Most people use regular expression to do this sort of job. I don't know
python, but here is a perl example:

	foreach $filename (@array_of_filenames) {
		$filename ~=3D s/\..+$//;
		# $filename now contains new name. insert code to use new name here
	}

Perhaps someone who knows python would be kind enough to provide a python
example.

By the way, renaming files by removing a specific extension is easy in the
shell. To rename bunch of files named <name>.HTM to <name>.html, try

	for file in *.HTM; do
		mv $file `basename $file .HTM`.html
	done

But removing any extension regardless of its content requires fuzzy matchin=
g,
such as a regular expression.
