python在使用star时更新值

Question

我想知道为什么我的值“player_action_input”没有得到更新。 值保持为0.我知道我可以使用（player_action_input）而不是（* info）但我想尝试学习如何使用*更新值。 ###如果我运行这个，我得到2个结果。

player_action_input = 0
info = [player_action_input]

def player_action(*info):    
    while True:   
        try:
            player_action_input = int(input("Enter 0 to stay, 1 to go Up, or 2 to go Down: "))
        except ValueError:
            print("You have entered an incorrect number, please try again")
            continue

        if player_action_input == 0:
            ready_speech(*info)         

        if player_action_input == 1:
            player_action_input = player_action_input + 1
            print ("Thank You, you chose to go up")
            count(*info)

        if player_action_input == 2:
            player_action_input = player_action_input + 2
            print ("Thank You, you chose to go down")
            count(*info)

        else:
            print ("You have entered an incorrect number, please try again")
            continue
        break

def count(*info):
    print (player_action_input)

player_action(*info)
