import sqlite3
conn=sqlite3.connect("test.db")
c=conn.cursor()

c.execute('''CREATE TABLE stocks(data text,trans text,symbol text,qty real,price real)
''')
c.execute("""INSERT INTO stocks VALUES('2017-01-05','BUY','RHAT',100,35.14)""")
conn.commit()
conn.row_factory=sqlite3.Row
c=conn.cursor()
c.execute('SELECT * FROM stocks')
r=c.fetchone()
print(type(r))
print(tuple(r))
print(r[2])
print(r.keys())
print(r['qty'])
for field in r:
  print(field)
c.close()
