4 lambdas solution in Clear category for Min and Max by roman.bratishchev
from functools import reduce
from operator import ge,le
max,min=map(lambda op:lambda *args,key=None:reduce(lambda a,b,key=(key,lambda x:x)[key==None]:(b,a)[op(key(a),key(b))], (args[0],args)[len(args)>1]), (ge,le))
if __name__ == "__main__":
# These "asserts" using only for self-checking and not necessary for auto-testing
assert max(3, 2) == 3, "Simple case max"
assert min(3, 2) == 2, "Simple case min"
assert max([1, 2, 0, 3, 4]) == 4, "From a list"
assert min("hello") == "e", "From string"
assert max(2.2, 5.6, 5.9, key=int) == 5.6, "Two maximal items"
assert min([[1, 2], [3, 4], [9, 0]], key=lambda x: x[1]) == [9, 0], "lambda key"
