Town Field Poem:
Cheng listens to the Tathagata language, the world name and benefit of Dayton. Be willing to do the Tibetan apostles, the broad show is by Sanfu mention.
I would like to do what I learned, to achieve a conscience blog. May all the Yimeimei, reproduce the wisdom of the body.

Code
Class MyClass: def __init__ (self,long,weight): self.long=long self.weight=weight #两个对象的长相加, The width is unchanged. Returns a new class def __add__ (self,others): return MyClass (self.long+others.long,self.weight+others.weight) #两个对象的宽相减, long unchanged. Returns a new class def __sub__ (self,others): Return MyClass (Self.long-others.long, Self.weight-others.weight) #说一下自己的参数 def intro (self): print ("Long", Self.long, "width as", self.weight) a= MyClass (10,5) A.intro () B=myclass (20,10) B.intro () C=b-ac.intro () D=a+bd.intro ()
Result
The ============= restart:c:\users\administrator\desktop\mycode.py ============= length is 5 wide for a width of 10 long for a width of ten 5 length is 30
