🚀 Day 28/150 – Print Odd Numbers up to N in Python

Printing odd numbers up to N is a simple and useful exercise to practice loops, conditions, and number logic in Python.

👉 An odd number is any number that is not divisible by 2.

Examples: 1, 3, 5, 7, 9...

Let’s explore different methods 👇

🔹 Method 1 – Using for Loop

The easiest and most efficient way.

n = 10

for i in range(1, n + 1, 2):
    print(i)

✅ Explanation:

• Starts from 1
• Increments by 2
• Prints only odd numbers

🔹 Method 2 – Using Condition inside Loop

Check each number manually.

n = 10

for i in range(1, n + 1):
    if i % 2 != 0:
        print(i)

✅ Explanation:

• % 2 != 0 checks if the number is odd
• Prints only numbers that satisfy the condition

🔹 Method 3 – Taking User Input

Make the program dynamic.

n = int(input("Enter a number: "))

for i in range(1, n + 1, 2):
    print(i)

🔹 Method 4 – Using while Loop

Condition-based approach.

n = 10
i = 1

while i <= n:
    print(i)
    i += 2

✅ Explanation:

• Starts from 1
• Runs until i <= n
• Increases by 2

 Final Thoughts

• Best method: range(1, n+1, 2) 
• Condition method improves logic building 
• while loop gives more control
