Hi,
I am tryiong to do something obviously trivial such as:
I have a c program called "tsys2list" that when it is ran it asks the user to give the value of "tcal" which is a variable. I
want to call the "tsys2list" from within a pyrthon script lets call it "gamma.py" >>>but<<< I want to pass
the value of "tcal" to th eprogram automatically and not by interacting with the keyboard.
How do I do that?
thanks i advance!

There are probably many ways to do this. I would recommend checking
out the subprocess module and see if it does what you want.
This will only work if the program can be fully controlled by
commandline arguments. If interaction is required, the OP might consider
using pexpect.
Or you
could learn a little Tkinter or wxPython and use that to get the
user's variable. Or you could even do it via the command line using
the "raw_input" command.
I fail to see how *gathering* input (regardless of the method) solves
the problem of *passing* input to a subprocess.

My understanding of the OP's request was that "tsys2list" was a custom
script of some sort that gathered info from the user, so I wanted to
know why he didn't just skip calling it and write something in Tkinter
or wxPython or even via the CLI instead.
I'm probably just not understanding something.
The program is doing some work, and needs to be told what actually to
do. It does so by asking the user, sure. But then it *works*. I think
that's pretty clear from
"""

So replacing it with something that asks the same questions leaves us
with the work undone...
