Pygame not rendering 3d cube well

Question

I am trying to build a rotating 3d cube without using any external python 3d module. This is my code:

import pygame

WIDTH, HEIGHT = 700, 500

win = pygame.display.set_mode((WIDTH, HEIGHT))

WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
GREEN = (0, 255, 0)

points = [
    [100, 100],
    [200, 100], 
    [100, 200],
    [200, 200],

    [100, 100],
    [200, 100], 
    [100, 190],

    [100, 100],
    [200, 100], 
    [100, 190],

    [100, 100],
    [200, 100], 
    [100, 190]
]

joining = [
    (0, 1),
    (0, 2),
    (1, 3),
    (2, 3),
    
    (1, 4),
    (2, 6),
    (4, 6),

    (4, 7),
    (6, 9),
    (7, 9),

    (7, 10),
    (9, 12),
    (10, 12)

]

run = True

while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    win.fill(WHITE)

    if points[0][0] <= points[3][0]:
        points[0][0] += 0.1
        points[2][0] += 0.1
        points[3][1] -= 0.03
        points[6][1] += 0.009

    elif points[4][0] <= points[0][0]:
        points[4][0] += 0.1
        points[6][0] += 0.1
        points[2][1] -= 0.03
        points[9][1] += 0.009

        points[1][0] -= 0.1
        points[3][0] -= 0.1
        points[3][1] += 0.001

    else:
        points[7][0] += 0.1
        points[9][0] += 0.1
        points[6][1] -= 0.03
        points[12][1] += 0.009


    for point in points:
        pygame.draw.circle(win, BLACK, point, 2)

    for join in joining:
        pygame.draw.line(win, BLACK, points[join[0]], points[join[1]])

    pygame.display.flip()

pygame.quit()

The cube is not working fine. Can i have a more efficient way of drawing this cube in python without using any external module like OpenGl or something like that. Running the code is advised to check what i am saying.
