【Python】python读写txt和json文件

 python读写txt和json文件

1、往txt文件中写入内容

# write txtimport osname =['a','b','c','d']seq=['11111','22222','33333','44444']        output_dir = '/home/cqh/faceData'emb_filename = os.path.join(output_dir, 'emb_txt.txt')with open(emb_filename, "w") as f:    for i in range(0, len(name)):        f.write(name[i] + "\t" + seq[i] + "\n")    f.close()

     运行结果如下：

2、从txt文件中读取内容

# read txtemb_filename = '/home/cqh/faceData/emb_txt.txt'fr = open(emb_filename)for line in fr.readlines():      print(line)

      运行结果如下：

3、往json文件中写入内容

# write jsonimport osname_emb = {'a':'1111','b':'2222','c':'3333','d':'4444'}        output_dir = '/home/cqh/faceData'   emb_filename = os.path.join(output_dir, 'emb_josn.json')jsObj = json.dumps(name_emb)  with open(emb_filename, "w") as f:    f.write(jsObj)    f.close()

     运行结果如下：

4、从json文件中读取内容

# read jsonemb_filename = '/home/cqh/faceData/emb_josn.json'fr = open(emb_filename)model=json.load(fr)for i in model.keys():    print('key: %s   value: %s' % (i, model[i]))

      运行结果如下;
