Add the results for x in range

Question

k=5
for k in range (5,10):
    print(2*k**2)

50
72
98
128
162

I need to add these results.

Answer 1

Using list comprehension, would be:

soma = sum(2*k**2 for k in range(5, 10))

Read: for each value of k in the interval range(5, 10) calculate 2*k**2 and add up all the results.

Answer 2

You can do it like this:

soma = 0
for k in range (5,10):
    soma += 2 * k ** 2
    print(2 * k ** 2)

print(soma)
