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

Loop through your outer list and select the last element of each sublist:

def max_value(inputlist):
    return max([sublist[-1] for sublist in inputlist])

print max_value(resultlist)
# 9.1931

It's also best if you keep all function related variables in-scope (pass the list as an argument and don't confuse the namespace by reusing variable names).
