如何在python中更新标签? [英] How to update a label in python?

问题描述

我是python的新手，遇到问题时我正在创建一个小型游戏.我搜索了一个答案，找到了一个答案，但是没有用.

I'm new to python, and I was creating a small game when I got a problem. I searched for an answer, found one, yet it didn't work.

我要制作的游戏或多或少是对Cookie Clicker的重新娱乐，我正在尝试制作具有更新分数的标签，相反，它会创建一个新标签.

The game I'm trying to make is more or less a recreation of Cookie Clicker, and I'm trying to make the label which I have the score on update, instead, it creates a new label.

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()

推荐答案

我发现了这篇文章:

从变量更新Tkinter标签

稍微修改一下就意味着:

A bit modified this means :

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();

我另外建议将cookie图像制作为按钮:

I would additonaly suggest to make the cookie image as a button :

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();

两者都经过python 2.7.11和python 3.5.2的测试，它们可以正常工作

Both tested with python 2.7.11 and python 3.5.2, they work fine
