How did you conclude that? "diff -u %s %s > %s.patch" % (
src, dst, file ) is a Python expression, and will do what you
want!<br><br>
See
<a href="http://docs.python.org/lib/typesseq-strings.html" eudora="autourl">http://docs.python.org/lib/typesseq-strings.html</a>
for the official documentation.<br><br>
<blockquote type=cite class=cite cite="">but I couldn't figure out a way to <br>

I have been looking and couldn't discover string constructor such as<br><br>
command_string = string( "diff -u %s %s > %s.patch" % ( src, dst, file ) )<br><br>
From the documentation on docs.python.org, the closest is string <br>
Template (but my python installation doesn't come with this module). Any <br>
insights on initializing string in this manner?<br><br>
<br>
Thanks, Gilbert.<br>
