1. python 學習**
(老王python)
2. 通過commandline 執行 .py 指令碼
首先要將python的安裝目錄加入到path環境變數中。如:
path=%path%;c:\python27再到你儲存py原始檔的目錄下執行:
《指令碼路徑》 python
helloworld.py
3. python 通過命令列傳引數
例項:
import sys
if(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 實現socket通訊(tcp)
例項:(在2.7上測試通過)
server 端**:
client端**:import socket
address1=('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',address
cs.send('hello i am server,welcome')
while 1:
ra=cs.recv(512)
print ra
5. python 發郵件**:import socket
address=('127.0.0.1',2011)
s=socket.socket()
s.connect(address)
data=s.recv(512)
print 'the data received is/n ',data
s.send('hihi i am client')
while 1:
sinput=raw_input("enter message and send to server:\n")
s.send('from client: %s'%sinput)
6. python 獲取本機計算機名和ipimport 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 = 'huichanglee@163.com'
gmailpassword = '******'
recipient = 'cheers.lee@foxmail.com'
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:
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')
方法一:
方法二:import socket
name=socket.gethostname()
print name
ip_addr=socket.gethostbyname(name)
print ip_addr
7. pyhton 網路程式設計之多執行緒from socket import socket, sock_dgram, af_inet
s = socket(af_inet, sock_dgram)
s.connect(('google.com', 0))
print s.getsockname()

vim 學習積累(一)
首先是簡單的認識了三種狀態 大家公認的說法是模式 分別是 插入,檢視,和一般。進入vim之後預設的是一般模式,這時直接使用 a i o 也就是進入vim之後直接按下a i o鍵均可進入插入模式。其中的區別是,a命令會另游標後退乙個字元,然後進入插入模式。i是直接進入插入模式,游標位置不變。o會另游標...
