Python Alphabet Pattern 4

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

example.py

Copied

for i in range(0, 5):
    for j in range(65 + i, 64, -1):
        a = chr(j)
        print(a, 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(0, 5): iterates through the numbers from 0 to 4. This loop controls the number of rows in the pattern.
The inner loop for j in range(65 + i, 64, -1): iterates through a range of ASCII values. The starting value of the range is 65 + i, where 65 represents the ASCII value of the letter 'A'. As i increases, the starting value also increases, causing the characters to shift one step to the right in each row. The end value of the range is 64, and the loop iterates in reverse using -1 as the step, so it decrements the ASCII value in each iteration.
Inside the inner loop, a = chr(j) converts the current ASCII value j to its corresponding character using the chr() function.
print(a, end="") prints the character a without moving to the next line due to the end="" argument. This effectively prints the characters in the same line.
After the inner loop completes, print() is used to print a newline character, moving to the next line for the next row.

💯 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.
