Python Star Pattern 9

Here`s a program that prints the above star pattern using Python Programming:

example.py

Copied

for i in range(5, 0, -1):
    for j in range(0, 5):
        if(i == j):
           print("*",end="")
        else:
           print(" ",end="")
    for j in range(3, 0, -1):
        if(i == j):
           print("*",end="")
        else:
           print(" ",end="")
    print()

for i in range(0, 5):
    for j in range(0, 5):
        if(i == j):
           print("*",end="")
        else:
           print(" ",end="")
    for j in range(3, -1, -1):
        if(i == j):
           print("*",end="")
        else:
           print(" ",end="")
    print()

💻 Testing the Program

When you run the above program, it will print the following output:

🧠 How the Program Works

Let's break down the logic behind the code:

The program consists of two main loops, each responsible for generating one half of the diamond.
First Loop (Top Half):
- The outer loop runs from 5 down to 1 in reverse (using range(5, 0, -1)).
- The first set of nested loops (for j in range(0, 5)) is responsible for printing the spaces and stars before the central star in the current row. It checks if the current value of j is equal to the current value of i (outer loop variable), and if so, it prints a * character. Otherwise, it prints a space.
- The second set of nested loops (for j in range(3, 0, -1)) is responsible for printing the spaces and stars after the central star in the current row. It follows the same logic as the first set of loops.
- After each row is printed, a newline character is printed to move to the next line.
Second Loop (Bottom Half):
- The outer loop runs from 0 to 4 (using range(0, 5)).
- The first set of nested loops (for j in range(0, 5)) is responsible for printing the spaces and stars before the central star in the current row. It follows the same logic as in the top half.
- The second set of nested loops (for j in range(3, -1, -1)) is responsible for printing the spaces and stars after the central star in the current row. It follows the same logic as in the top half.
- After each row is printed, a newline character is printed to move to the next line.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
