Use os.path: basename() and dirname() instead of split()

According to Python documentation[1] dirname and basename
are defined as follows:
    os.path.dirname() = os.path.split()[0]
    os.path.basename() = os.path.split()[1]
For the purpose of better readability split() is replaced
by appropriate function if only one part of returned tuple
is used.
