帮我看看这个程序错误

#!/usr/bin/env python
import MySQLdb, pp, time
import MySQLdb.cursors
conn = MySQLdb.connect (host = "192.168.1.254",user = "root",passwd = "000000",db = "test",cursorclass = MySQLdb.cursors.DictCursor)
cursor = conn.cursor()
#two=conn.cursor()
#two.execute ("select * from slevin")
sql="select * from slevin"
#row=two.fetchall()
ppservers = ("192.168.1.254",)
#ppservers = ("10.0.0.1",)
ncpus=2
job_server = pp.Server(ncpus, ppservers=ppservers)
#job1 = job_server.submit(sum_primes, (100,), (isprime,), ("math",))
def count(sql,n):
         i=1
         while i<=n:
               cursor.execute(sql)
start_time = time.time()
job1 = job_server.submit(count, (sql,1000000,), (cursor.execute,), ("MySQLdb",))
print "Time elapsed: ", time.time() - start_time, "s"
cursor.close ()
conn.close ()

运行之后出现一下错误：
Traceback (most recent call last):
  File "./test.py", line 20, in ?
    job1 = job_server.submit(count, (sql,1000000,), (cursor.execute,), ("MySQLdb",))

都提示在哪里错了，可以去那里看下是否缺少什么文件？
python2.3？分传统yeah！
