【问题描述】:
我正在尝试从 OpenWeatherMap 转换我的 json 数据,但它一直给我错误。当我在其他教程网站上尝试其他 json 文件时,它工作得非常好。
Json 格式:
{
"cod": "200",
"message": 0,
"cnt": 40,
"list": [
{
"dt": 1586250000,
"main": {

}],
"clouds": {

},
"wind": {

},
"rain": {
"3h": 0.16
},
"sys": {

}
],
"city": {

"timezone": 28800,

}
}
我用 python 创建了一个函数,通过 api 调用读取 JSON 并使用 pandas 将其转换为数据帧
def _weather():
url = 'http://api.openweathermap.org/data/2.5/forecast?q=Singapore,{API}'
res = requests.get(url)
data = res.json()
return data
将其读取为 json 后,我尝试将其转换为数据帧,但收到错误
#df = pd.dataFrame(_weather)
df = pd.read_json(_weather)
我错过了什么步骤?
预期的数据帧如图所示, 我正在尝试显示 16 行数据,因为我正在为 16 天/每日预测提取数据。
【问题讨论】:
-
你能添加错误吗?
-
除了 Talha 的问题,请发布您预期的输出数据框

@sammywemmy,我已经添加了链接和图片
