Python例子二

例1、构造函数

#-*-coding:utf-8-*-
import sys
class Student:
    def __init__(self,name,age):
        self.__name=name
        self.__age=age
    def getName(self):
        format="my name is %s my age is %d"%(self.__name,self.__age)
        print format
    def __del__(self):
        print "del"
if __name__=="__main__":
   studeng=Student("chu",35)
   studeng.getName()

例二：静态成员与私有成员

#-*-coding:utf-8-*-
import sys
class A:
    y=2
    def __init__(self):
        self.x=1
        self.__z=1
if __name__=="__main__":
    a=A()
    print a.x
    print A.y
    print a.__z

例三：

#-*-coding:utf-8-*-
import sys
class A:
    def prt(self):
        print "my name is A"
    def reprt(self):
        A.prt(self)
if __name__=="__main__":
    a=A()
    a.prt()
    a.reprt()

例四：字典的散列查找

#-*-coding:utf-8-*-
import sys
if __name__=="__main__":
    dict={"a":"apple","b":"banana","g":"grape","o":"orange"}
    print dict
    print dict["a"]
    dict2={1:"apple",2:"banana",3:"grape",4:"orange"}
    print dict2
    print dict2[1]
