Pyramid Pattern Plot using Python

 import matplotlib.pyplot as plt

rows = 5

plt.figure(figsize=(6, 6))

for i in range(rows):

    for j in range(2 * i + 1):  

        x = j - i  

        y = -i

        plt.scatter(x, y, s=500, c='gold')  

plt.xlim(-rows, rows)

plt.ylim(-rows, 1)

plt.axis('off')

plt.gca().set_aspect('equal', adjustable='datalim')

plt.title("Pyramid Pattern Plot", fontsize=14)

plt.show()

Code Explanation:

1. Import Required Library

import matplotlib.pyplot as plt

matplotlib.pyplot is used for plotting the pattern.

2. Define the Number of Rows

rows = 5

This sets the height of the pyramid (i.e., the number of rows).

3. Create the Figure

plt.figure(figsize=(6, 6))

Creates a 6x6 inch figure to display the plot properly.

4. Generate the Pyramid Pattern Using Nested Loops

for i in range(rows):  # Loop through each row

    for j in range(2 * i + 1):  # Increasing dots to form a pyramid

        x = j - i  # Centers the pyramid

        y = -i  # Moves rows downward

        plt.scatter(x, y, s=500, c='gold')  # Plot gold-colored dots

Outer loop (i) → Controls the number of rows.

Inner loop (j) → Controls the number of dots per row:

Row 0 → 1 dot

Row 1 → 3 dots

Row 2 → 5 dots

Row 3 → 7 dots

Row 4 → 9 dots

The pattern follows the formula:

Dots in row 

Dots in row i=2i+1

Plotting the dots:

plt.scatter(x, y, s=500, c='gold')

s=500 → Sets the dot size.

c='gold' → Colors the dots gold.

5. Adjust the Axis Limits

plt.xlim(-rows, rows)

plt.ylim(-rows, 1)

X-axis limit: (-rows, rows) → Ensures the pyramid is centered.

Y-axis limit: (-rows, 1) → Ensures the pyramid is properly positioned.

6. Format the Plot

plt.axis('off')  # Hides the x and y axes

plt.gca().set_aspect('equal', adjustable='datalim')  

plt.title("Pyramid Pattern Plot", fontsize=14)  

Removes the axis for a clean look.

Ensures equal spacing for uniform dot distribution.

Adds a title to the plot.

7. Display the Final Output

plt.show()

Displays the pyramid pattern.
