Python EasyGUI – 是 否 框

Yes No Box :用于在 EasyGUI 中显示一个窗口有两个选项 yes 或 no，它可以用于需要以 yes 或 no 的形式得到问题答案的地方，它显示两个选项 yes 或no 例如，当我们想询问用户天气他是否在 18 岁以上时，我们将使用 yes no 框，类似于继续取消框，下面是继续取消框的外观

In order to do this we will use ynbox method

Syntax : ynbox(message, title, choices)

Argument : It takes 3 arguments, first string i.e message/information to be displayed, second string i.e title of the window and third is list having exactly two values which is two option for yes and no

Return : It returns True is yes is pressed else False

例子 ：
在此我们将创建一个是否框，当按下任何按钮时，它将在屏幕上显示特定消息，下面是实现

# importing easygui module
from easygui import *
  
# message / information to be displayed on the screen
message = "Are you a Geek ?"
  
# title of the window
title = "GfG - EasyGUI"
  
# creating a yes no box
output = ynbox(message, title)
  
  
# if user pressed yes
if output:
      
    # message / information to be displayed on the screen
    message = "Thats Great !!"
   
    # title of the window
    title = "GfG - EasyGUI"
   
    # creating a message box
    msg = msgbox(message, title)
  
# if user pressed No
else:
      
    # message / information to be displayed on the screen
    message = "You should become a Geek, go to GeeksforGeeks to become one"
   
    # title of the window
    title = "GfG - EasyGUI"
   
    # creating a message box
    msg = msgbox(message, title)
      
     

输出 ：

另一个例子 ：
在此我们将创建一个是否框并为是和否按钮设置特定选择，当按下任何按钮时，它将在屏幕上显示特定消息，以下是实现

# importing easygui module
from easygui import *
  
# message / information to be displayed on the screen
message = "Are you a Geek ?"
  
# title of the window
title = "GfG - EasyGUI"
  
# choices for yes and no button
choices = ["Agree", "Disagree"]
  
# creating a yes no box
output = ynbox(message, title, choices)
  
  
# if user pressed yes
if output:
      
    # message / information to be displayed on the screen
    message = "Thats Great !!"
   
    # title of the window
    title = "GfG - EasyGUI"
   
    # creating a message box
    msg = msgbox(message, title)
  
# if user pressed No
else:
      
    # message / information to be displayed on the screen
    message = "You should become a Geek, go to GeeksforGeeks to become one"
   
    # title of the window
    title = "GfG - EasyGUI"
   
    # creating a message box
    msg = msgbox(message, title)
      
     

输出 ：
