Computer: Ch.7 Function in Python (Notebook work)

Practical 1: Function Program in Python :

 def sum1(a1,a2):

    print("Addition : ",a1+a2)

def min1(a1,a2):

    print("Substruction : ",a1-a2)

def multi1(a1,a2):

    print("Multiplication : ",a1*a2)

while True:

    print('''

            [1]. Addition

            [2]. Substruction

            [3].Multiplication

            [0]. Exit''')

    ch=int(input("Enter any number :"))

    if ch==1:

        n1=int(input("Enter 1st Number : "))

        n2=int(input("Enter 2nd Number : "))

        sum1(n1,n2)

    elif ch==2:

        n1=int(input("Enter 1st Number : "))

        n2=int(input("Enter 2nd Number : "))

        min1(n1,n2)

    elif ch==3:

        n1=int(input("Enter 1st Number : "))

        n2=int(input("Enter 2nd Number : "))

        multi1(n1,n2)

    elif ch==0:

       print("Thank you....!!!!")

       break

    else:

        print("Select proper number....")
