What is the best way to open a file as read/write if it exists, or if it does not, then create it and open it as read/write?
(如果文件以读/写方式打开,或者以不存在的方式创建,然后以读/写方式打开,最好的方法是什么?)

should do this, right? (根据我的阅读, file = open('myfile.dat', 'rw')
应该这样做,对吗?)
It is not working for me (Python 2.6.2) and I'm wondering if it is a version problem, or not supposed to work like that or what.
(它对我不起作用(Python 2.6.2),我想知道这是否是版本问题,或者不应该那样工作或做什么。)
The bottom line is, I just need a solution for the problem.
(最重要的是,我只需要解决这个问题。)
I am curious about the other stuff, but all I need is a nice way to do the opening part. (我对其他东西很好奇,但是我所需要的只是做开始部分的好方法。)

IOError: no such file or directory.
(IOError:没有这样的文件或目录。)
