我想处理此文件并获取一些信息并使用它填充CSV文件。为此，我使用以下内容：
import unicodecsv
import json
json_data = open("test.json")
data = json.load(json_data)
f = unicodecsv.writer(open("results.csv","wb+"))
for entry in data:
if "merchantApplication" in entry:
ma = entry["merchantApplication"]
if "email" in ma:
f.writerow([ma["ownerFirstName"],ma["ownerLastName"],ma["email"],ma["legalName"],ma["businessAddress"],ma["businessAddress2"],ma["businessCity"],ma["businessCountry"],ma["businessState"],ma["businessZip"],ma["phone"],ma["mobile"]])
json_data.close()
此工作正常但不打印列上方的标题。如何添加标题？我使用的是Python 2.7.10
答案 0 :(得分：2)
如何添加标题？
很简单，在f.writerow((<your>,<headers>,<here>))循环之前调用for。
