Tip on the "Late Binding Closures" section

The two solutions in "What You Should Do Instead" are certainly correct, while there's another solution in that special case, one can simply change

return [lambda x : i * x for i in range(5)]

to

return (lambda x : i * x for i in range(5))

in other words, one can create a generator, rather than a list, to postpone the time when cell contents be evaluated. Actually, a more essential test code could be

for multiplier in create_multipliers():
    print multiplier.__closure__[0].cell_contents

FYI.

Read the "Late Binding Closures" section, especially "What You Should Do Instead," and compare the proposed generator example with the existing explanations. Run the supplied create_multipliers() loop to verify the closure behavior. Done means the documentation accurately presents any valid alternative and includes a clear supporting example.
