Python解ProjectEuler最大回文数问题

Python解ProjectEuler最大回文数问题

原题：
A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91  99.

Find the largest palindrome made from the product of two 3-digit numbers.

===============================
Python代码

Python代码 
max(reduce(lambda a,b:a+b,[ [k*i for k in range(i,1000) if str(k*i)==str(k*i)[::-1]] for i in range(100,1000)]))

顺便贴个第二题的Haskell解，感觉上第二题Python就没办法OneLine了
----------------------------------------
原题：
Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
----------------------------------------

暴力解：
Haskell代码 
sum $ filter even $ takeWhile (< 4000000) $ map fst $ iterate (\(a,b)->(b,a+b)) (1,2) 

貌似其它语言在不import的情况下都不方便直接秒掉
