An equivalent in modern Pythons:
>>> print ''.join(line.expandtabs(3) for line in file('h071.txt'))
In short: expandtabs is a method on strings, there's no need to seek to the
beginning, and files are closed when they are garbage collected (although I
can't make myself not close output files after years of doing so), and map()
is largely deprecated in favor of list comprehensions and generator
functions.
