[英]Why is my Tkinter button not executing my function?

我希望 function(随机)显示正面或反面。 相反,function 什么都不显示,并忽略了 function。我也尝试打印该值而不是在 tkinter 上显示它,但它只显示正面而不显示反面。 如果需要任何其他详细信息来解决我的问题,请发表评论,我将提供其他详细信息。
在 function open_coin
中,单击coin
按钮时,您正在创建label
但未指定 x 和 y 坐标place
并且每次按下按钮时也会创建。 因此,创建一个 label 来显示结果并使用config
不断更改其文本。
而random
数 function 只被调用一次,所以将其保存在flip
function 中,每次都调用以获得新的随机硬币值。

CoinLabel = Label(c_wn, text="") #will be used to display the result
CoinLabel.place(relx=0.5, rely=0.2, anchor='s')
def flip():
coin_values = ["Heads", "Tails"]
coin_face = random.choice(coin_values)
print(coin_face)
if coin_face == "Heads":
CoinLabel.config(text="Coin: Heads")
else:
CoinLabel.config(text="Coin: Tails")
coin = Button(c_wn, text='coin', padx=100, pady=90, command=flip)
coin.place(relx=0.5, rely=0.5, anchor=CENTER)
