That's not a relative path, that's an absolute path.

var1 is not a relative path. It is an absolute path. Absolute paths start
with a drive letter like C. Relative paths have no drive letter and start
in the current working directory.

I am afraid I have no idea what your code is doing. Instead of describing
what your Python code isn't doing, can you show the code so we can see what
it is doing?

And please use variable names that mean something.

# terrible variable names
var, var1, var2

# good variable names
directory_name, full_path, filename

That works perfectly for me:

py> import os
py> cwd = os.getcwd()
py> path = os.path.join(cwd, "my_file")
py> print path
/home/steve/my_file


What were you expecting it to do? Can you tell us what result you expected,
and what result you got?
