python system subprocess win32

Hello ALl,
I have a compiled program "conv.exe" that works as follows:

>>conv.exe

-----------------------------
Please selection from the following options. press "h" for help, "p" for
print, "r" for readfile.
Enter your request now:
....
--------------------
Is there a way to script python using the subprocess method to start this
program "conv.exe" and then send a "r" to the command line to make it, say,
readfile.

I have tried the following but the .communicate("r) is not doing anything

import subprocess
import time

a=subprocess.Popen("c:\\mcml\\conv.exe")
time.sleep(1)
(stdout, stderr) = a.communicate("r")

Many thanks,
Bryan

Use the sys.argv method. In the code that you have compiled, put the
following lines in:

<code>

import sys
default = sys.argv[1]
if default:
# check which option it is and run it appropriately
else:
# print your menu here

</code>

Then you should be able to do the subprocess Popen command:

subprocess.Popen("c:\\mcml\\conv.exe r")

You may need to turn the shell on...

subprocess.Popen("c:\\mcml\\conv.exe r", shell=True)

Hopefully that gives you some ideas anyway.

At the moment, I cannot figure a way of running this precompiled "conv.exe"
using commandline arguments.

Thus, I need Python to call the program, wait until it loads up, then enter
a known sequence of characters so that the function will run.
The program conv.exe I call looks like this.
--------------------------
Welcome to conv.exe
This program was written by ....

Please select from the following options: h- (help) r- (read) ...etc
Enter your request:
---------------------------------
I need Python to start the program, wait a second and then issue a few
characters to the program.

Hope this makes more sense!

Oh. I thought you had compiled the program yourself. I suppose you
could use SendKeys then. I have a couple links here:

http://pythonlibrary.org/python/SendKeys

It's pretty hackneyed, but I've used the SendKeys module to automate
Firefox to some degree.
