Python Alphabet Pattern 20

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(69, 64, -1):
        if(j <= i):
            a = chr(j)
            print(a, end="")
        else:
            print(" ", end="")
    print()

💻 Testing the Program

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

Output

    A
   BA
  CBA
 DCBA
EDCBA

🧠 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 the ASCII codes of the uppercase letters 'A' to 'E' in the English alphabet.
Within the outer loop, there is an inner loop (for j in range(69, 64, -1):) that iterates in reverse from 69 to 64 (inclusive) with a step of -1. These values represent the ASCII codes of the uppercase letters 'E' to 'A' in reverse order.
The inner loop checks if j is less than or equal to i. In the context of the program, i represents the current value of the outer loop and corresponds to the ASCII code of the letter to be printed in each row, while j represents the ASCII code of the letters to be printed in each column.
If the condition j <= i is satisfied, the program converts the ASCII code j to its corresponding character using a = chr(j) and then prints the character without moving to the next line (end="").
If the condition j <= i is not satisfied, the program prints a space character to create the desired pattern and alignment.
After each inner loop iteration, a print() statement is used to move to the next line, creating a new row in the 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.
