Python выделение пути и имени файла

# python
import os.path

myPath = '/Users/t/web/perl-python/I_Love_You.html'
(dirName, fileName) = os.path.split(myPath)
(fileBaseName, fileExtension)=os.path.splitext(fileName)

print dirName # /Users/t/web/perl-python
print fileName # I_Love_You.html
print fileBaseName # I_Love_You
print fileExtension # .html

if not filePath:
    filePath = '../data'

fileName = QFileDialog.getOpenFileName (
