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
