Actually, os.path.join() is a simple function, there's nothing
Obejct-Oriented about it. "Everything is an object" simply means that
functions are objects, but that doesn't mean that the design of
everything is Object-Oriented.

Using the shell for this is the least cross-platform solution possible.
Python's libraries have very corss-platform implementations of such
operations you should use them!

In this case, it seems you're looking for os.listdir(dir_name). Just
call it with the path of a directory and it will return a list of names
of all the files and directories therein. You can use os.path.isdir(),
os.path.isfile(), etc. to figure out what type of file system object
each item in the list is. You can check premissions for the current
user with os.access(). Finally, you can find out more data about any
file with the "stat" module, which is more low-level.
