Both routines above produce identical output -- full path/filenames.
Neither prints just a directory name.

File "p2.py", line 23, in ?
for line in fileinput.input(f,):
File
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/fileinput.py",
line 231, in next
line = self.readline()
File
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/fileinput.py",
line 320, in readline
self._file = open(self._filename, "r")
This looks similar to before -- fileinput.input() still isn't operating
on the input.
Again, I'm looking 1) walk through all files in a directory tree and 2)
using fileinput, evaluate and possibly edit the files.
The current version of the program is below.
thanks!
