Python program to find largest number among three numbers

Python program to find largest number among three numbers

In this tutorial, we will discuss the Python program to find largest number among three numbers.

This post explains how to find the largest number among three numbers using if statements with the operator in Python.

There are many ways to find the largest number among the three numbers in Python. but here,  we use if elif statements and with the and operator.

Here, we provide two programs to find the largest number among the three numbers.

first program leads to find the largest number among three integer numbers.

Second program leads to find the largest number among three floating point numbers.

Find the largest number among three integer numbers

Program 1

num1=int(input("Enter the first number: "))
num2=int(input("Enter second number: "))
num3=int(input("Enter the third number: "))
#get input from user for num1,num2,num3

if(num1>num2) and (num1>num3):
    biggest=num1;
#check whether the num1 is smaller than num2 and num3

elif (num2>num1) and (num2>num3):
    biggest=num2;
#check whether the num2 is smaller than num1 and num3

else:
    biggest=num3;

print("The largest number is",biggest);

When the above code is executed, it produces the following results

Enter the first number: 98
Enter second number: 65
Enter the third number: 43
The largest number is 98

This program takes input from the user for num1,num2, num3. then, this program finds and displays the largest number among the three integer numbers

Find the largest number among three floating point numbers

Program 2

num1=float(input("Enter the first number: "))
num2=float(input("Enter second number: "))
num3=float(input("Enter the third number: "))
#get input from user for num1,num2,num3

if(num1>num2) and (num1>num3):
    biggest=num1;
#check whether num1 is smaller than num2 and num3

elif (num2>num1) and (num2>num3):
    biggest=num2;
#check whether the num2 is smaller than num1 and num3

else:
    biggest=num3;

print("The largest number is",biggest);

When the above code is executed, it produces the following results

Enter the first number: 23.65
Enter second number: 78.45
Enter the third number: 67.34
The largest number is 78.45

This program takes input from the user for num1,num2, num3. then, this program finds and displays the largest number among the three decimal numbers
