运行给定的Python SQLite3数据库操作程序，输出的结果是什么？
import sqlite3
conn = sqlite3.connect('t1.db')
cursor = conn.cursor()
conn.execute("DELETE from user")
cursor.execute('insert into user (id, name) values ('1', '张三')')
cursor.execute('insert into user (id, name) values ('2', '李四')')
cursor.execute('insert into user (id, name) values ('3', '王二')')
cursor.execute('insert into user (id, name) values ('4', '刘五')')
conn.commit()
cursor.execute('select id,name from user')
values = cursor.fetchone()
values = cursor.fetchone()
print(values)
cursor.close()
conn.close()
