Looks like Perl to me, what the heck are you thinking?  :)

def loadModules(self, path):
     self.modules.extend([
         __import__(os.path.splitext(m)[0])
         for m in os.path.listdir(path)
         if os.path.splitext(m)[1] == '.py' or 
os.path.exists(os.path.join(path, m, '__init__.py'))
     ])

This also has the advantage that it lets you use a package.  As with 
yours, path must be in sys.path.
