How do I kill an empty file ??

[Greg Jorgensen]

Use the fileinput module:

----
import glob, fileinput
files = glob.glob("path/to/files/*.tab")  # get all file names

for filename in files:
    for line in fileinput.input(filename):
        if len(line) > 2:
            ... # process line
----

fileinput.input gives you an iterator over the lines in the file. It
ignores empty files (opens and closes them immediately), so they won't
be processed by your code.
