Python Alphabet Pattern 30

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

example.py

Copied

init = 64;
for i in range(70, 65, -1):
    init += 1;
    for j in range(init, 65, -1):
        a = chr(j)
        print(a, end="")
    for k in range(65, i):
        a = chr(k)
        print(a, end="")
    print()

💻 Testing the Program

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

Output

ABCDE
BABCD
CBABC
DCBAB
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

init = 64: Initializes the variable init with the value 64.
for i in range(70, 65, -1):: This outer loop iterates through a range of values from 70 to 65 (exclusive) in reverse order (decreasing by 1). So, i takes the values 70, 69, 68, 67, and 66.
init += 1: Increments the value of init by 1 in each iteration of the outer loop.
for j in range(init, 65, -1):: This inner loop iterates through a range of values starting from the current value of init and going down to 65 (exclusive) in reverse order. It uses the variable j to represent these values.
a = chr(j): Converts the integer value j to its corresponding Unicode character using the chr() function and assigns it to the variable a.
print(a, end=""): Prints the character a without moving to a new line due to the end="" parameter.
for k in range(65, i):: This loop iterates through a range of values starting from 65 and ending at i - 1. It uses the variable k to represent these values. Since i varies in each iteration of the outer loop, the range of k values also changes.
a = chr(k): Similar to step 5, this converts the integer value k to its corresponding Unicode character and assigns it to the variable a.
print(a, end=""): Prints the character a without moving to a new line.
print(): Prints a newline character, moving the output to the next line. This is done after both inner loops have finished their iterations, creating a new line 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.
