Question

I have a mission to convert sqlite3 data to Json format and CSV format, I can read the data like this (line breaks added):

Is there some tools or modules (import json?) that help me to transfer, and the most import thing is what are the formats about json and CSV, could you give me a example use the data above?

Just like, I create a dict {‘a’:dad,’b’:dada}, but in json format?

To convert to json, whether it’s one row or cursor.fetchall():

import json

json_data = json.dumps(data)

or use json.dump(some_file_object, data) if you want to store it to a file.

To convert to csv:

import csv

writer = csv.writer(some_file_object)

for row in cursor:
    # the csv module can't handle unicode, so encode the strings
    row = [item.encode('utf-8') if isinstance(item, basestring) else item 
                                                                for item in data]
    writer.writerow(row)
