Question

我正在尝试从嵌套字典中收集信息（从json加载）。我试图用for循环来做到这一点。我无法在字典中找到一个名为“players”的字典。 “玩家”包含带有玩家姓名及其ID的字典。我想提取那本字典。您可以在下面找到我的代码和数据样本。

我能够通过第一级迭代到字典，但我无法过滤掉更深层次。

我一直在寻找其他类似的问题，但他们正在解决字典迭代的不同问题。我无法将它们用于我的目的。我正在考虑使用data.keys（）[“players”]来提取我需要的信息，但我现在无法解决这个问题。

for key, value in dct.iteritems():
    if value == "players":
        for key, value in dct.iteritems():
            print key, value

我的数据样本：

{
"[CA1]": {
    "team_tag": "[CA1]",
    "team_name": "CzechAir",
    "team_captain": "MatejCzE",
    "players": {
        "PeatCZ": "",
        "MartyJameson": "",
        "MidnightMaximus": "",
        "vlak_in": "",
        "DareD3v1l": "",
        "Hugozhor78": ""
    }
},
"[GWDYC]": {
    "team_tag": "[GWDYC]",
    "team_name": "Guys Who Dated Your Cousin",
    "team_captain": "Teky1792",
    "players": {
        "wondy22": "",
        "dzavo1221": "",
        "Oremuss": "",
        "Straker741": "",
        "Vasek9266": ""
    }
}
}

Answer 1

外部循环中的每个value本身都是一个字典：

for key, value in dct.iteritems():
    if 'players' in value:
        for name, player in value['players'].iteritems():
            print name, player

在这里，首先测试嵌套字典中是否存在players键，如果是，则迭代players值的所有键和值，再次是字典。< / p>

Answer 2

for team in myData:
    for player,id in myData[team]['players'].iteritems():
        print "player %s has ID '%s'" %(player, id)
