循環只運行一次python

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

正在處理的數據是一個包含其中幾個字典的列表。也許這是問題的一部分？循環只運行一次python

這裏是什麼在GAMEDATA [「paticipants」]

大衛，給我們的數據，請。 'self.gameData [「參與者」]看起來像什麼？ –

更多代碼請 – MichaelMMeskhi

'data'參數根本沒有被使用。我假設你的意思是'self.gameData [「參與者」]'是一個字典列表。在這種情況下，這段代碼應該可以正常工作。另外，你只需要在字典中給玩家分配2個鍵。這意味着如果超過2個玩家，你只需要一個帶有2個密鑰的字典，每個密鑰都會有你的列表中最後一個匹配該密鑰條件的玩家。 – bigblind

我想你想要的是每隊擁有的球員名單，在這種情況下，你可以這樣做：

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)

這樣做是通過玩家循環，如果玩家應該在A隊，將其附加到球隊字典中的team A鍵中的球員列表。如果該列表尚不存在，則setdefault調用將創建該列表。

如果它不是你的數據的問題，嘗試在Python發電機的表現形式做你的代碼：

這更像是一個評論，我沒有特權那樣做呢。你的循環似乎很好，你期待的結果是什麼？你是否試圖保留包含該隊所有球員的兩份名單的字典？

在這種情況下，您每次運行循環而不是附加到列表時，都會爲其分配一個新值。嘗試是這樣的：

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)

這將產生輸出：

Player A 
Player B 

Player C 
Player D
