Several example codes

Program Overview

This Python program uses nested loops to generate a number pattern.
Each row prints the numbers from 1 up to the row number.
This structure is a good exercise for learning nested loops.

Python Code:

# Read the number of rows from the user
n = int(input("Enter the number of rows: "))

# Build the pattern with nested loops
for i in range(1, n + 1):
    for j in range(1, i + 1):
        print(j, end=" ")
    print()

Sample Output:

Enter the number of rows: 5  

1  
1 2  
1 2 3  
1 2 3 4  
1 2 3 4 5

Step-by-Step Explanation:

- The outer loop controls the number of rows
- The inner loop prints the numbers from 1 up to the current row
- end=" " keeps the numbers on the same line
- print() moves to a new line after each row
