def GetHtmlSource(url):
try:
htmSource = ''
req = urllib2.Request(url)
fd = urllib2.urlopen(req,"")
while 1:
data = fd.read(1024)
if not len(data):
break
htmSource += data
fd.close()
del fd
del req
htmSource = htmSource.decode('cp936')
htmSource = formatStr(htmSource)
return htmSource
except socket.error, err:
str_err = "%s" % err
return ""
3
通过GET的方法
def GetHtmlSource_Get(htmurl):
htmSource = ""
try:

【windows+python3.1.2】
发布python应用程序是个很麻烦的事,因为<1>无法编译原生code<2>每个版本的字节码不同<3>如果直接上源码会损害自己的利益——等等
方法1——手动打包
怎么打包呢?一个python文件夹要二十多MB啊!
yes!我们就要清理无用的东西!
先写一个win.py文件: ......
There should be one—--and preferably only one –--obvious way to do it.

#POP3
pop_client = poplib.POP3(pop3_server, port=server_port)
pop_client.user(user_name)
pop_client.pass_(passwd)
