Json table_data

[
  {
    "country": "country one",
    "city": "city one",
    "Start Time": "21th December 2019 09:00 AM",
    "End time": "22th December 2019 03:00 PM"
  },
  {
   "country": "country two",
    "city": "city two",
    "Start Time": "23th December 2019 09:00 AM",
    "End time": "23th December 2019 03:00 PM"
  },
  {
 "country": "country three",
    "city": "city three",
    "Start Time": "24th December 2019 09:00 AM",
    "End time": "24th December 2019 03:00 PM"
  } 
]

所以我想要做的是寻找一个国家，一旦我找到了你想打印相关数据的国家到目前为止我已经这样做了

for dt in table_data:# this is not correct i think
    if("country one" == dt):
        print()

我不知道如何在 python 中解决这个问题任何帮助将不胜感激

【问题讨论】：

我建议您阅读有关 Python 的教程。具体来说，您需要了解字典以及如何使用它们。
if dt['country'] == "country one":
@Code-Apprentice 这是 Python，不是 JS。
@Barmar 哎呀。谢谢你的收获。我想我看到了 JSON 标记并跳转到 JavaScript。

【解决方案1】：

我建议你从更简单的开始。假设您有一个country 对象：

country = {
    "country": "country one",
    "city": "city one",
    "Start Time": "21th December 2019 09:00 AM",
    "End time": "22th December 2019 03:00 PM"
  }

现在我们需要一个函数来打印这个对象：

def print_country(c):
    pass

第一步是弄清楚如何填写这个函数的细节。

【解决方案2】：

试试：

import json

data = json.loads("""
[
  {
    "country": "country one",
    "city": "city one",
    "Start Time": "21th December 2019 09:00 AM",
    "End time": "22th December 2019 03:00 PM"
  },
  {
   "country": "country two",
    "city": "city two",
    "Start Time": "23th December 2019 09:00 AM",
    "End time": "23th December 2019 03:00 PM"
  },
  {
 "country": "country three",
    "city": "city three",
    "Start Time": "24th December 2019 09:00 AM",
    "End time": "24th December 2019 03:00 PM"
  } 
]
""")

for this_country in data:
    if this_country['country'] == 'country two':
        print("\n".join([": ".join(k) for k in this_country.items()]))

输出：

country: country two
city: city two
Start Time: 23th December 2019 09:00 AM
End time: 23th December 2019 03:00 PM

类似的东西。

for data in table_data:
    if data['country'] == 'country one':
        print(data)
