How do you calculate?

[Guy Sheffer]

Yep, I use python too, I usually have an open terminal. And also my
Nokia N810 has python on it. So its really useful (simpler than even
opening the TI83 emulation or pulling out my scientific calculator
from deep in my bag).

And I might add, I use it quite a lot as a student when I need to do
something quick.
