1.文本文件转 json 格式

　　读取 txt 文件中的 tweets 文本，将其转为 json 格式，可以打印输出，也可以提取详细信息

代码：

import json
import os

folderpath = r"D:\Twitter Data\Data\test"
files = os.listdir(folderpath)
os.chdir(folderpath)

# get the first txt file
tweets_data_path = files[0]

# store json format file in this array
tweets_data = []
tweets_file = open(tweets_data_path, "r")
for line in tweets_file:
    try:
        tweet = json.loads(line)
        tweets_data.append(tweet)
    except:
        continue
# print json format file with indentation
print(json.dumps(tweets_data[0], indent=4))

输出：
