Multiplatform scripts: Can I avoid os.sep?

[gmax2006]

Hi,

I am developing scripts that must run on both Linux and windows.

My scripts contain lots of relative paths (such as log\\log.txt or
ctl\\table.ctl) If I use os.sep, it makes the code ugly. Is there any
tips or techniques to have Python automatically converts \\ to / when
the script runs on Linux? What is the best way to deal with this
situation?

Thank you,
Max

Use Jason Orendorff's path module:

http://www.jorendorff.com/articles/python/path/

Then you can do things like:

targetPath = 'some' / 'random' / 'path'

and the overridden '/' operator will do the right thing for the OS you
are on.
Of course, using the '/' operator in this manner makes some people's
heads explode.

os.path.join('l og', 'log.txt')
os.path.join('c tl', 'table.ctl')

Or look for the 'path' module

forward slashes work just fine on Windows too, in almost all cases.

(for the few cases when they don't work, use os.path.normpat h and
friends to fix them up).
