困扰点：python3中将文件写入到txt文件中，使用的方法与python2稍有不同：

python2 ：

        with open(file_path, 'wb') as f:
            f.write('ID:'+item['userid']+'\n')
            f.write('用户名:'+item['username']+'\n')
            f.write('省份:'+item['province']+'\n')
            f.write('城市:'+item['city']+'\n')
            f.write('内心独白:'+item['monolog']+'\n')
            f.write('学历:'+item['education']+'\n')
            f.write('生日年份:'+item['birthdayyear']+'\n')
            f.close()

python3：

        with open(file_path, 'wb') as f:
            # f.write('ID:%d' %int(item['userid'])+'\n')

            # 在python3的环境中进行向txt文件中写入字符串的操作时，需要以bytes的形式将我们的字符串写入到文件中，
            # 采用的方式为（f.write(bytes(string=yourString, '编码格式（如：utf-8)'))
            f.write(bytes('用户名：'+item['username'] +'\n', 'UTF-8'))
            f.write(bytes('省份：' + item['province'] +'\n', 'UTF-8'))
            f.write(bytes('城市：' + item['city'] +'\n', 'UTF-8'))
            f.write(bytes('学历：' + item['education'] +'\n', 'UTF-8'))
            f.write(bytes('内心独白：' + item['monolog'] +'\n', 'UTF-8'))
            f.write(bytes('生日：' + item['birthdayyear'] +'\n', 'UTF-8'))

            f.close()

谢谢大家！！
