Question

我的.json文件中的数据采用以下格式

[
    {
        "FIRSTNAME":"NAOMI","EMAIL":"HJHU@hiuj.com","ADDLINE":"jnjn","CITY":"hbiu",
        "FIRSTNAME":"gsf","EMAIL":"ghjujk@hn.com","ADDLINE":"kfjm","CITY":"hjhdjdyh",
        "FIRSTNAME":"sgbg","EMAIL":"aeth@aeth.com","ADDLINE":"dzfht","CITY":"sbfbg",
        "FIRSTNAME":"jkju","EMAIL":"ethe@th.com","ADDLINE":"tdhat","CITY":"dfhbdth",
    }
]

我希望将CITY附加到ADDLINE，重命名为ADDRESS并在.csv文件中更新。输出应为

[
    {
        "FIRST NAME":"NAOMI","EMAIL":"HJHU@hiuj.com","ADDRESS":"jnjn,hbiu",
        "FIRST NAME":"gsf","EMAIL":"ghjujk@hn.com","ADDRESS":"kfjm,hjhdjdyh",
        "FIRST NAME":"sgbg","EMAIL":"aeth@aeth.com","ADDRESS":"dzfht,sbfbg",
        "FIRST NAME":"jkju","EMAIL":"ethe@th.com","ADDRESS":"tdhat,dfhbdth",
    }
]

Answer 1

在Python的主页上查看JSON库的文档：https://docs.python.org/2/library/json.html

您需要加载json文件：

data=json.loads(file('json.json').read())

然后处理数据：

for row in data:
  row['ADDRESS'] = row['ADDRESS']+','+row['CITY']
  del row['CITY']

...然后将其写回文件：

file('json2.json','w').write(json.dumps(data))

当然，在您的最终解决方案中，请务必关闭您已打开的文件。

顺便说一句，您的示例不是有效的JSON文件，并且您提供的输出看起来更像JSON而不是CSV，尽管它也不是有效的JSON。所以，我假设您希望输出为JSON。

如果您确实希望输出为CSV，请阅读https://docs.python.org/2/library/csv.html

Answer 2

source_file = open('source.json', 'r')
output_file = open('output.csv', 'w')

for line in source_file:
    item = json.loads(line.strip())
    item['ADDRESS'] = "%s,%s" % (item['ADDRESS'], item['CITY'])
    del item['CITY']
    output_file.write(','.join(item.values()) + '\n')

source_file.close()
output_file.close()
