Concise is only worth so much.  PEP20 tells us "Explicit is better than
implicit", "Simple is better than complex" and "If the implementation is
hard to explain, it's a bad idea".

Python is a beautifully expressive language.  Your goal should not be to
write the minimum number of lines of code to accomplish the task. 
Your goal should be to write the code such that your grandmother can
understand it.  That way, when you screw it up, you'll be able to easily
figure out where and how you did so.  Or failing that, you can get
grangran to show you.
