python - 如何每n秒运行一个函数而不中断其他代码？也许在后台运行？

Question

Python 是我的第一语言，所以如果没有意义请理解我。我正在用 python 制作一个虚拟宠物。我使用 Tkinter 作为 GUI。我想每 5 秒运行一次 Action 类中的显示方法。但是，如果我使用线程、调度或时间并将代码放在按钮之前，它就会卡住并只运行显示方法。如何每 5 秒运行一次显示方法，同时不中断按钮和其他部分？

class Pet:    
def __init__(self, name, hunger=0, boredom=0, tiredness=0, sickness=False,
             age=0, waste=0):
    self.__name = name
    self.hunger = hunger
    self.boredom = boredom
    self.tiredness = tiredness
    self.sickness = sickness
    self.age = age
    self.waste = waste
    self.choice = choice

class Action(Pet):
    def __init__(self, name):
        Pet.__init__(self, name, hunger=0, boredom=0, tiredness=0,
                 sickness=False, age=0, waste=0)
        self.name = name

    def display(self):
        print("------------")
        print("hunger", self.hunger)
        print("boredom", self.boredom)
        print("tiredness", self.tiredness)
        print("sickness", self.sickness)
        print("age", self.age)
class Window(Frame):
    def openmenu(self):
        petname = self.petnameEntry.get()
        user_pet = Action(petname)
        print("I am your pet,", petname)
        window = tk.Toplevel(root)
        w = Label(window, text="What would you like to do?")
        w.pack()

        btFeed = Button(window, text="Feed", command=lambda: user_pet.eat())
        btFeed.pack(pady=3)
        btPlay = Button(window, text="Play", command=lambda: 
        user_pet.play())
        btPlay.pack(pady=3)

您可以使用After方法。

import tkinter as tk
root = tk.Tk()

class Pet:
    def __init__(self, name, hunger=0, boredom=0, tiredness=0, sickness=False,
                 age=0, waste=0):
        self.__name = name
        self.hunger = hunger
        self.boredom = boredom
        self.tiredness = tiredness
        self.sickness = sickness
        self.age = age
        self.waste = waste

class Action(Pet):
    def __init__(self, name):
        Pet.__init__(self, name, hunger=0, boredom=0, tiredness=0,
                 sickness=False, age=0, waste=0)
        self.name = name

    def display(self):
        print("------------")
        print("hunger", self.hunger)
        print("boredom", self.boredom)
        print("tiredness", self.tiredness)
        print("sickness", self.sickness)
        print("age", self.age)
        root.after(5000,self.display)

root.after(5000,Action(Pet).display)

root.mainloop()
