Code Explanation:

 Importing Necessary Libraries

import numpy as np

import matplotlib.pyplot as plt

numpy (np) → Used for selecting random colors (np.random.choice)

matplotlib.pyplot (plt) → Used for creating and displaying the plot

Setting Grid Size and Tile Size

rows, cols = 10, 10  

tile_size = 1  

Defines a 10×10 grid (rows = 10, cols = 10)

Each tile (square) has a side length of 1 unit

Creating the Figure & Axes

fig, ax = plt.subplots(figsize=(8, 8))

Creates a figure (fig) and an axis (ax)

figsize=(8, 8) → Creates an 8×8-inch plot

Setting Axis Limits

ax.set_xlim(0, cols * tile_size)

ax.set_ylim(0, rows * tile_size)

ax.set_xlim(0, cols * tile_size) → X-axis ranges from 0 to cols * tile_size = 10 * 1 = 10

ax.set_ylim(0, rows * tile_size) → Y-axis ranges from 0 to rows * tile_size = 10 * 1 = 10

This ensures the entire grid fits within the defined space

Maintaining Square Tiles and Hiding Axes

ax.set_aspect('equal')

ax.axis('off')

ax.set_aspect('equal') → Ensures the tiles are perfect squares

ax.axis('off') → Hides the axes (grid lines, ticks, labels) for a clean look

Defining Colors for the Tiles

colors = ['#6FA3EF', '#F4C542', '#E96A64', '#9C5E7F']

A list of 4 hex color codes

Colors used:

#6FA3EF (Light Blue)

#F4C542 (Yellow)

#E96A64 (Red-Orange)

#9C5E7F (Dark Purple)

The colors are chosen randomly for each tile

Creating the Mosaic Tiles Using Nested Loops

for row in range(rows):

    for col in range(cols):

Outer loop (row) → Iterates through each row

Inner loop (col) → Iterates through each column

This ensures we fill all (10 × 10) = 100 tiles in the mosaic grid

Setting Tile Position and Assigning Random Color

x = col * tile_size  

y = row * tile_size  

color = np.random.choice(colors)  

x = col * tile_size → Calculates X-coordinate of the tile

y = row * tile_size → Calculates Y-coordinate of the tile

np.random.choice(colors) → Randomly selects a color for the tile

Drawing the Tiles

square = plt.Rectangle((x, y), tile_size, tile_size, color=color, ec='white', lw=2)

ax.add_patch(square)

plt.Rectangle((x, y), tile_size, tile_size, color=color, ec='white', lw=2)

Creates a square tile at (x, y)

Size = tile_size × tile_size (1×1)

color=color → Assigns the random color

ec='white' → Adds a white border around each tile

lw=2 → Sets the border width to 2

ax.add_patch(square) → Adds the tile to the plot

Adding a Title

plt.title("Mosaic Tile Pattern", fontsize=16, fontweight='bold', color='navy', pad=15)

Adds a title "Mosaic Tile Pattern" to the plot

Title settings:

fontsize=16 → Large text

fontweight='bold' → Bold text

color='navy' → Dark blue text

pad=15 → Adds space above the title

Displaying the Pattern

plt.show()

Displays the final mosaic tile pattern
