What's the easiest and quickest way to execute a compiled C "command
line interface" program THROUGH Python?

I don't know what you mean by THROUGH. But the subprocess, popen2 and
os-modules deal with calling other programs. Try them in that order.

import subprocess
subprocess.call ("cmd")

Thanks. Can anyone provide an example of using *subprocess* to run
helloWorld.C through the python interpreter.

compile helloWorld, and run:

import subprocess
subprocess.call ("helloWorld ")

(any special reason why you couldn't figure this out yourself, given the
example provided by gsteff ?)

No. You can't run a .C file. You can run a .exe file (I'm
guessing you're using Windows based on the question).

If my experience is anything to go by it just means there won't be a

Unless you have a C interpreter installed. e.g.:

import os
os.system("eic helloWorld.C")

(Requires eic to be in your PATH.)

I doubt it's what the OP was looking for, though.

There is a reason (though it is not special). I'm new to Python. I
looked at all the documentation on subprocess, as well as popen. I
couldn't figure it out, so I thought an example (which I thank you for
providing) would help me along (which it did). Is there a special
reason for you having a problem with me asking for help? I thought
that's what this group is for.

as I noted in the part of my reply that you didn't read, the person you replied to
(gsteff) also provided an example. Since his post didn't contain any other text, I
did find it a bit strange that you missed that part of his message, but still managed
to reply to it.

Re: Execute C code through Python

So i generated the .exe file "myFile.exe "

This is a Windows - text based application. Right now, when I run:

import subprocess
subprocess.call ("myFile")

the application starts in its own console window. Is there a way for
it to run inside the python interface?

Thanks,

[Peter Hansen]

Google found the following (after I read the docs for subprocess and
learned about the "startupinf o" flag, and searched for "subprocess
startupinfo"). Does this help?

Thanks Peter! That's exactly what I need.
