In this tutorial, we will discuss Python program to add two number using function
In this topic, we will learn a simple concept of how to add two numbers using the function in the Python programming language
already we learned the same this concept using the operator in a simple way.
Program 1
Add two integer number using the function
1 2 3 4 5 6 7 8 9 10 11 | #Python program to add two numbers using function def add_num(a,b):#function for addition sum=a+b; return sum; #return value num1=25 #variable declaration num2=55 print("The sum is",add_num(num1,num2))#call the function |
When the above code is compiled and executed, it produces the following results
1 2 3 | The sum is 80 |
Add two integer number using the function – get input from the user
Program 2
1 2 3 4 5 6 7 8 9 10 11 | #Python program to add two numbers using function def add_num(a,b):#function for addition sum=a+b; return sum; #return value num1=int(input("input the number one: "))#input from user for num1 num2=int(input("input the number one :"))#input from user for num2 print("The sum is",add_num(num1,num2))#call te function |
When the above code is compiled and executed, it produces the following results
1 2 3 4 5 | input the number one: 34 input the number one: 45 The sum is 79 |
This is the program asked input from user two numbers and displays the sum of two numbers entered by the user
We can use pre-defined python function input() to takes input from the user. Input() function returns a string value. So we can use int() function to convert from string to int data type (shown in line 6 and 7).
Add two floating point number using the function
Program 3
1 2 3 4 5 6 7 8 9 10 11 | #Python program to add two numbers using function def add_num(a,b):#function for addition sum=a+b; return sum; #return value num1=2.456 #variable declaration num2=55.54 print("The sum is",add_num(num1,num2))#call te function |
1 2 3 | the sum is 57.996 |
Add two float numbers using the function – get input from the user
1 2 3 4 5 6 7 8 9 10 11 | #Python program to add two numbers using function def add_num(a,b):#function for addition sum=a+b; return sum; #return value num1=float(input("input the number one: "))#input from user for num1 num2=float(input("input the number one: "))#input from user for num2 print("The sum is",add_num(num1,num2))#call te function |
1 2 3 4 5 | input the number one: 34.4 input the number one: 32.45 The sum is 66.85 |
This is the program asked input from user two numbers and displays the sum of two numbers entered by the user
We can use pre-defined python function input() to takes input from the user. Input() function returns a string value. So we can use float() function to convert from string to float data type (shown in line 6 and 7).
