Adding n different lists to list results same list repeating

Question

When I add lists to my list the result is list of correct length, but all the lists are the same, last list I added

code:

cycle_points = []
for i in range(games_per_cycle):
    points = game.game_cycle()
    print(points)
    cycle_points.append(points)
print(cycle_points)

When changing cycle_points = [] to cycle_points = [[] for n in range(games_per_cycle)] as suggested here, has no effect.

sample output:

[26.0, 26.0, 2.0, 22.0, 12.0]
[7.0, 23.0, 19.0, 1.0, 2.0]
[21.0, 28.0, 2.0, 12.0, 2.0]
[17.0, 26.0, 4.0, 25.0, 4.0]
[1.0, 30.0, 22.0, 15.0, 20.0]
[0.0, 19.0, 23.0, 6.0, 24.0]
[17.0, 15.0, 24.0, 2.0, 35.0]
[27.0, 5.0, 15.0, 17.0, 4.0]
[2.0, 24.0, 6.0, 26.0, 14.0]
[27.0, 11.0, 5.0, 12.0, 26.0]

[[27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0], [27.0, 11.0, 5.0, 12.0, 26.0]]

Your game object is recycling the same list. – Moses Koledoye Dec 26 '17 at 19:27 — Moses Koledoye, Dec 26 '17 at 19:27
I print the list it produces and it varies. – Arttu Hyvönen Dec 26 '17 at 19:36 — Arttu Hyvönen, Dec 26 '17 at 19:36
It's *still the same list*. It's always `self.points`, no? – juanpa.arrivillaga Dec 26 '17 at 21:08 — juanpa.arrivillaga, Dec 26 '17 at 21:08
