The following error keeps occuring in this function and others like it that are similar, I cannot seem to figure out why, does anyone have a solution?

def rare_func():
    rare_chance = random.randint(1, 151)
    if rare_chance < 91:
        rare = Rare_Rewards[3]
    elif rare_chance >= 106 and not rare_chance > 114:
        rare = Rare_Rewards[0]
    elif rare_chance >= 114 and not rare_chance > 146:
        rare = Rare_Rewards[4]
    elif rare_chance >= 146 and not rare_chance > 147 :
        rare = Rare_Rewards[2]
    elif rare_chance > 147:
        rare = Rare_Rewards[1]
    print("Opening...")
    pygame.time.wait(1000)
    ra_background = True
    print("")
    #pickup_audio.play()
    print("You got a [RARE] Chest and inside is: " + str(rare))
    #rare_audio.play()
    print("")

I tried adding the global variable which was a solution in another post with the same occurring issue and some other minor tweaks and expected it to entirely go away but like I said earlier it just keeps occurring randomly.
