May I request that you put your response at the end, or directly after 
whatever you're responding to.  What you did is called top-posting, and 
while it's common in private email, it's bad practice in these forums. 
It's also good to trim the parts that are no longer relevant, so the 
messages don't get too huge.  I'm guilty of omitting that step way too 

You have an example of os.path.join() in your own code, a few lines up. 
  But for this particular line, you could use

p = os.path.join(ruta, n[0], ".lprj")
