When the list x is created it had eight items
[0, 1, 2, 3, 4, 5, 6, 7]
The first time through the for loop i is the first item in the list or 0.
The 0 is removed from the list which becomes
[1, 2, 3, 4, 5, 6, 7]
The second time the for loop sets i to the second item in the list which is now 2 not the original 1.
The 2 is removed and the list is now
[1, 3, 4, 5, 6, 7]
The third time though the for loop i becomes the third item in the list 4. The 4 is removed and the list is now
[1, 3, 5, 6, 7]
The fourth time through the for loop i becomes the fourth item in the list 6. The 6 is removed and the list becomes
[1, 3, 5, 7]
There is no fifth item in the list now so the for loop ends.

x.remove(i) removes the item i from the list not the item at index i. If you have a list x = [1,2,3,4,5,6,7]
x.remove(1) will remove the 1 at index 0 from the list, not the 2 from x[1].

To understand better print(i) and print(x) inside the loop you will get to know each and every step in the process.
