首先，正如@furas所提到的，睡眠是一个错误的选择，所以记住在tkinter中使用after来表示时间延迟！

此外，请记住构造代码（link#1、link#2），不要试图在一行中放置不必要的多个语句。

对于可移动按钮，最好使用Canvaswidget而不是任何布局管理器（除非您的真正目标是可移动按钮）。将按钮连续两次随机放置很容易，但如果要模拟移动，则不需要一组新的随机坐标，而需要一组旧坐标、随机距离（偏移）和随机方向。

使用place可以实现这一想法，但是有一种甜美的move方法可以为您完成所有这些。

所有你需要的是将每个按钮在画布与create_window（它也给你对象ID来控制你的小部件在画布上）和模拟大规模移动！

import tkinter as tk

class App(tk.Tk):
    def __init__(self, difficulty, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.difficulty = difficulty
        self.play_area = tk.Canvas(self, background='bisque')
        self.play_area.pack(expand=True, fill='both')
        self.animals = self.generate_animals()
        self.play()

    def play(self):
        #   move all animals continuously (each 100 ms)
        self.move_animals()
        self.after(100, self.play)

    def generate_animals(self):
        #   generate all button-like animals
        animals = [Animal('deer', self, text='DEER')]

        for _ in range(self.difficulty * 2):
            animals.append(Animal('doe', self, text='DOE'))

        return animals

    def move_animals(self):
        #   move all animals
        for animal in self.animals:
            animal.move()


class Animal(tk.Button):
    def __init__(self, animal_type, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.animal_type = animal_type
        self.base_speed = self.master.difficulty
        self.play_area = self.master.play_area
        self.move_sets = ['n', 's', 'w', 'e']

        #   place button on canvas (it's possible to randomize starting locations)
        self.id = self.play_area.create_window(0, 0, window=self)

        self.configure(command=self.kill)

    def move(self):
        #   move animal
        #   get random speed and direction
        distance = random.randint(0, 15) * self.base_speed
        direction = random.choice(self.move_sets)

        if direction in self.move_sets[:2]:
            if direction == 'n':
                distance *= -1

            #   to prevent case when an animal leaves play area
            if 0 <= self.play_area.coords(self.id)[1] + distance <= self.play_area.winfo_height():
                self.play_area.move(self.id, 0, distance)

        else:
            if direction == 'w':
                distance *= -1

            #   to prevent case when an animal leaves play area
            if 0 <= self.play_area.coords(self.id)[0] + distance <= self.play_area.winfo_width():
                self.play_area.move(self.id, distance, 0)

    def kill(self):
        if self.animal_type == 'deer':
            print('You shot the deer!')
        else:
            print('You shot a doe!')
            print('The rest of the herd have trampled you to death')
            print('Oh deer!')

        self.master.destroy()

app = App(difficulty=2)
app.mainloop()

正如你所看到的，它以某种方式起作用。

然而，还有很大的改进和调整空间。例如，“更平滑”的运动。虽然这取决于我们移动物体的距离，但也取决于帧速率，对于人类物种，帧速率为24 fps（高帧速率）。再次感谢after，我们可以通过延时控制该参数，延时可以通过公式time\u delay=1000//desired\u fps计算：

...
    def play(self):
        #   move all animals continuously
        self.move_animals()
        self.after(41, self.play)        #    24 fps
        #   self.after(33, self.play)    #    30 fps
...

还可以通过附加方向改进移动，并将条件逻辑简化为一条语句：

...
class Animal(tk.Button):
    def __init__(self, animal_type, *args, **kwargs):
        super().__init__(*args, **kwargs)
        ...
        #   dictionary for representation purpose
        self.move_sets = {'n': (0, -1), 's': (0, 1), 'w': (-1, 0), 'e': (1, 0),
                          'nw': (-1, -1), 'sw': (-1, 1), 'ne': (1, -1), 'se': (1, 1)}
        ...

    def move(self):
        #   move animal
        #   get random distance and direction
        distance = random.randint(0, 5) * self.base_speed
        direction = random.choice(list(self.move_sets.values()))
        movement = [_ * distance for _ in direction]
        current_coords = self.play_area.coords(self.id)

        #   to prevent case when an animal leaves play area
        if 0 <= current_coords[0] + movement[0] <= self.play_area.winfo_width() and \
           0 <= current_coords[1] + movement[1] <= self.play_area.winfo_height():
            self.play_area.move(self.id, *movement)
        ...
