cubes = [i**3 for i in range(5)]
So here is what it does. The code takes values of i in the range(5) meaning it will take 0, 1, 2, 3, 4.
Now, for each value that it takes it puts it in the variable i then it does i**3 which is the cube of i, or i*i*i if you want. And when it gets that result it adds it to the list cubes.
So:
First: i = 0, then it does i**3 = 0 * 0 * 0 = 0 and add it to the list
Second: i = 1, then it does i**3 = 1 * 1 * 1 = 1 and add it to the list
Third: i = 2, then it does i**3 = 2 * 2 * 2 = 8 and add it to the list
Fourth: i = 3, then it does i**3 = 3 * 3 * 3 = 27 and add it to the list
Fifth: i = 4, then it does i**3 = 4 * 4 * 4 = 64 and add it to the list
So cubes contains 0 1 8 27 64

It's a for loon.
Range(5)= 0,1,2,3,4
i**3= i to the power 3
For using "for" loop.
it means:
0^3=0
1^3=1
2^3=8
3^3=27
4^3=64
