Django学习笔记（三十六）:Django读取文件内容，并进行操作后，再写入文本

#先将所需操作的文件放置再static目录下的一个子目录下
_change_status_root = os.path.join(STATIC_ROOT,'player_status')
#mkdirs()是创建多级目录
mkdirs(_change_status_root)
#用于写入错误信息的error.txt
error_file_path = os.path.join(_change_status_root,'error.txt')
#用于读取所需操作信息的player.txt
push_file_path = os.path.join(_change_status_root,'player.txt')
