Python Program to Find Largest Among Three Numbers

Python Program to Find Largest Among Three Numbers. Determining the largest number among the given three numbers is a basic yet essential task in programming, especially when beginning to understand conditional structures in Python. This article will guide you through writing Python programs that efficiently find the largest number among three numbers using simple comparison techniques.

Using if-else Condition

The most straightforward approach to finding the largest number among three numbers is by using a series of if-else statements to compare the numbers directly. This method is very easy to understand for beginners.

def find_largest(a,b,c):
    if a>=b and a>=c:
        return a
    elif b>=a and b>=c:
        return b
    else:
        return c
num1 = 345
num2 = 256
num3 = 989
largest = find_largest(num1,num2,num3)    
print(largest)

Using the ‘max()’ Function

Python’s built-in 'max()'function provides a highly efficient and concise way to determine the largest number. This function can take multiple arguments and return the largest one, making your code cleaner.

num1 = 575
num2 = 956
num3 = 439
largest = max(num1,num2,num3)    
print(largest)

Using ternary Operator

For those who prefer a more compact form, the ternary operator in Python offers a way to reduce the lines of code while still maintaining clarity. This method is suitable for more experienced programmers familiar with Python’s concise syntax.

def find_largest(a,b,c):
    return a if a>b and b>c else (b if b>c else c)
num1 = 1245
num2 = 2256
num3 = 9989
largest = find_largest(num1,num2,num3)    
print(largest)

Finding the largest number of three in Python can be achieved through multiple approaches, each with its own advantages. whether you prefer straightforward conditional statements or the concise power of Python’s built-in functions.
