TKinter通过循环运行

Question

对于一个基本示例，假设我要运行一个问题列表，并且对于每个问题，我都希望按下一个按钮，该按钮会将值“是”或“否”添加到列表中。

window = tk.Tk()
app=tk.Frame(window)
app.grid()

response_list = []

y_button = tk.Button(app,text="yes", command=lambda x="yes": appendResponse(x))

n_button = tk.Button(app,text="no", command=lambda x="no": appendResponse(x))

questions=["q1","q2","q3"]

window.mainloop()

如何使窗口保持打开状态并显示所有问题，直到有完整的答案列表？

Answer 1

您可以编写如下函数：

#STARTS HERE
#Label with question
lbl1 = tk.Label(app, text="Are you a human?")
lbl1.grid()

def appendResponse(resp):
    global response_list

    questionNo = len(response_list)

    if questionNo % 3 == 0:
        lbl1.configure(text="Is this a valid question?")

    elif questionNo % 3 == 1:
        lbl1.configure(text="Is there a better way to do this?")

    elif questionNo % 3 == 2:
        lbl1.configure(text="Is this what you wanted to do?")

    response_list.append(resp)

#FINISHES HERE
