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**:
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
client端**:
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)
5. python 發郵件**:
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 = '[email protected]'
gmailpassword = '******'
recipient = '[email protected]'
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')
6. python 獲取本機計算機名和ip
方法一:
import socket
name=socket.gethostname()
print name
ip_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()

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...
