Program of Average of two Numbers in Python

Average means arithmetic mean which can be calculated by the following formula

Average = Sum of all numbers/ Total numbers

for example: if we have to calculate the average of 3 and 7, so average of these numbers can be calculated as follows:

average = (3 + 7)/2

average = 5.0

Since the total numbers are two so we divided the sum of all the numbers by 2.

for example: if we have to calculate the average of 3, 6 and 9, so average of these numbers can be calculated as follows:

average = (3+6+9)/3

average = 6.0

Since the total numbers are three so we divided the sum of all the numbers by 3.

Suppose we have to calculate the average of 5, 10, 20, 15 and 10, so average of these numbers can be calculated as follows:

average = (5 + 10 + 20 + 15 + 10)/5

average = 12.0

Since the total numbers are five so we divided the sum of all the numbers by five.

Let we do the python program

Write a program in python to calculate the average of two numbers (integers).

num1 = int(input("Enter first number : ")) #Accepting first integer from user
num2 = int(input("Enter second number : "))#Accepting second integer from user
avrg = (num1 + num2)/2 #Calculating average 
print("Average of two numbers is : ", avrg)#Displaying the average

Line by Line explanation of above code

1. First line of code is for accepting a number(integer) from the user.
2. Second line of code is for accepting another number(integer) from the user.
3. In third line, we are calculating the average by adding both numbers and divided by 2. Result of average is stored in a variable “avrg” (You can take any other variable name)
4. Fourth Line is simply printing the result.

OUTPUT

Similarly we can also calculate the average of two floating point numbers

num1 = float(input("Enter first number : ")) #Accepting first from user
num2 = float(input("Enter second number : "))#Accepting second from user
avrg = (num1 + num2)/2 #Calculating average 
print("Average of two numbers is : ", avrg)#Displaying the average

OUTPUT

NOTE: We can accept either integer or floating numbers from user

Write a program in python to calculate the average of three numbers.

num1 = int(input("Enter first number : ")) #Accepting first integer from user
num2 = int(input("Enter second number : "))#Accepting second integer from user
num3 = int(input("Enter third number : "))
avrg = (num1 + num2 + num3)/3 #Calculating average
print("Average of three numbers is : ", avrg)#Displaying the average

OUTPUT

Average of two numbers in Python
