porting python script from linux to windows

[hokieghal99]

What are the specific steps that one should take to make a python script
that works on a Linux x86 machine also work on a Windows x86 machine?

I am using os, re and string in the script. How do paths differ between
the two OSes? I am use to a unix-like path /blah/blah/blah. Would I need
to change this to x:\blah\blah\bl ah where x = drive letter? What about
creating fs objects? file works the same on both? os.walk works the same?

Thanks for the advice!!!

Instead of using full paths, try using the os.path.join method. It makes
it easier to port from/to any OS.

Check for platform dependencies in the documentation of all modules that
you use.

I'm currently developing an app on Windows and testing it for production
on Linux. I use os.path.join() to construct pathnames and have encountered
no portability problems.

Yes. But note the advice about binary files in the documentation of the
open()/file() builtin function.

It works :-)

You woudn't *need* to; the drive letter can be omitted when the file
is on the same drive. Also, Windows doesn't care what kind of slashes
you use (except for cmd.exe).

But you will have to, for example, change "/home/dan" to
"c:\\winnt\\Doc uments and Settings\\dan".

For the most part, yes, but in mind that, on Windows, it matters
whether you open a file in text or binary mode.

Yes.

Run it, and see what happens. ;-) Seriously, in theory there is no reason why
it shouldn't work right out of the box, unless you have platform-specific code.
So I'd say, just run it and see if you encounter any problems.

Maybe. Paths with slashes can be used on Windows as well.

Files should work the same, except that on Windows opening files in 'binary
mode' is different from 'text mode'. os.walk should work just fine.

HTH,
