Your args are fine, that's just the way os.path.walk works. If you
just need the absolute pathname of a directory when given a relative
path, you can always use os.path.abspath, too.
A couple more examples that may help, using os.walk:
>>> for i in os.walk('/var/log'):
... for j in i[1] + i[2]:
... print os.path.join(i[0], j)
...
/var/log/apache2
/var/log/cups
/var/log/fax
/var/log/krb5kdc
/var/log/ppp
/var/log/sa
/var/log/samba
Or, in the event that a relative path was used:
>>> for i in os.walk(os.path.abspath('../../var/log')):
... for j in i[1] + i[2]:
... print os.path.join(i[0], j)
...
/var/log/apache2
/var/log/cups
/var/log/fax
/var/log/krb5kdc
/var/log/ppp
/var/log/sa
/var/log/samba
