Print a Left-Aligned Star Triangle Based on n in Python

Program Overview

This Python program reads an integer n between 1 and 80 and prints a left-aligned triangle of asterisks (*) with n rows.
Each row contains one more asterisk than the previous, forming a simple triangular pattern aligned to the left.

Python Code:

# Read n from user
n = int(input("Enter a number between 1 and 80: "))

# Validate input
if 1 <= n <= 80:
    for i in range(1, n + 1):
        print('*' * i)
else:
    print("The number must be between 1 and 80.")

Sample Output for n = 7:

*
**
***
****
*****
******
*******

Step-by-Step Explanation:

- The user inputs a number n
- The program checks that n is within the valid range
- A loop runs from 1 to n
- In each iteration, i asterisks are printed on the same line
- The result is a left-aligned triangle of height n
