I can do max(s) to find the max of a sequence. But suppose I want to compute max according to my own function, something like:
currmax = 0
def mymax(s):
for i in s :
#assume arity() attribute is present
currmax = i.arity() if i.arity() > currmax else currmax
Is there a clean pythonic way of doing this?

Use max() to Find Max Value in a List of Strings and Dictionaries. The function max() also provides support for a list of strings and dictionary data types in Python. The function max() will return the largest element, ordered by alphabet, for a list of strings. The letter Z is the largest value, and A is the smallest.
In Python, there is a built-in function max() you can use to find the largest number in a list. To use it, call the max() on a list of numbers. It then returns the greatest number in that list.
Use Python's min() and max() to find smallest and largest values in your data. Call min() and max() with a single iterable or with any number of regular arguments. Use min() and max() with strings and dictionaries.
max(s, key=operator.methodcaller('arity'))
or
max(s, key=lambda x: x.arity())
