Write a Python program that asks the user for a number n and calculates the sum of all numbers from 1 to n using a while loop.

 n = int(input("Enter a number: "))

sum_numbers = 0

i = 1

while i <= n:

    sum_numbers += i

    i += 1

print(f"The sum of numbers from 1 to {n} is {sum_numbers}")

Code Explanation:

Take User Input:

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

The program asks the user to enter a number n and converts it to an integer.

Initialize Variables:

sum_numbers = 0

i = 1

sum_numbers will store the total sum.

i is the counter variable, starting from 1.

Use a while Loop to Calculate the Sum:

while i <= n:

    sum_numbers += i

    i += 1

The loop runs as long as i is less than or equal to n.

In each iteration, i is added to sum_numbers, and i is incremented.

Print the Final Sum:

print(f"The sum of numbers from 1 to {n} is {sum_numbers}")

Displays the total sum.
