問(wèn)題描述

下面的是已經(jīng)用re.sub采集出來(lái)的了，需要在每個(gè) {} 前面加上 “1”： “2”： “3”，請(qǐng)問(wèn)該如何寫這個(gè)：

’{'nClass':-1,'nIcon':16}，{'nClass':-1,'nIcon':15},{'nClass':-1,'nIcon':14}’

最終效果：

’“1”：{'nClass':-1,'nIcon':16}，“2”：{'nClass':-1,'nIcon':15},“3”：{'nClass':-1,'nIcon':14}’

問(wèn)題解答

你描述的不夠清楚，你說(shuō)結(jié)果應(yīng)該是一個(gè)list,你是要轉(zhuǎn)換成dict嗎？

import jsonstr = ’{'nClass':-1,'nIcon':16},{'nClass':-1,'nIcon':15},{'nClass':-1,'nIcon':14}’lst = json.loads(’[{}]’.format(str))l = [’'{}':{}’.format(i+1, json.dumps(v)) for i,v in enumerate(lst)]print ’,’.join(l)回答2：

import redata = ’{'nClass':-1,'nIcon':16},{'nClass':-1,'nIcon':15}, {'nClass':-1,'nIcon':14}’# 提取為數(shù)組data = re.findall(’((?=,s?)?{.*?})+’, data)# 下標(biāo)從1開(kāi)始, 所以i+1print ’,’.join([’'%d':%s’ % (i+1, v) for i, v in enumerate(data)])# '1':{'nClass':-1,'nIcon':16},'2':{'nClass':-1,'nIcon':15},'3':{'nClass':-1,'nIcon':14}
