python如何將json格式的數據快速的轉化成指定格式的數據呢？或者轉換成sql文件？
下面的例子是將json格式的數據準換成以#_#分割的文本數據，也可用于生成sql文件。
[root@bogon tutorial]# vi json2txt.py #-*- coding: UTF-8 -*-import jsondata = []with open('./tencent_test.json') as f: for line in f: data.append(json.loads(line))#print json.dumps(data, ensure_ascii=False)import codecsfile_object = codecs.open('tencent.txt', 'w' ,"utf-8")str = "/r/n"splitstr = "#_#"for item in data: #print json.dumps(item) #str = str + "insert into tencent(name,catalog,workLocation,recruitNumber,detailLink,publishTime) values " #str = str + "'%s','%s','%s','%s','%s'/r/n" % (item['parentTitle'],item['parentLink'],item['author'],item['link'],item['title']) #print json.loads(item['author']) + "/r/n" str = "%s#_#%s#_#%s#_#%s#_#%s/r/n" % (item['parentTitle'],item['parentLink'],item['author'],item['link'],item['title'].strip()) file_object.write(str)#import codecs#file_object = codecs.open('tencent.txt', 'w' ,"utf-8")#file_object.write(str)file_object.close()print "success"注：如果數據量過大不宜全部放在str里一次性寫入文件?？梢钥紤]逐行寫入，或者到達一定程度時批量寫入。
另外：python通過strip(rm)替換字符串，當rm為空時，默認刪除空白符（包括'/n', '/r', '/t', ' ')。
