Python Alphabet Pattern 15

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

example.py

Copied

for i in range(5, 0, -1):
    for j in range(65, 65+i):
        a = chr(j)
        print(a, end="")
    for k in range(5, i, -1):
        print("*", end="")
    for m in range(5, i, -1):
        print("*", end="")
    for n in range(64+i, 64, -1):
        b = chr(n)
        print(b, end="")
    print()

💻 Testing the Program

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

Output

ABCDEEDCBA
ABCD**DCBA
ABC****CBA
AB******BA
A********A

🧠 How the Program Works

Let's break down the logic behind the code:

The outer loop iterates through the values of i from 5 to 1 in reverse order (due to the step of -1).
Inside the outer loop, there are four nested loops and a print() statement, responsible for printing the characters in the desired pattern for each iteration of the outer loop.
The first nested loop (for j in range(65, 65+i):) is responsible for printing a sequence of uppercase letters starting from ASCII value 65 ('A') up to 65 + i - 1. The variable a holds the character obtained using chr(j), and each character is printed on the same line.
The second nested loop (for k in range(5, i, -1):) prints asterisks (*) a certain number of times, based on the value of i. This loop prints 5 - i asterisks.
The third nested loop (for m in range(5, i, -1):) is essentially the same as the second nested loop, printing another set of asterisks.
The fourth nested loop (for n in range(64+i, 64, -1):) prints a sequence of uppercase letters starting from ASCII value 64 + i down to ASCII value 65 ('A') in reverse order. The variable b holds the character obtained using chr(n).
After all the nested loops are executed, a print() statement is used to move to the next line, creating a new line for the next iteration of the outer loop.
The process continues for each iteration of the outer loop, generating the desired pattern.

💯 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.
