Question

在这种情况下，我要迭代self.players两次。对于每次迭代，我想在调用print方法之前暂停一秒钟。我怎样才能让他工作？这是一个简化的示例：

import tkinter as tk

class Main(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.players = [1, 2, 3, 4, 5]
        self.play()

    def play(self):
        for x in range(2):
            for player in self.players:
                self.after(1000, self.print, player)

    def print(self, player):
        print(player)

if __name__ == '__main__':
    Main()

直接控制计数器

self.after应该调用play方法，而不是print方法

import tkinter as tk

class Main(tk.Tk):
    def __init__(self):
         tk.Tk.__init__(self)
         self.counter=0
         self.players = [1, 2, 3, 4, 5]
         self.after(1000,self.play)

   def play(self):
         if self.counter<2:
             for player in self.players:
                 (self.print(player))
             self.counter+=1
             self.after(1000,self.play)

   def print(self, player):
         print(player)

if __name__ == '__main__':
   Main()

在Tkinter的for循环中创建暂停
