def handleData(self, data):
    players = self.gameData["participants"]
    teams = {}
    for player in players:
        if player["teamId"] == 100:
            teams["team A"] = player
        else:
            teams["team B"] = player

正在处理的数据是一个包含多个字典的列表。也许这个问题分开了？

这里是gameData中的内容[＆＃34;参与者＆＃34;]

我认为你想要的是每个球队都有一个球员名单，在这种情况下你可以这样做：

def handleData(self, data):
    players = self.gameData["participants"]
    teams = {}
    for player in players:
        if player["teamId"] == 100:
            teams.setdefault("team A", []).append(player)
        else:
            teams.setdefault("team B", []).append(player)

这样做会循环播放玩家，如果玩家应该在A队中，则将其附加到团队词典中team A键的玩家列表中。如果setdefault调用尚未存在，则<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:drawable="@drawable/vopressed" /> //light blue <item android:state_selected="true" android:drawable="@drawable/voselected" /> //blue <item android:drawable="@drawable/vo" /> //black </selector> 调用会创建该列表。

如果您的数据不是问题，请尝试以python生成器表达式的形式执行代码：

答案 2 :(得分：0)

这更像是评论，我没有权利这样做。你的循环似乎很好，你期待的结果是什么？您是否试图保留包含该团队中所有玩家的两个列表的字典？

在这种情况下，每次运行循环时都要为其分配一个新值，而不是附加到列表中。尝试类似：

players = [{'name':'Player A','teamID':100}, \
           {'name':'Player B','teamID':100}, \
           {'name':'Player C','teamID':200}, \
           {'name':'Player D','teamID':200}]

teams={'Team A':[],'Team B':[]}
for player in players:
    if player['teamID'] == 100:
        teams['Team A'].append(player['name'])
    else:
        teams['Team B'].append(player['name'])

for player in teams['Team A']:
    print(player)
print()
for player in teams['Team B']:
    print(player)

这会产生输出：

Player A
Player B

Player C
Player D
