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
