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? From what I read,
file = open('myfile.dat', 'rw') should do this, right?
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.
The bottom line is, I just need a solution for the problem. I am curious about the other stuff, but all I need is a nice way to do the opening part.
The enclosing directory was writeable by user and group, not other (I’m on a Linux system… so permissions 775 in other words), and the exact error was:
IOError: no such file or directory.
You should use
open with the
file = open('myfile.dat', 'w+')
