如何檢索與具有價值的元組（蟒蛇）一定值

{'Stephen Curry': [(22.6, 5.1, 3.4)], 'Draymond Green': [(16.5, 10.3, 6.3)], 'Lebron James': [(29.7, 11.3, 8.9)]})

每個值對應於CATERGORY在這種情況下，格式爲（分，籃板，助攻），我試圖找回最大值關鍵每個玩家之間的點數，回扣和助攻數，並寫入文件。我無法獲得與正確密鑰對應的最大值。如何檢索與具有價值的元組（蟒蛇）一定值

乍一看，它可能是你打算在循環體中說「item」而不是「statAverages」？ –

你可以給我們這個代碼的輸出嗎？ – RoadRunner

你的字典有列表值，其中每個元組都包含一個元組，這是你的正確結構嗎？ –

我只想找到對應於這樣的最大值的關鍵是：

In [13]: max_pts_player = max(stats, key=lambda x:stats[x][0][0]) 

In [14]: max_pts_player 
Out[14]: 'Lebron James' 

In [15]: max_reb_player = max(stats, key=lambda x:stats[x][0][1]) 

In [16]: max_reb_player 
Out[16]: 'Lebron James' 

In [17]: max_assits_player = max(stats, key=lambda x:stats[x][0][2]) 

In [18]: max_assits_player 
Out[18]: 'Lebron James'

然後你可以檢索使用對應於統計玩家的名字和元組指數的最大靜：

In [19]: max_pts = stats[max_pts_player][0][0] 

In [20]: max_pts 
Out[20]: 29.7

但是，如果你想與統計開始了，

In [5]: max_pts 
Out[5]: 29.7 

In [6]: list(filter(lambda k:stats[k][0][0] == max_pts, stats))Out[6]: ['Lebron James']

這種方式可能會更好，如果不止一名玩家可以擁有最大數量。

好了，盡我的理解，這是我想出了：

d = {'Stephen Curry': [(23.6, 5.1, 3.4)], 'Draymond Green': [(16.5, 10.3, 6.3)], 'Lebron James': [(29.7, 11.3, 8.9)]} 

lst_tuples = sorted(d.items()) 

max_pts = max(lst_tuples, key = lambda x: x[1][0][0]) 
max_rebs = max(lst_tuples, key = lambda x: x[1][0][1]) 
max_assists = max(lst_tuples, key = lambda x: x[1][0][2]) 

print_stat_1 = "Max points player: {0}, with a score of {1}.\n" \ 
       .format(max_pts[0], max_pts[1][0][0]) 

print_stat_2 = "Max rebs player: {0}, with a score of {1}.\n" \ 
       .format(max_rebs[0], max_rebs[1][0][1]) 

print_stat_3 = "Max assists player: {0}, with a score of {1}.\n" \ 
       .format(max_assists[0], max_assists[1][0][2]) 

with open("best_player_stats.txt", "w") as text_file: 
    text_file.write("NBA Finals Stats\n") 
    text_file.write("----------------\n") 
    text_file.write("%s\n%s\n%s\n" % (print_stat_1, print_stat_2, print_stat_3)) 

with open("best_player_stats.txt","r") as file: 
    print(file.read())

打印出：

NBA Finals Stats 
---------------- 
Max points player: Lebron James, with a score of 29.7. 

Max rebs player: Lebron James, with a score of 11.3. 

Max assists player: Lebron James, with a score of 8.9.

如果我沒有做正確的事，請讓我知道在下面的評論。
