[kirby urner]

Lets remember also about dict and set comprehensions.

List comprehensions get all the press.

These are indeed giving the same lists:

print([(4*n**2 + 4*n)//4 for n in range(50)])
print([sum(range(0, 2*i, 2)) for i in range(1, 50)])

[0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156, 182, 210, ...]
[0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156, 182, 210, ...]
