A pathname _is_ just a string. Presumably the problem is that you're
getting the results of os.listdir, which are just the names of the
contents of the directory, not the relative paths to them:
max at oxygen:~/tmp% mkdir subdir
max at oxygen:~/tmp% touch subdir/a subdir/b subdir/c
max at oxygen:~/tmp% ls subdir
a b c
max at oxygen:~/tmp% python

>>> import os
>>> os.listdir('subdir')
['a', 'b', 'c']
So just join the paths:
>>> for f in os.listdir('subdir'):
... p = os.path.join('subdir', f)
... print p, os.path.isfile(p)
...
subdir/a 1
subdir/b 1
subdir/c 1
