Python's core library has two built-in functions max() and min() respectively to find maximum and minimum number from a sequence of numbers in the form of list or tuple object.
example
>>> max(23,21,45,43) 45 >>> l1=[20,50,40,30] >>> max(l1) 50 >>> t1=(30,50,20,40) >>> max(t1) 50 >>> min(l1) 20 >>> min(t1) 20 >>> min(23,21,45,43) 21
