1What do you think it would mean for i to be "actually" √-1? – user2357112 Apr 15 '17 at 23:47

Like most implementations of complex arithmetic, Python represents complex numbers by storing their real and imaginary components. Operations on complex numbers are implemented in terms of their components; for example, addition is performed componentwise, and multiplication is the standard FOIL multiplication you should be familiar with.
