Python Alphabet Pattern 19

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

example.py

Copied

for i in range(65, 70):
    for j in range(65, 70):
        if(j <= i):
            a = chr(j)
            print(a, end="")
        else:
            print(" ", end="")
    for k in range(69, 64, -1):
        if(k <= i):
            b = chr(k)
            print(b, end="")
        else:
            print(" ", end="")
    print()

💻 Testing the Program

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

Output

A        A
AB      BA  
ABC    CBA
ABCD  DCBA
ABCDEEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The outer loop for i in range(65, 70): iterates through the values from 65 to 69 (inclusive). These values represent ASCII codes of characters 'A' to 'E'.
Inside the outer loop, there are two nested loops that generate the characters for each row of the pyramid.
The first nested loop for j in range(65, 70): iterates through the values from 65 to 69 (inclusive) again. This loop is responsible for printing characters in ascending order on the left side of the pyramid.
Inside the first nested loop, there's an if condition if(j <= i): that checks if the current value j is less than or equal to the value of the outer loop variable i. If true, it converts the ASCII value j to a character using chr(j) and prints it without moving to a new line (end="" ensures no newline character is printed).
If the if condition is false (i.e., j is greater than i), it prints a space character using print(" ", end="").
After the first nested loop, there's a second nested loop for k in range(69, 64, -1): which iterates through the values from 69 to 64 (inclusive) in reverse order. This loop is responsible for printing characters in descending order on the right side of the pyramid.
Inside the second nested loop, there's an if condition if(k <= i): that checks if the current value k is less than or equal to the value of the outer loop variable i. If true, it converts the ASCII value k to a character using chr(k) and prints it without moving to a new line.
If the if condition is false (i.e., k is greater than i), it prints a space character using print(" ", end="").
Finally, after both nested loops have completed for a given value of i, a print() statement is used to move to the next line, creating the appearance of a new row in the pyramid.

💯 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.
