2022-03-17T00:30:00-0700', 'timeZone': 'America/Vancouver'}}

我想过滤一个字典列表(列表结构略有不同),如果它有一个有效的(在电子邮件中)不是组织者的 [‘attendee’][’email’]。所以 [‘attendees’][‘organizer’] 不能是使用的那个。
emails=['b@hotmail.com']
for e in events:
if e['attendees']['email'] in emails:
print(e)
生产
TypeError at /
list indices must be integers or slices, not str
应该输出:
{'kind': 'calendar#event', 'etag': '"1"', 'id': '1', 'status': 'confirmed', 'htmlLink': 'https://www.google.com/calendar/event?eid=1', 'created': '2022-03-14T00:08:11.000Z', 'updated': '2022-03-14T00:08:12.162Z', 'summary': 'Appointment', 'description': 'Online appointment', 'location': 'Online', 'creator': {'email': 'a@hotmail.com', 'self': True}, 'organizer': {'email': 'a@hotmail.com', 'self': True}, 'start': {'dateTime': '2022-03-15T07:00:00-0700', 'timeZone': 'America/Vancouver'}, 'end': {'dateTime': '2022-03-15T07:30:00-0700', 'timeZone': 'America/Vancouver'}, 'iCalUID': '1@google.com', 'sequence': 0, 'attendees': [{'email': 'b@hotmail.com', 'responseStatus': 'needsAction'}, {'email': 'a@hotmail.com', 'organizer': True, 'self': True, 'responseStatus': 'needsAction'}], 'reminders': {'useDefault': False, 'overrides': [{'method': 'email', 'minutes': 1440}, {'method': 'popup', 'minutes': 10}]}, 'eventType': 'default'},

该回答已被采纳!
e[‘attendees’] 是一个列表,因此您需要指定它的索引
for e in events: try: if e['attendees'][0]['email'] in emails: print(e) except KeyError: pass

您的第三个条目不包含“参加者”字段。因此,您的第三行代码将失败。
如果我对您的理解正确,您只想打印包含参加者的活动,该参加者的电子邮件包含在“电子邮件”列表中。如果这是真的,此代码将适用于您(假设没有与会者是合法的情况):
for e in events: isValid = True if e.__contains__("attendees"): for a in e["attendees"]: if a["email"] in emails: print(e)
