我有一个名为"panamaleaks50k.json"的json文件.我想从json文件中获取['text']字段,但它显示我跟随错误

JSON对象必须是str,bytes或bytearray,而不是'TextIOWrapper'

这是我的代码

with open('C:/Users/bilal butt/Desktop/PanamalEakJson.json','r') as lst:
    b = json.loads(lst)
    print(b['text'])

我的json文件看起来

 }
]

我如何阅读所有['text']和单个['text']字段？

我有数据帧total_year,其中包含三列(年,动作,喜剧).

total_year

我想在X轴上绘制年份列,在Y轴上绘制(动作和喜剧).

我如何在Y轴上绘制两列(aciton和喜剧).这是我的代码.它在Y轴上仅绘制1列.

total_year[-15:].plot(x='year', y='action' ,figsize=(10,5), grid=True  )

我有12列的火车数据集。

我想根据Pclass列的值1 选择Cabin列的行，然后用1替换Cabin列的选定行的值。

train['Cabin'] =train[train['Pclass']==1]['Cabin']=1
