Get max value from a list with lists?

Question

So I have a list that contains several list which all have three strings first, then one float number, like:

resultlist = [[\"1\", \"1\", \"a\", 8.3931], [\         


        

Answer 1

In perhaps a more functional than pythonic manner:

>>> max(map(lambda x: x[3], resultlist))
9.1931

It begins by mapping each element of result list to the number value and then finds the max.

The intermediate array is:

>>> map(lambda x: x[3], resultlist)
[8.3931000000000004, 6.3231000000000002, 9.1930999999999994]
