Description
因为同时在两个文件夹写代码，所以工作目录与当前执行的main.py不一定是同一个目录。
有时候，想要打开main.py同目录下的tang300.json文件，写open('tang300.json','r')会报错找不到文件，因为工作目录是另一个文件夹。
想了一个办法如下：
location = sys.argv[0] #获取main.py的路径
location = location.rstrip('main.py') + 'tang300.json' #获取同目录下tang300.json的路径
但是这个方法看起来呆呆的...
想问一下：
除了这样写以外，有什么更简洁的方法打开与main()同目录文件夹下的文件？
搜索引擎的一个方法是修改工作目录，不过好像这也看起来呆呆的...大家都是一个文件夹下的文件，应该有很简单的打开办法吧？
