Answer 1

You're calling clean_up_bubs() before you define it in the first loop. Move the function definitions out of and above the while loop.

def get_coords(id_num):
    pos = c.coords(id_num)
    x = (pos[0] + pos[2])/2
    y = (pos[1] + pos[3])/2
    return x, y


def del_bubble(i):
    del bub_r[i]
    del bub_speed[i]
    c.delete(bub_id[i])
    del_bub_id[i]


def clean_up_bubs():
    for i in range(len(bub_id)-1, -1 , -1):
        x, y = get_coords(bub_id[i])
        if x < -GAP:
            del_bubble(i)


while True:
    if randint(1, BUB_CHANCE) == 1:
        create_bubble()
    move_bubbles()
    clean_up_bubs()
    window.update()
    sleep(0.01)
