How to construct this function

[nana pink]

I am trying to construct a function called maxSquare. In which it takes a list of integers X and returns Xi with the maximum square value, without using loops.

Sample Input/Output

>>> maxSquare([5, ‐7, 3])
-7


If you coul help me with this, I would appreciate it.

Thanks in advance.

Here's one way of doing it without using a loop:

>>> import operator
>>> max(map(lambda x:operator.pow(x, 2), [5, -7, 3]))
49
>>>

Thank you bvdet for your solution, you are almost there.
But, how can we return the original value which are -7?

>>> maxSquare([5, ‐7, 3])
-7

Do the same thing but instead of using the pow function, use an absolute value function.

It can be done using an additional variable, list method index() and the indexing operator.

>>> numList = 5, -7, 3
>>> sqList = map(lambda x:operator.pow(x, 2), numList)
>>> numList[sqList.index(max(sqList))], max(sqList)
(-7, 49)
>>>
