Thanks, what is the idea behind storing the keys and values in a list, I assume
looking up for a value in a map is faster getting the value from the list.
Also I like the idea of combining multiple rows into one string and passing it.
I would batch up the million rows in to strings and give it a shot.

Reg Python Byte code
Dear All, Python 2.3 creates byte code with *.pyc extention. But Python 2.4 creates bytes code with *.pyo. Is there any difference between *.pyc and *.pyo?. Actually After python compiled a program then that program will run from the *.pyc byte code. If I delete that byte code what will be happen.? If I delete *.pyc byte code in the python 2.3 then It will create again *.pyc byte code. But If I delete *.pyo byte code in the python 2.4 then It will not create again *.pyo. Why this difference. If I delete byte code of the python. I want to know Whether it will affect the performance of the programme or not.

This code will build plain email message properly.
But after building the message. If a email user
download this mail through out look express then
this email message will display without any alignment.
If a user type 3 paragraph message
outlook express display as a single line. What
could be problem?. Kindly let me know ASAP

os.system('rm -rf test')

if directory is not present then I again try to

os.system('rm -rf test')
now this time also It will print
0

Regarding Mail sending smtplib Module
Dear All,
I have doubt regarding mail sending smtplib
module. The below code is I used to send a mail.
##
import email.Message
import email.Utils
import mimetypes
import os,string
fromAddr="[EMAIL PROTECTED]"
toAddr=
["[EMAIL PROTECTED]","[EMAIL PROTECTED]"]
mainMsg=email.Message.Message()
mainMsg["Date"]=email.Utils.formatdate(localtime=1)
mainMsg["Subject"]="en new contents"
mainMsg["From"]=fromAddr
mainMsg["To"]= string.join(toAddr,",")
## I am sending below message ## here
mainMsg.set_payload("Good to win win\n")
server = smtplib.SMTP('localhost')
server.set_debuglevel(1)
server.sendmail(fromAddr, toAddr, mainMsg.as_string())
server.quit()
##
This is the output of above send mail program.
Here I want to avoid this line "Received: from unknown
(HELO prabahar.enmail.com) (59.92.13.47) by
mailserver with SMTP; 11 May 2005 10:09:11 - " How
can I do this? . Why python give this line? . Mail
sending Module in php will not give this type line.
Here I have another doubt Php mail sending module give
MessageId automatically
but python doesn't set that. why?
output
