How to convert sqlite3 to csv format using API for a chatbot?

问题

When I run my chatbot it creates a db.sqlite3 file in backend for storing all the conversation. I want to convert this db.sqlite3 file into a csv file using API. How should I implement it in python? The image contains the type of file.

There are multiple tables in the db file associated with Chatterbot. They are conversation_association, conversation, response, statement, tag_association and tag.
Out of all these tables only response and statement tables have proper data (at least in my case). However I tried to convert all tables into csv. So you may find some empty csv files too.

import sqlite3, csv
db = sqlite3.connect("chatterbot-database")  # enter your db name here
cursor = db.cursor()
tables = [table[0] for table in cursor.execute("select name from sqlite_master where type = 'table'")]  # fetch table names from db

for table in tables:
    with open('%s.csv'%table, 'w') as fd:   
        csvwriter = csv.writer(fd)
        for data in cursor.execute("select * from '%s'"%table):  # get data from each table
            csvwriter.writerow(data)
