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

自从小白上完第一课，Python简直成了他的科学计算器。每天早上，小白总是不忘“练习”一下Python。

前两天理解了unicode、utf-8、gb2312这些编码之间的关系以后，今天终于弄明白了在python里面的编码问题。我们在写python脚本时如果有中文的字符串，在运行的时候有可能会报错也有可能会出现乱码。一般加上# -*- coding:utf-8 -*-就不会报错了，但是还可能有乱码问题，而且同样的代码在不同的编辑器中得出的结果 ......
1，编写Server.py
import socket
s=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
s.bind(('localhost',8081))
while True:
data,addr=s.recvfrom(1024)
print 'receive:',data,'from',addr
2，编写Client.py
import socket
s=socket.socket(socket.AF_INET,socket.SOC ......
前言：
最近又想学习python,又想去温习一下算法，于是就想出了这个两不误的方法,^_^
堆栈：
使用python的列表结构，详情可以查看help(list)
#Filename: stack.py
shoplist=['apple','mango','carrot','banana']
shoplist.append('rice')
popitem=shoplist[-1]
del shoplist[-1]
print 'the popitem is',popitem
......
队列：
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. ......
