Question

我真的不知道这里发生了什么 - 让我概述一下代码。

我从SFG WorldCup API中提取数据。

今天早些时候API的示例输出：

[
    {
        "match_number": 26,
        "location": "Arena da Baixada",
        "datetime": "2014-06-20T19:00:00.000-03:00",
        "status": "in progress",
        "home_team": {
            "country": "Honduras",
            "code": "HON",
            "goals": 1
        },
        "away_team": {
            "country": "Ecuador",
            "code": "ECU",
            "goals": 2
        },
        "winner": null,
        "home_team_events": [
            {
                "id": 290,
                "type_of_event": "yellow-card",
                "player": "Bernardez",
                "time": "7"
            },
            {
                "id": 291,

                "player": "Costly",
                "time": "31"
            },
            {
                "id": 294,
                "type_of_event": "substitution-in halftime",
                "player": "J.C. Garcia",
                "time": "46"
            },
            {
                "id": 297,
                "type_of_event": "substitution-in",
                "player": "M. Martinez",
                "time": "71"
            },
            {
                "id": 301,
                "type_of_event": "substitution-in",
                "player": "M. Chavez",
                "time": "83"
            },
            {
                "id": 293,
                "type_of_event": "yellow-card",
                "player": "Bengtson",
                "time": "453"
            }
        ],
        "away_team_events": [
            {
                "id": 292,
                "type_of_event": "goal",
                "player": "E. Valencia",
                "time": "34"
            },
            {
                "id": 295,
                "type_of_event": "yellow-card",
                "player": "A. Valencia",
                "time": "57"
            },
            {
                "id": 296,
                "type_of_event": "goal",
                "player": "E. Valencia",
                "time": "65"
            },
            {
                "id": 298,
                "type_of_event": "yellow-card",
                "player": "E. Valencia",
                "time": "73"
            },
            {
                "id": 299,
                "type_of_event": "yellow-card",
                "player": "Montero",
                "time": "80"
            },
            {
                "id": 300,
                "type_of_event": "substitution-in",
                "player": "Mendez",
                "time": "82"
            },
            {
                "id": 302,
                "type_of_event": "substitution-in",
                "player": "Gruezo",
                "time": "83"
            }
        ]
    }
]

有了这些数据，我的问题是在for循环中获取数据是有效的，但是在下面的while循环中却没有。

resp是来自api的回应...

     for jogo in resp.json():
         score = jogo['home_team']['goals']
     jogo = resp.json()
     while True:
         newscore = int(jogo['home_team']['goals'])

实际代码略有不同（while循环中的jogo['home_team']['goals']位于if语句中，但这是它的基本框架。

我得到的错误是while中的错误，它显示TypeError: list indices must be integers, not str

我不确定我是否将它与整数进行比较（我将其包含在int()中）。

造成这种情况的原因是什么，为什么不在第一次调用它。

谢谢！

PS让我知道这是否有任何意义=）

发布新代码更有意义：

 # here, jogo takes the value of each dict{} within the outer list[]
 for jogo in resp.json():
     score = jogo['home_team']['goals']

 # while here it is the outer list itself 
 jogo = resp.json()
 while True:
     newscore = int(jogo['home_team']['goals'])

如果你知道列表中只有一个结果，你可以使用

 jogo = resp.json()[0]

错误告诉你jogo需要一个整数索引（暗示它是一个列表类型或类似的），但是你传递一个字符串索引（显示你预期它是一个字典）。这是导致错误的声明：

...jogo['home_team']...

外部int电话无效。

Python列表索引json错误
