Rewrite the list of lambda functions created in Example E4.10 using a single list comprehension.
The list comprehension:
flist = [lambda x, i=i: x**i for i in range(4)]
creates the same list of anonymous functions as that in Example E4.10. Note that we need to pass each i in to the lambda function explicitly or else Python's closure rules will lead to every lambda function being equivalent to x**3 (3 being the final value of i in the loop).
