FUNCTION PROGRAMS IN PYTHON

EXAMPLE 01: ADD TWO NUMBERS

>>> def add(x,y):
        return(x+y)
    
>>> a = 3
>>> b = 5
>>> c = add(a,b)
>>> print ( "sum of ",a," & ",b," is ",c)
 
Output:
sum of 3 & 5 is 8

>>> def add(x,y):
        return(x+y)
>>> a = int(input ("enter first number "))
>>> b = int(input ("enter second number "))
>>> c = add(a,b)
>>> print ( "sum of ",a," & ",b," is ",c)
 
Output:
enter first number 5
enter second number 6
sum of  5  &  6  is  11

EXAMPLE 02: AREA OF RECTANGLE

>>> def area(l,b):
        return(l*b)
    
>>> l = int(input ("enter length "))
>>> b = int(input ("enter breadth "))
>>> a = area(l,b)
>>> print("area of rectangle is ",a)
 
Output:
enter length 5
enter breadth 6
area of rectangle is  30

EXAMPLE 03: ODD OR EVEN NUMBER

>>> def oe(num):
        if (num%2==0):
            print(num," is even number")
        else:
            print(num," is odd number")
            
>>> num = int(input ("enter a number : "))
>>> oe(num)
 
Output:
enter a number : 4
4  is even number

EXAMPLE 04: CHECK PRIME NUMBER

>>> def prime(a):
        c = 0
        if (a<1):
            print("invalid input ! Try next number ")
        elif(a==1):
            print ("1 is not prime")
        else:
            for i in range(2,a,1):
                if (a%i==0):
                    c=1
            if (c==0):
                print(a," is prime")
            else:
                print(a," is not prime")
                
>>> num = int (input("enter a number : "))
>>> prime(num)
 
Output:
enter a number: 6
6  is not prime

EXAMPLE 05: AREA OF RECTANGLE USING LAMBDA

#>>> area = (lambda x,y : x*y)(5 , 4)     next method
>>> area = (lambda x,y : x*y)
>>> print ( area(5,4))
 
Output:
Area of rectangle is : 20
