If you need that strings retrieved from your sqlite database be returned as UTF-8 instead of Unicode, set-up your connection accordingly using the text_factory propery:

import sqlite3
class class1:
def __init__(self):
    self.print1()
def print1(self):
    con = sqlite3.connect('mydb.sqlite')
    con.text_factory = str
    cur = con.cursor()
    cur.execute("select fname from tblsample1 order by fname")
    ar=cur.fetchall()
    print(ar)

class1()

See this for the details: http://docs.python.org/library/sqlite3.html#sqlite3.Connection.text_factory

That takes care of the "u" in front of your strings. You'll then have to convert your list of tuples to a list:

ar=[r[0] for r in cur.fetchall()]
