I want the function to display heads or tails(randomly).我希望 function(随机)显示正面或反面。 Instead, the function displays nothing and ignores the function. I have also tried printing the value instead of displaying it on tkinter, but it only shows heads and not tails.
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。 If any additional details are needed to solve my issue please comment and I will provide additional details.
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。
In the function open_coin
, when the button coin
is clicked, you are creating the label
but not specifying the x and y coordinates in place
, and that too creating everytime the button is pressed.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。 So, create a label to display the result and keep changing its text using config
.因此,创建一个 label 来显示结果并使用
config
不断更改其文本。
And the random
function is called only once, so keep it inside the flip
function to call everytime in order to get a new random coin value.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)
