Today is 2017-05-03, here are some basic methods of using Python. There is no sorrow in the world that cannot be shed, and this sorrow cannot be explained to others, even if it is explained. It is always static, such as no wind at night snowflakes quietly deposited in the bottom of my heart.
Python Basics Learning One, Python functions as parametersIi. python referencing a custom moduleImport Math def Add (x, Y, f): return f (x) + f (y)print# 8.0
Define two files huhx.py and huhx5.py under the same directory. Where huhx.py is used as a module for huhx5.py.
# defined a module " Linux " def saymyname (): Print ("", username)Import huhxhuhx.saymyname ();
#write the file, which is generally used to write shorter charactersWith open ('.. /file/huhx.xml','W', encoding='Utf-8') as F:f.write ('Hello, huhx!.')
#The read of the file, which is typically used to read short charactersWith open ('.. /file/huhx.xml','R', encoding='Utf-8') as F:Print(F.read ())
Iv. stmtp simple Email in python
ImportSmtplib fromEmail.headerImportHeader fromEmail.mime.textImportMimetext fromEmail.utilsImportparseaddr, Formataddrdef_format_addr (s): Name, addr=parseaddr (s)returnFormataddr (Header (name,'Utf-8'). Encode (), addr) from_addr='****'Password='*****'to_addr='******'Smtp_server='smtpcom.263xmail.com'msg= Mimetext ('Hello, my name is HUHX.','Plain','Utf-8') msg[' from'] = _FORMAT_ADDR ('HUHX <%s>'%from_addr) msg[' to'] = _FORMAT_ADDR ('Linux <%s>'%to_addr) msg['Subject'] = Header ('Subject Info','Utf-8'). Encode () server= Smtplib. SMTP (Smtp_server, 465) Server.set_debuglevel (1) server.login (from_addr, password) server.sendmail (from_addr, [to_addr], msg.as_string ()) Server.quit ()
If you are sending an HTML message, change the above msg to the following:
msg = Mimetext ('' + ' ) <p>send by <a href= "http://www.python.org" >Python</a>...</p> ' + '</body>'html' 'utf-8')If you need to send an attachment:
ImportSmtplib fromEmailImportencoders fromEmail.headerImportHeader fromEmail.mime.baseImportMimebase fromEmail.mime.multipartImportMimemultipart fromEmail.mime.textImportMimetext fromEmail.utilsImportparseaddr, Formataddrdef_format_addr (s): Name, addr=parseaddr (s)returnFormataddr (Header (name,'Utf-8'). Encode (), addr) from_addr='****'Password='*****'to_addr=' * * *@qq. com'Smtp_server='smtpcom.263xmail.com'#Mail object:msg =Mimemultipart () msg[' from'] = _FORMAT_ADDR ('Hello <%s>'%from_addr) msg[' to'] = _FORMAT_ADDR ('HUHX <%s>'%to_addr) msg['Subject'] = Header ('Subject Info','Utf-8'). Encode ()#the message body is Mimetext:Msg.attach (Mimetext ('send with File ...','Plain','Utf-8'))#Adding an attachment is to add a mimebase that reads a picture from the Local:With open ('Huhx.png','RB') as F:#set the MIME and file name of the attachment, here is the PNG type:MIME = Mimebase ('Image','PNG', filename='Test.png') #Add the necessary header information:Mime.add_header ('content-disposition','Attachment', filename='Test.png') Mime.add_header ('Content-id','<0>') Mime.add_header ('X-attachment-id','0') #read the contents of the attachment in:Mime.set_payload (F.read ())#code with BASE64:Encoders.encode_base64 (MIME)#Add to Mimemultipart:Msg.attach (MIME) server= Smtplib. SMTP (Smtp_server, 465) Server.set_debuglevel (1) server.login (from_addr, password) server.sendmail (from_addr, [to_addr], msg.as_string ()) Server.quit ()
V. Simple HTML parsing in Python
fromHtml.parserImportHtmlparserclassMyhtmlparser (htmlparser):defHandle_starttag (self, Tag, attrs):Print("encountered a start tag:", Tag)defHandle_endtag (self, tag):Print("encountered an end tag:", Tag)defHandle_data (self, data):Print("encountered some data:", data) parser=Myhtmlparser () parser.feed ('' '<body>')
The results of the operation are as follows
Friendship Linkencountered a start tag:htmlencountered a start tag:headencountered a start tag:titleencountered some data : Te Stencountered an end tag:titleencountered an end tag:headencountered a start tag:bodyencountered a start Tag:h1encou ntered some data : Parse me! encountered an end tag:h1encountered a end tag:bodyencountered an end tag:html
