Python 学习积累《一》

 1. Python 学习网址

2. 通过commandline 执行 .py 脚本

首先要将python的安装目录加入到PATH环境变量中。如：
PATH=%PATH%;c:\python27再到你保存py源文件的目录下执行：
<脚本路径>   python  helloworld.py

3. Python 通过命令行传参数

http://www.cublog.cn/u3/107101/showart_2247117.html

实例：

import sysif(len(sys.argv)>2):    print "aaaa"    sys.exit(0)print "Commandline parameter 1: ",sys.argv[1]print "Commandline parameter 2: ",sys.argv[2]

4. Python 实现socket通讯（TCP)

http://blog.csdn.net/sunboy_2050/article/details/5969480

实例：（在2.7上测试通过）

Server 端代码：

import socketaddress1=('127.0.0.1',2011)s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.bind(address1)s.listen(5)cs,address = s.accept()print 'got connected from',addresscs.send('hello I am server,welcome')while 1:    ra=cs.recv(512)    print ra

Client端代码：

import socketaddress=('127.0.0.1',2011)s=socket.socket()s.connect(address)  data=s.recv(512)print 'the data received is/n    ',datas.send('hihi I am client')while 1:    sInput=raw_input("Enter message and send to server:\n")    s.send('From client: %s'%sInput)

5. Python 发邮件代码：

import os   import smtplib   import mimetypes   from email.MIMEMultipart import MIMEMultipart   from email.MIMEBase import MIMEBase   from email.MIMEText import MIMEText   from email.MIMEAudio import MIMEAudio   from email.MIMEImage import MIMEImage   from email.Encoders import encode_base64     def sendMail(subject, text, *attachmentFilePaths):       gmailUser = '[e-mail]'      gmailPassword = '******'      recipient = '[e-mail]'        msg = MIMEMultipart()       msg['From'] = gmailUser       msg['To'] = recipient       msg['Subject'] = subject       msg.attach(MIMEText(text))         for attachmentFilePath in attachmentFilePaths:           msg.attach(getAttachment(attachmentFilePath))         mailServer = smtplib.SMTP('smtp.163.com', 25)       mailServer.ehlo()       mailServer.starttls()       mailServer.ehlo()       mailServer.login(gmailUser, gmailPassword)       mailServer.sendmail(gmailUser, recipient, msg.as_string())       mailServer.close()        print('Sent email to %s' % recipient)     def getAttachment(attachmentFilePath):       contentType, encoding = mimetypes.guess_type(attachmentFilePath)         if contentType is None or encoding is not None:           contentType = 'application/octet-stream'        mainType, subType = contentType.split('/', 1)       file = open(attachmentFilePath, 'rb')         if mainType == 'text':           attachment = MIMEText(file.read())       elif mainType == 'message':           attachment = email.message_from_file(file)       elif mainType == 'image':           attachment = MIMEImage(file.read(),_subType=subType)       elif mainType == 'audio':           attachment = MIMEAudio(file.read(),_subType=subType)       else:           attachment = MIMEBase(mainType, subType)       attachment.set_payload(file.read())       encode_base64(attachment)         file.close()         attachment.add_header('Content-Disposition', 'attachment',   filename=os.path.basename(attachmentFilePath))       return attachment  # start to test   sendMail('Hi,Cheers Li', 'Greetings from lihuichang')  

 6. Python 获取本机计算机名和ip

方法一：

import socketname=socket.gethostname()print nameip_addr=socket.gethostbyname(name)print ip_addr

方法二：

from socket import socket, SOCK_DGRAM, AF_INET  s = socket(AF_INET, SOCK_DGRAM)  s.connect(('google.com', 0))  print s.getsockname() 

7. Pyhton 网络编程之多线程
