problem:import csv data

[守株待兔]

import sqlite3 
con = sqlite3.connect('/home/stock.db')
cur = con.cursor()
cur.execute('''CREATE TABLE quote (ticker TEXT,date TEXT, popen TEXT, high TEXT, low TEXT,vol TEXT,adjclose TEXT);''')
i=/tmp/data.csv
cur.execute('.separator "," ')
cur.execute('.import  %s  quote'  %  i)
con.commit()
cur.close()
con.close()

the output is :
    cur.execute('.separator"," ')
sqlite3.OperationalError: near ".": syntax error

how to fix it?
