Question

我有一个url的以下api输出。我需要从这些'所有'区域'的特定值，但我无法获取它。你可以在这里建议我需要改变的地方。

dict =[ { "Fabric": "Madgth", "Zones": "rqu_kan23_34334_6666_56713", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:65:36:e4:20:ea" }, { "Fabric": "Madgth", "Zones": "rqu_kan23_C9AE9F10_6666_ytr9", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:69:36:e4:20:ea" }, { "Fabric": "Madgth", "Zones": "sdgh_5672_kan23_asd0", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:62:46:e0:70:bc" }, { "Fabric": "Madgth", "Zones": "fdsf_ytr2_kan23_dsd1", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:6a:46:e0:70:t5" }, { "Fabric": "Madgth", "Zones": "asdasd_5673_kan21_sdg0", "Members": "00:00:00:00:c9:ae:9f:14 40:00:01:63:47:60:04:b2" }, { "Fabric": "Madgth", "Zones": "FGF546_ytr3_kan21_SHQ1", "Members": "00:00:00:00:c9:ae:9f:14 40:00:01:6b:47:60:04:b2" }, { "Fabric": "sdfsdf", "Zones": "rqu_kan23_C9AE9F11_6666_5678", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:60:36:e4:20:ea" }, { "Fabric": "sdfsdf", "Zones": "rqu_kan23_C9AE9F11_6666_ytr12", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:6c:36:e4:20:ea" }, { "Fabric": "sdfsdf", "Zones": "FGF1166_5673_kan23_SHQ0", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:63:46:e0:70:bc" }, { "Fabric": "sdfsdf", "Zones": "FGF1166_ytr3_kan23_SHQ1", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:6b:46:e0:70:bc" }, { "Fabric": "sdfsdf", "Zones": "FGF546_5670_kan21_SHQ0", "Members": "00:00:00:00:c9:ae:9f:15 40:00:01:60:47:60:04:b2" }, { "Fabric": "sdfsdf", "Zones": "FGF546_ytr0_kan21_SHQ1", "Members": "00:00:00:00:c9:ae:9f:15 00:00:00:00:47:60:04:b2" } ]
print dict['Zones']

我似乎得到以下错误。

文件“test.py”，第3行，in print dict ['Zones'] TypeError：元组索引必须是整数，而不是str

Answer 1

这里只是列表，你必须这样做。

<!----- HTML ----->
<div class="form-radio">
  <div class="radio">
    <label>
      <input type="radio" name="radio" onclick="show();" checked/>
      <i class="helper"></i>
      I can come
    </label>
  </div>
  <div class="radio">
    <label>
      <input type="radio" name="radio" onclick="hide();"/>
      <i class="helper"></i>
      I cant come
    </label>
  </div>
</div>

<div class="form-group extra">
  <input type="text" required="required" />
  <label class="control-label" for="input">Dietary Requirements</label>
  <i class="bar"></i>
</div>

<div class="form-group extra">
  <input type="text" required="required" />
  <label class="control-label" for="input">What song would you like played?</label>
  <i class="bar"></i>
</div>

您的示例和错误消息不匹配。作为字典列表给出的示例和错误消息对应于元组。

要使用所有dict[0]['Zones']

"Zones"

请不要将zones = [i['Zones'] for i in dict if 'Zones' in i]用作变量名。

评论中的澄清，

dict

你提出的咒语在声明中有一些错误，这里是固定的错误：

dict =[ { "Fabric": "Madgth", "Zones": "rqu_kan23_34334_6666_56713", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:65:36:e4:20:ea" }, { "Fabric": "Madgth", "Zones": "rqu_kan23_C9AE9F10_6666_ytr9", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:69:36:e4:20:ea" }, { "Fabric": "Madgth", "Zones": "sdgh_5672_kan23_asd0", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:62:46:e0:70:bc" }, { "Fabric": "Madgth", "Zones": "fdsf_ytr2_kan23_dsd1", "Members": "00:00:00:00:c9:ae:9f:10 40:00:01:6a:46:e0:70:t5" }, { "Fabric": "Madgth", "Zones": "asdasd_5673_kan21_sdg0", "Members": "00:00:00:00:c9:ae:9f:14 40:00:01:63:47:60:04:b2" }, { "Fabric": "Madgth", "Zones": "FGF546_ytr3_kan21_SHQ1", "Members": "00:00:00:00:c9:ae:9f:14 40:00:01:6b:47:60:04:b2" }, { "Fabric": "sdfsdf", "zones": "rqu_kan23_C9AE9F11_6666_5678", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:60:36:e4:20:ea" }, { "Fabric": "sdfsdf", "Zones": "rqu_kan23_C9AE9F11_6666_ytr12", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:6c:36:e4:20:ea" }, { "Fabric": "sdfsdf", "Zones": "FGF1166_5673_kan23_SHQ0", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:63:46:e0:70:bc" }, { "Fabric": "sdfsdf", "Zones": "FGF1166_ytr3_kan23_SHQ1", "Members": "00:00:00:00:c9:ae:9f:11 40:00:01:6b:46:e0:70:bc" }, { "Fabric": "sdfsdf", "Zones": "FGF546_5670_kan21_SHQ0", "Members": "00:00:00:00:c9:ae:9f:15 40:00:01:60:47:60:04:b2" }, { "Fabric": "sdfsdf", "Zones": "FGF546_ytr0_kan21_SHQ1", "Members": "00:00:00:00:c9:ae:9f:15 00:00:00:00:47:60:04:b2" } ]

现在这样一个简单的代码就可以了：

list = []
for i in dict:
    list.append(i["Zones"])

Answer 3

您只需循环列表并打印即可。

for item in dict:
    print item['Zones']

不建议使用dict作为变量名称;）

从json输出中查找值
