python 2 字典的基本使用

dicVisit={}

if not  dicVisit.has_key(visitKey):#不存在
    diaSet = set()
    diaSet.add(diagnoseContent)
    dicVisit[visitKey]=diaSet
    #print ("new==="+visitKey + "-----"+diagnoseContent)
else:
    #取出字典中對應元素值，是個 set,並將診斷加進去
    originalDiaSet=dicVisit[visitKey]
    # for item in originalDiaSet:
    #     print item
    originalDiaSet.add(diagnoseContent)

 

遍歷：

  for key in dicVisitList.keys():
        valueDic = dicVisitList[key]
        jsonData.append(valueDic)
        print(valueDic)
