open file in dir independently of operating system

Hello,
I want to open the file 'configuration. smo' that is in directory dir.
Yet, I don't know on which os my program is being run. On Unix I would
say:

f = open(dir + '/configuration.s mo', 'r')

What is the os-independent version of this line?

(I have read the manual of the module os, but I didn't see how to do
it.)

I believe you want:

import os
f = open(os.path.jo in(dir, 'configuration. smo'), 'r')

....

*nix-heads everywhere?

For a text file, I would prefer:
f = open( os.path.join( dir , 'configuration. smo' ), 'U' )

and for a binary file:
f = open( os.path.join( dir , 'configuration. smo' ), 'rb' )

That way it also works on Windows.

Did You check this out on Windows? My experience with *nix paths is
that they work.
open("C:/bla.txt")

<open file 'C:/bla.txt', mode 'r' at 0x026B4A20>

hi, I'm working on a project spanning five .cpp files. each file was used to define a class. the first has my Main and an #include for each of the other files. problem is my third file needs to access the class defined in my second file and I can't figure out how to work this right. if I use an #include in my third file, my Main gives me a compile-time class redefinition error. if I don't, the third file can't "see" the second

For most users, this new feature is actually very convenient. If you want to control the update process,...
