python遍历 truple list dictionary的几种方法总结

实例如下：

    def TestDic1():
      dict2 ={'aa':222,11:222}
      for val in dict2:
        print val

    def TestDic2():
      dict2 ={'aa':222,11:222}
      for (key,val) in dict2.items():
        print key,":",val   

    def TestList1():
      list=[1,2,3,4,5,3,2,'ada','fs3']
      for i in range(len(list)):
        print list[i]

    def TestDic3():
      dict2 ={'aa':222,11:222}
      print "###########iteritems#################"
      for k,v in dict2.iteritems():
        print "dict[%s]=" % k,v

    def TestDic4():
      dict2 ={'aa':222,11:222}
      print "###########iterkeys,itervalues#######"
      for k,v in zip(dict2.iterkeys(),dict2.itervalues()):
        print "dict[%s]=" % k,v    

    def TestList2():
      list=[1,2,3,4,5,3,2,'ada','fs3']
      for i in list:
        print i
