Python Alphabet Pattern 18

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

example.py

Copied

for i in range(1, 6):
    for j in range(65, 65+i):
        a = chr(j)
        print(a, end="")
    for k in range(63+i, 64, -1):
        a = chr(k)
        print(a, end="")
    print()

💻 Testing the Program

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

Output

A
ABA
ABCBA
ABCDCBA
ABCDEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The outer loop for i in range(1, 6): runs for values of i from 1 to 5 (inclusive). This loop controls the number of rows in the pattern.
Inside the outer loop, there are two nested loops:
1. The first nested loop for j in range(65, 65+i): runs for values of j starting from the ASCII value 65 (which corresponds to the character 'A') and goes up to 65 + i - 1. This loop generates and prints characters from 'A' to 'A' + i - 1.
2. The second nested loop for k in range(63+i, 64, -1): runs for values of k starting from 63 + i and decrements by 1 until it reaches 64. This loop generates and prints characters from the ASCII value of 'A' + i - 1 down to 'A' + 1.
Inside each of the nested loops, the program does the following:
1. a = chr(j): Converts the ASCII value j to its corresponding character using the chr() function and assigns it to the variable a.
2. print(a, end=""): Prints the character a without moving to the next line.
After both nested loops have executed, the program prints a newline character using print() to move to the next row for the next iteration of the outer loop.

💯 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.
