Yes! That is exactly what I was searching for. That helps a lot to me.
I already searched for everything that has anything to do with modules,
but I never ran across __import__(). It seems that I am searching not
effectively enough. I am not very familiar with python, so can you give
some tips on how to search for functions or modules to use, when I have
a specific problem to solve? What I mean is, you have helped me, but
without this list, I would have never found this solution. At what
places should one look, when he is searching for existing functions or
language features or the "python way" doing some things, aside from this
list of course. ;-)
