'dict' object has no attribute 'append' Json
提问by KekMeister Johhny
I have this code that adds 50 points to a user in my json file but I keep getting a 'dict' object has no attribute 'append'when trying to append new users to the users:
我有这段代码为我的 json 文件中的用户添加了 50 个点，但是'dict' object has no attribute 'append'在尝试将新用户附加到用户时我不断收到：
def updateUsers(chan):
j = urllib2.urlopen('http://tmi.twitch.tv/group/user/' + chan + '/chatters')
j_obj = json.load(j)
with open('dat.dat', 'r') as data_file:
data = json.load(data_file)
for dat in data['users']:
if dat in j_obj['chatters']['moderators'] or j_obj['chatters']['viewers']:
data['users']['tryhard_cupcake']['Points'] += 50
else:
data['users'].append([dat]) # append doesn't work here
with open('dat.dat', 'w') as out_file:
json.dump(data, out_file)
What is the proper way of adding new objects/users to users?
将新对象/用户添加到 的正确方法是users什么？

data['users'] = [dat]
If you want to append to the existing list.
如果要附加到现有列表。
templist = data['users']
templist.extend(dat)
data['users'] = templist

It seems that data['users']is a dictionary, so you can only use dictionary methods to add keys and values.
好像data['users']是字典，所以只能用字典的方法来添加键和值。
