Wow, Jack, that is one awesome and simple module...thank you so much! I am happily storing and accessing all the arrays I could ever want :) Thanks to all for the quick assistance! On Fri, Mar 18, 2011 at 4:24 PM, Jack Trades wrote: > > On Fri, Mar 18, 2011 at 5:21 PM, Jon Herman wrote: > >>

Folks, thanks for the many responses! Specifying the full file name (and not using parentheses when inappropriate, thanks Jack :)) I am now happily reading/writing files. My next question: what is the best way for me to write an array I generated to a file? And what is the best way for me to load

Re: Reading/Writing files

For open() or os.open(), it should look in your Current Working Directory (CWD). Your python's CWD defaults to what the CWD was when python was started, and it is changed with os.chdir(). Absolute paths will of course be relative to / on most OS's (or C:/ if you're on C:, D:/ if you're on D:, etc

Jack, thanks. Alright, so what I did is create a file called hello.txt with a single line of text in there. I then did the following: f="fulldirectory\hello.txt" (where fulldirectory is of course the actual full directory on my computer) open("f", "w") And I get the following error: IOError: [E
