如何将循环数据输出到嵌套列表中？

用户名

a = [
     [
      ['game1_teamA_player_1_a', 'game1_teamA_player_1_b', 'game1_teamA_player_1_c'],
      ['game1_teamB_player_2_a', 'game1_teamB_player_2_b', 'game1_teamB_player_2_c']
     ],

     [
      ['game2_teamA_player_1_a', 'game2_teamA_player_1_b', 'game2_teamA_player_1_c'],
      ['game2_teamB_player_2_a', 'game2_teamB_player_2_b', 'game2_teamB_player_2_c']
     ]
    ]

inj_main = []

for b in a: #  2 teams per game

    for c in b: #  3 stats per player, 2 players per team
        inja = c[0]
        injb = c[1]
        injc = c[2]
        inj_html = '<tr>' + inja + '</tr><tr>' + injb + '</tr><tr>' + injc + '</tr>'
        inj_main.append(inj_html)

print(inj_main)

我试图将数据放入列表中a并附加HTML<tr>标记，然后将其返回为与相同的列表格式a。a包括2场比赛，每场比赛有2支球队，每支球队有2个球员，每个球员都有3个统计数据。我的目标是召唤a[0]并让其返回嵌套有玩家信息的2支球队。现在打印时inj_main，它将返回同一列表中的所有内容。我不知道如何正确嵌套。

电流输出：

['<tr>game1_teamA_player_1_a</tr><tr>game1_teamA_player_1_b</tr<tr>game1_teamA_player_1_c</tr>', 

 '<tr>game1_teamB_player_2_a</tr><tr>game1_teamB_player_2_b</tr><tr>game1_teamB_player_2_c</tr>', 

 '<tr>game2_teamA_player_1_a</tr><tr>game2_teamA_player_1_b</tr><tr>game2_teamA_player_1_c</tr>', 

 '<tr>game2_teamB_player_2_a</tr><tr>game2_teamB_player_2_b</tr><tr>game2_teamB_player_2_c</tr>']

所需输出：

[
  ['<tr>game1_teamA_player_1_a</tr><tr>game1_teamA_player_1_b</tr><tr>game1_teamA_player_1_c</tr>', 

   '<tr>game1_teamB_player_2_a</tr><tr>game1_teamB_player_2_b</tr><tr>game1_teamB_player_2_c</tr>'
  ], 

  ['<tr>game2_teamA_player_1_a</tr><tr>game2_teamA_player_1_b</tr><tr>game2_teamA_player_1_c</tr>', 

   '<tr>game2_teamB_player_2_a</tr><tr>game2_teamB_player_2_b</tr><tr>game2_teamB_player_2_c</tr>'
  ]
]

为了获得结果，我必须对您的代码进行一些小的更改。

您需要从内部循环中捕获列表，并将其作为列表存储到主列表（inj_main）。为此，您需要创建一个临时列表并将其存储。

请参阅我的代码，并提供有关更改的注释。

a = [
     [
      ['game1_teamA_player_1_a', 'game1_teamA_player_1_b', 'game1_teamA_player_1_c'],
      ['game1_teamB_player_2_a', 'game1_teamB_player_2_b', 'game1_teamB_player_2_c']
     ],

     [
      ['game2_teamA_player_1_a', 'game2_teamA_player_1_b', 'game2_teamA_player_1_c'],
      ['game2_teamB_player_2_a', 'game2_teamB_player_2_b', 'game2_teamB_player_2_c']
     ]
    ]

inj_main = []

for b in a: #  2 teams per game
    inj_temp = [] #setup a temp list
    for c in b: #  3 stats per player, 2 players per team
        inja = c[0]
        injb = c[1]
        injc = c[2]
        inj_html = '<tr>' + inja + '</tr><tr>' + injb + '</tr><tr>' + injc + '</tr>'

        inj_temp.append(inj_html) #add to temp list

    inj_main.append(inj_temp) #add the temp list to main list

print(inj_main)

其输出将是：

[
  ['<tr>game1_teamA_player_1_a</tr><tr>game1_teamA_player_1_b</tr><tr>game1_teamA_player_1_c</tr>', 

   '<tr>game1_teamB_player_2_a</tr><tr>game1_teamB_player_2_b</tr><tr>game1_teamB_player_2_c</tr>'
  ], 

  ['<tr>game2_teamA_player_1_a</tr><tr>game2_teamA_player_1_b</tr><tr>game2_teamA_player_1_c</tr>', 

   '<tr>game2_teamB_player_2_a</tr><tr>game2_teamB_player_2_b</tr><tr>game2_teamB_player_2_c</tr>'
  ]

]
