List comprehensions

Question

Hello Ducks.

I didn't understand the List comprehensions, can anyone explain me the following code, please.

------ CODE ------
cubes = [i**3 for i in range(5)]
print(cubes)

------ OUTPUT ------
[0, 1, 8, 27, 64]

Answer 1

same as:

cubes = []
for i in range(5):
cubes.append(i**3)

Answer 2

Slick if someone put i * 3. what is the value of i at the beginning before the miltiplication ?

Answer 3

and what about:

for i in my_list:

what it i equal to ?

Answer 4

what is my_list?

Answer 5

I copied and pasted your code "Slick" but it doesn't print anything.

Answer 6

yeah its cause i didnt tell it to. add the line:

print(cubes)

Answer 7

yes, I know. I didn't see the whole code.

Answer 8

but yeah "i ** 3" what is the value of i ?

Answer 9

it says for i in range(5).
so i is 0,1,2,3, and 4

Answer 10

It depends wich iteration youre on.

for i in range(5):

makes i equal to a number between 0-4. I would mess around and print loops so you can see how they work.
