我正在尝试在一些YouTube教程的指导下学习Visual Basic.他们建议使用Microsoft Visual Studio Express 2013,因为它具有内置编译器.我遇到了一个问题,我的屏幕左侧的工具箱栏是空的.有谁知道如何解决这一问题？ http://gyazo.com/328ade3754613c971dd6d4745a0ed171这是我截图的链接.

我想问一下如何在python中创建一个"LIVE"文本框？该程序是自动售货机的模拟器(下面的代码).我希望有一个显示实时信用更新的文本框你如何在tkinter中做到这一点？

例如:假设在窗口中间有一个信用卡,其中包含0.当10p按下按钮,对信贷的框应该从"0"更改为"0.10".有没有可能在tkinter和python 3.3.2中做？先感谢您!

import sys
import tkinter as tk

credit = 0
choice = 0

credit1 = 0
coins = 0
prices = [200,150,160,50,90]
item = 0
i = 0
temp=0
n=0
choice1 = 0
choice2 = 0

credit1 = 0
coins = 0
prices = [200,150,160,50,90]
item = 0
i = 0
temp=0
n=0
choice1 = 0
choice2 = 0

def addTENp():
    global credit
    credit+=0.10

def addTWENTYp():
    global credit
    credit+=0.20

def addFIFTYp():
    global credit
    credit+=0.50

def addPOUND(): …

代码：

import sys
from tkinter import *

credit = 0
coins = 0
choice = 0


credit1 = 0
coins = 0
prices = [200,150,160,50,90]
item = 0
i = 0
temp=0
n=0
choice1 = 0
choice2 = 0

credit1 = 0
coins = 0
prices = [200,150,160,50,90]
item = 0
i = 0
temp=0
n=0
choice1 = 0
choice2 = 0

def insert():
    insert = Tk()

    insert.geometry("450x250")
    iLabel = Label(insert, text="Enter coins.[Press Buttons]").grid(row=1, column=1)

    tenbutton = Button(insert, text="10p").grid(row=2, column=1) …
