best way to check if a file exists?

[Michael S]

If you want to open the file for writing just open it
with append mode. open(¨filename", "a"). If it
doesn't exist - it'll create it, and if it does it'll
start appending to the file

For reading - os.path.exists("filename"). Or (doesn't
make much sense, but still) try to open it for reading
and python will throw an IOException which you can
catch and handle.
