🚀 Day 26/150 – Print Numbers from 1 to N in Python

Printing numbers from 1 to N is one of the most basic and important programming exercises. It helps you understand loops, iteration, and how Python executes repeated tasks.

Let’s explore different ways to achieve this 👇

🔹 Method 1 – Using for Loop

The most common and beginner-friendly approach.

n = 10

for i in range(1, n + 1):
    print(i)

✅ Explanation:

• range(1, n + 1) generates numbers from 1 to N
• The loop prints each number one by one

🔹 Method 2 – Taking User Input

Make the program dynamic by taking input from the user.

n = int(input("Enter a number: ")) for i in range(1, n + 1): print(i)

 


✅ Explanation

input() takes value from the user

int() converts it into an integer

Loop prints numbers accordingly

🔹 Method 3 – Using while Loop

A condition-based approach.

n = 10
i = 1

while i <= n:
    print(i)
    i += 1

✅ Explanation:

• Starts from i = 1
• Runs until i <= n
• Increments i after each iteration

🔹 Method 4 – Using List Comprehension

A more compact and Pythonic way.

n = 10

numbers = [i for i in range(1, n + 1)]
print(numbers)

✅ Explanation:

• Creates a list of numbers from 1 to N
• Prints all values at once

🎯 Final Thoughts

• Use for loop for simple iteration ✅
• Use while loop when working with conditions 🔄
• Use list comprehension for compact code 🧠
