I see everybody's suggesting os.path.* solutions, and they're fine, but
an interesting alternative is os.walk:

__, thedirs, thefiles = os.walk('.').next()

thefiles is the list of filenames (and thedirs is the list of directory
names), and each is sorted alphabetically.  (I'm assigning to '__' the
absolute path of the current directory, meaning I intend to ignore it).
An expression that just provides the filename list is

  os.walk('.').next()[2]

although this may be a tad too obscure to recommend it!-)
