Agreed, that's definitely a good rule of thumb. But there's still some
value in keeping the code length down too. In a program I maintain at
work (in C++, but the same holds true), some functions have a perfect
elevator talk, yet are quite a few screenfuls of code - this is not
really advisable. For instance, one function is "handle responses to
previously-sent requests". It incorporates all the code for handling
requests of type X, of type Y, and of type Z. If I were writing this
from scratch in Python, I would probably have X, Y, and Z all
separated out, and the checkresponses function would simply be a
dispatcher.
