Python: Time a code segment for testing performance (with timeit)
- by Mestika
Hi,
I've a python script which works just as it should but I need to write the time for the execution. I've gooled that I should use timeit but I can't seem to get it to work.
My Python script looks like this:
import sys
import getopt
import timeit
import random
import os
import re
import ibm_db
import time
from string import maketrans
myfile = open("results_update.txt", "a")
for r in range(100):
rannumber = random.randint(0, 100)
update = "update TABLE set val = %i where MyCount >= '2010' and MyCount < '2012' and number = '250'" % rannumber
#print rannumber
conn = ibm_db.pconnect("dsn=myDB","usrname","secretPWD")
for r in range(5):
print "Run %s\n" % r
ibm_db.execute(query_stmt)
query_stmt = ibm_db.prepare(conn, update)
myfile.close()
ibm_db.close(conn)
What I need it the time it takes the execution of the query and written to the file "results_update.txt". The purpose is to test an update statement for my database with different indexes and tuning mechanisms.
Sincerely
Mestika
