FACTORIAL OF A GIVEN NUMBER

def factorial(n):

    if n == 0:

        return 1

    else:

        return n * factorial(n-1)

n=int(input("Input a number to compute the factiorial : "))

print(factorial(n))

 

LARGEST NUMBER IN A LIST

def large(arr):

    maximum = arr[0]

    for ele in arr:

        if(ele > maximum):

           maximum= ele

    return maximum

 

list1 = []

n=int(input("enter the number of elements"))

    list1.append(n1)

 

for i in range(0,n):

         print(list1[i])

result = large(list1)

print("largest number",result)

AREA OF SHAPE

    area=l*l

    return area

 

 

def rectangle(l,w):

    area=l*w

    return area

 

    print("Please enter a number to calculate the area of shape")
