Python TKinter Gui: Toplevel window
#from pp3e Chapter 9.3
#############################################################################
# popup three new window, with style
# destroy() kills one window, quit() kills all windows and app; top-level
# windows have title, icon, iconify/deiconify and protocol for wm events;
# there always is an app root window, whether by default or created as an
# explicit Tk() object; all top-level windows are containers, but never
# packed/gridded; Toplevel is like frame, but new window, and can have menu;

万恶的编码
小菜对于老师上一节讲的不是很明白，因为没有一本书是将文件与web一起讲授的，他决定自己探究一下它们之间的不同：
首先，小菜在C盘建了一个文本文档 file.txt,输入四个字：我是小菜。
然后，小菜在shell中练习起来：
>>> file=open("c:\\file.txt","r")
>>> data=file.read()

python的变参
*args和**dargs是Python的两个可
变参数，两者有所不同的是*args是个tuple，**dargs是个dict。
*args
和**dargs并用时，*args必须放在**dargs的前面。
例如：
def func(a,b, *c):
pass
函数func至少有两个参数变参数放在tuple c中
def func(*c): 或者 def func(**d ......

与堆栈类似，通过python的列表类型来实现，参考 help(list)
shoplist=['apple','mango','carrot','banana']
print 'I have',len(shoplist),'items to purchase'
print 'these items are:'
for item in shoplist:
print item,
shoplist.append('rice')
print 'my shopping list is now', shoplist
shoplist. ......
