将收集的推文附加到列表时出错

Question

试图将收集到的推文内容存储到数据列表中。 但是遇到错误我不知道如何解决。

代码：

data=[]

import json

def string_to_json(line):
    import ast
    jsonval=ast.literal_eval(line)
    return jsonval

with open('tweetFile.json', encoding = 'utf-8') as f1:
    for line in f1:
        line=string_to_json(line)
        print(line['full_text'])
        data.append(json.loads(line))

错误：

---> 12         data.append(json.loads(line))

--> 341             raise TypeError(f'the JSON object must be str, bytes or bytearray, '
    342                             f'not {s.__class__.__name__}')
    343         s = s.decode(detect_encoding(s), 'surrogatepass')

TypeError: the JSON object must be str, bytes or bytearray, not dict

Answer 1

json.loads()可以直接加载字符串：

data=[]
import json

with open('tweetFile.json', encoding = 'utf-8') as f1:
    for line in f1:
        #print(line['full_text'])
        data.append(json.loads(line))
