An equivalent python program might be:

	a b

It, like the perl code above, doesn't compile.

Python code which does what the perl code is probably meant to do
could be:

import sys
f = open(sys.argv[1])
for line in f:     #f.readlines() in older pythons
    #process something here, such as:
    print line,

A dictionary would be of much more use than a concordance,
googling for 

	perl python dictionary

actually gives a match, by pure chance, since what you
really want is a "phrasebook' by the title of the match.
