Pascal Triangle Generator with Python

Level: Beginner

Your task for today is to build a Pascal's Triangle Generator using nested loops. This challenge helps you understand loop structures and build mathematical patterns — a great way to practice nested iteration with a meaningful output.

📝 Project Task

The program should:

• Ask the user for the number of rows (e.g., 5).

• Use nested loops to calculate and print Pascal’s Triangle.

• Align the output to form a symmetrical triangle.

Bonus (optional):

• Format numbers with spacing to form a clean pyramid.

• Allow the user to export the triangle to a .txt file.

Pascal’s Triangle is a great example of how to use nested loops to compute values based on previous rows — a useful concept in both programming and mathematics.

📌 Expected Output

For 5 rows:

    1
   1 1
  1 2 1
 1 3 3 1
1 4 6 4 1
