Day 3: Subtract two numbers in Python

 

🚀 Day 3/150 – Subtract Two Numbers in Python

1️⃣ Basic Subtraction (Direct Method)

The simplest way to subtract two numbers is by using the - operator.

a = 10 b = 5 result = a - b print(result)

Output

5

This method directly subtracts b from a and stores the result in a variable.

2️⃣ Taking User Input

In real programs, numbers often come from user input rather than being predefined.

a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print("Difference:", a - b)

Hegers.

Here we use input() to take values from the user and int() to convert them into integers.

3️⃣ Using a Function

Functions help make code reusable and organized.

def subtract(x, y): return x - y print(subtract(10, 5))

The function subtract() takes two parameters and returns their difference.

4️⃣ Using a Lambda Function (One-Line Function)

A lambda function is a small anonymous function written in a single line.

subtract = lambda x, y: x - y print(subtract(10, 5))

Lambda functions are useful when you need a short, temporary function.

5️⃣ Using the operator Module

Python also provides built-in modules that perform mathematical operations.

import operator print(operator.sub(10, 5))

The operator.sub() function performs the same subtraction operation.

6️⃣ Using List and reduce()

Another approach is to store numbers in a list and apply a reduction operation.

from functools import reduce numbers = [10, 5] result = reduce(lambda x, y: x - y, numbers) print(result)



















reduce() applies the function cumulatively to the items in the list.

🎯 Conclusion

There are many ways to subtract numbers in Python. The most common method is using the - operator, but functions, lambda expressions, and built-in modules provide more flexibility in larger programs.

In this series, we explore multiple approaches so you can understand Python more deeply and write better code.
