<p class=MsoNormal>Hello all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This is my first post to the <a
href="mailto:Tutor@python.org">Tutor@python.org</a> mailing list. I am in the
process of switching from Matlab to Python and there is one task that I am
having a hard time doing and cannot find the answer on the web. I want to write
a script in python that will open up a windows dos program, send three inputs (file
names) into program and then run it. I know one way to open up the dos program with
os.system(r”c:\shake91.txt”) but cannot do the rest.<o:p></o:p></p>

<p class=MsoNormal>And there is a blinking cursor after Name of Input File. At
this point I can manually enter in the file name (and the two other remaining
file names) and then press enter and the program does run. What I really want
though is to be able to do the whole thing with a python script.<o:p></o:p></p>
