🚀 Day 10/150 – Find the Largest of Two Numbers in Python

Welcome back to the 150 Days of Python series!
Today, we’ll solve a very common problem: finding the largest of two numbers.

This is a fundamental concept that helps you understand conditions, functions, and Python shortcuts.

🎯 Problem Statement

Write a Python program to find the largest of two numbers.

✅ Method 1 – Using if-else

The most basic and beginner-friendly approach.

a = 10
b = 25

if a > b:
    print("Largest number is:", a)
else:
    print("Largest number is:", b)

👉 Explanation:
We simply compare both numbers and print the greater one.

✅ Method 2 – Taking User Input

Make your program interactive.

a = float(input("Enter first number: "))
b = float(input("Enter second number: "))

if a > b:
    print("Largest number is:", a)
else:
    print("Largest number is:", b)

👉 Why this matters:
Real-world programs always take input from users.

✅ Method 3 – Using a Function

Reusable and cleaner approach.

def find_largest(x, y):
    if x > y:
        return x
    else:
        return y

print("Largest number:", find_largest(10, 25))

👉 Pro Tip:
Functions help you reuse logic anywhere in your code.

✅ Method 4 – Using Built-in max() Function

The easiest and most Pythonic way.

a = 10 b = 25 print("Largest number:", max(a, b))

👉 Why use this?

Python already provides optimized built-in functions — use them!.

✅ Method 5 – Using Ternary Operator (One-Liner)

Short and elegant.

a = 10
b = 25

largest = a if a > b else b
print("Largest number is:", largest)

👉 Best for:

Writing clean and compact code.

🧠 Summary

Method	Best For
if-else	Beginners
User Input	Real-world programs
Function	Reusability
max()	Clean & Pythonic
Ternary	Short one-liners

💡 Final Thoughts

There are multiple ways to solve the same problem in Python 
and that’s what makes it powerful!

👉 Start simple → then move to cleaner and optimized approaches.
