Python Cookie点击器：自动点击功能？

Question

我的背景： 我已经用python做了很多编程，我可以说我还不错。我熟悉大多数模块，OOP编程和其他东西。你可以查看我的pastebin配置文件，查看我的实际级别：www.pastebin.com/u/GameNationRDF/

代码：

from tkinter import *
import time

master = Tk()

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

def info():
    print ("Double click purchases need 750 clicks!")

info()

click = 0
mult = 1
dcp1 = 0

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

def purchaseDoubleClicksCommand():
    global click
    global mult
    if click < 750:
        print ("Not enough clicks!")
        blankLine()
    elif click >= 750:
        mult = mult*2
        click = click - 750
        print ("Double Clicks Purchased!")
        blankLine()

def buttonCommand():
    global click
    global mult
    click += 1*(mult)
    uiPrint()

    if click == 100:
        print ('''Achievement Unlocked: Junior Clicker!
    BONUS 100!''')
        click += 100

    elif click == 400:
        print ('''Achievement Unlocked: Little Ninja Clicks!
    BONUS 200!''')
        click += 300

    elif click == 900:
        print ('''Achievement Unlocked: Legit Ninja!
    DOUBLE CLICKS!''')
        mult = mult * 2

    elif click == 1500:
        print ('''Achievement Unlocked: Click Ninja Master!
    QUAD CLICKS!''')
        mult = mult * 4

    elif click == 3000:
        print ('''Achievement Unlocked:  Jackie Chan Style!
    8 TIMES THE CLICKS!''')

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

purchaseDoubleClickButton = Button(master, text="Purchase Double Clicks", command = purchaseDoubleClicksCommand)
purchaseDoubleClickButton.pack()


master.title("Clicker! v0.0.6")
master.geometry("%sx%s+%s+%s" % (200,70,512,512))
mainloop()

我需要一种方法，能够添加一个自动点击，将添加一定数量的饼干在给定的时间。我想按一下按钮就可以买到。但我没法让它工作

有什么帮助吗？谢谢：）
