如何更新 python 中的标签？

Question

我是 python 的新手，当我遇到问题时正在创建一个小游戏。我搜索了一个答案，找到了一个，但它没有用。

我正在尝试制作的游戏或多或少是 Cookie Clicker 的娱乐，我正在尝试制作我有更新分数的标签，相反，它创建了一个新标签。

from tkinter import *
import time

master = Tk()

def uiPrint():
print("")
print(click)
blankLine()

click = 0
mult = 1
dcp1 = 0

def blankLine():
    for i in range(20):
        print("") 

def buttonCommand():
    global click
    global mult
    click += 1*(mult)
    uiPrint()
scoreCommand = Button(text=click)
scoreCommand.pack()

mainClickButton = Button(master, text="Click me!", command = buttonCommand)
mainClickButton.pack()

master.title("Cookie Clicker")
photo = PhotoImage(file=r"C:\Users\---\Desktop\Cookie.gif")
label = Label(image=photo)
label.image = photo
label.pack()
mainloop()

我找到这个 post :

Update Tkinter Label from variable

稍微修改一下，意思是：

from tkinter import *

master = Tk()

def uiPrint():
    print("")
    print(clickcount)
    blankLine()

clickcount=0
click=StringVar() #Updates label if changed
click.set("0");
mult = 1
dcp1 = 0

def blankLine():
    for i in range(20):
        print("") 

def buttonCommand():
    global clickcount
    global click
    global mult
    clickcount += 1*(mult)
    click.set(str(clickcount)); #Update score
    uiPrint()

mainClickButton = Button(master, text="Click me!", command = buttonCommand)
mainClickButton.pack()

master.title("Cookie Clicker")
photo = PhotoImage(file=r"C:\Users\---\Desktop\Cookie.gif")
label = Label(image=photo)
label.image = photo
label.pack()

l = Label(master, textvariable = click) #Score
l.pack()

mainloop();

我还建议将 cookie 图像制作为按钮：

from tkinter import *

master = Tk()

def uiPrint():
    print("")
    print(clickcount)
    blankLine()

clickcount=0
click=StringVar() #Updates label if changed
click.set("0");
mult = 1
dcp1 = 0

def blankLine():
    for i in range(20):
        print("") 

def buttonCommand():
    global clickcount
    global click
    global mult
    clickcount += 1*(mult)
    click.set(str(clickcount)); #Update score
    uiPrint()

photo = PhotoImage(file=r"C:\Users\---\Desktop\Cookie.gif")
mainClickButton = Button(master, image=photo, command = buttonCommand)
mainClickButton.pack()

master.title("Cookie Clicker")

l = Label(master, textvariable = click) #Score
l.pack()

mainloop();

两者均使用 python 2.7.11 和 python 3.5.2 进行了测试，它们工作正常
