Python Pyramid Star Pattern Generator

Print aligned, centered pyramid structures using star characters in Python.

How it Works

Pattern printing is a fundamental exercise that trains developers in using loops, variables, and calculating string alignments.

A centered pyramid of height H consists of rows containing spaces and stars. Row `i` (0-indexed) requires `H - i - 1` leading spaces and `2*i + 1` stars.

We use Python's string multiplication capabilities to generate spaces and stars dynamically.

Source Code

Pyramid printing using nested string operations.

Try in Editor

def print_pyramid(height):
    for i in range(height):
        # Calculate spaces and stars
        spaces = " " * (height - i - 1)
        stars = "*" * (2 * i + 1)
        print(spaces + stars)

print("Pyramid of height 4:")
print_pyramid(4)

Terminal Output

Pyramid of height 4:
   *
  ***
 *****
*******

Frequently Asked Questions

How can I print an inverted pyramid?

Reverse the iteration: start the loop from `height - 1` and decrement down to `0`.
