在python中将.csv文件转换为.json格式

我已将数据收集到csv文件中，数据如下所示：

1)username;date;retweets;favorites;text;geo;mentions;hashtags;id;permalink
2)CFSharing;2017-05-27 01:59;0;0;"£5 million raised for Manchester bombing victims in just three days #love http:// crowdfunding.einnews.com/article/383427 730/5ppRHGKOfQkNtAFM?ref=rss&ecode=SQUvWbWCp_PWzTRB …";;;#love;"868255418203557888";https://twitter.com/CFSharing/status/868255418203557888
3)TracksuitDavid;2017-05-27 01:58;1;0;"Tony Blair has been eerily silent on the Manchester bombing .

第一行包含列名，其余行是数据

如何将数据转换为json文件，该文件如下所示：

1)username;date;retweets;favorites;text;geo;mentions;hashtags;id;permalink
2)CFSharing;2017-05-27 01:59;0;0;"£5 million raised for Manchester bombing victims in just three days #love http:// crowdfunding.einnews.com/article/383427 730/5ppRHGKOfQkNtAFM?ref=rss&ecode=SQUvWbWCp_PWzTRB …";;;#love;"868255418203557888";https://twitter.com/CFSharing/status/868255418203557888

注意：数字

1）

，

2）

，

3）

表示行号

这可以使用Python完成，如下所示：

import csv
import json

with open('input.csv', 'rb') as f_input, open('output.json', 'w') as f_output:
    first = True

    for row in csv.DictReader(f_input, delimiter=';'):
        if first:
            f_output.write('{')
            first = False
        else:
            f_output.write(',\n')
        json.dump(row, f_output)

    f_output.write('}') 

可能的副本。
