Right now, I have no clue, what the last line means. Maybe, it is a simple
python/urwid problem and you do not have to know the whole lfm code to give

Well, this error suggests that lfm is trying to use the result of the
exec statement as a function and call it. Perhaps the "act" string is
modified from what was in the dictionary -- you can get really strange
behaviours from code that does tricks with exec statements.
But a larger issue is that Urwid wasn't designed to be integrated
peicemeal into curses applications. It was designed to wrap curses.
One problem you'll run into is that Urwid sets up the curses palette and
remembers the colour pair indexes. In an existing curses application it
will have already set up the palette on its own, so it will take some
maneuvering to make colours work properly in Urwid. If you'd like to try
it, read the curses_display module source code to see how it stores the
attribute to colour pair mapping, and fill that data structure yourself.
It might not be the best project for introducing yourself to Python
programming, but it is possible.
Now, doing a complete Urwid version of lfm would be fun. But I'm sure
my idea of fun differs from most peoples' :-)
