Jarek's answer is the correct one, for almost any real situation.

For the purposes of exposition, though, a pythonic equivalent would
be:

    import fileinput

    for l in fileinput.input():
        print l.replace('string1', 'string2')

If you want regular expression substitution and not just constant
strings, use re.sub instead.
