Python Alphabet Pattern 21

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

example.py

Copied

for i in range(65, 70):
    count = 1
    for j in range(64, i):
        a = chr(i)
        if(count == 1):
            print(a, end="")
            count = 2
        else:
            print("*"+a, end="")
    print()

for i in range(68, 64, -1):
    count = 1
    for j in range(64, i):
        if(count == 1):
            a = chr(i)
            print(a, end="")
            count = 2
        else:
            print("*"+a, end="")
    print()

💻 Testing the Program

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

Output

A
B*B
C*C*C
D*D*D*D
E*E*E*E*E
D*D*D*D
C*C*C
B*B
A

🧠 How the Program Works

Let's break down the logic behind the code:

First Loop (i in range(65, 70)):
- The outer loop iterates over the values of i from 65 to 69 (inclusive).
- Inside this loop, a variable count is initialized to 1 for each iteration.
First Inner Loop (j in range(64, i)):
- An inner loop iterates over the values of j from 64 to i - 1.
- Inside this loop, a character a is assigned the Unicode character represented by the value of i (which corresponds to the ASCII code of the current value of i).
- If count is 1, it prints the character a without any asterisk, and then sets count to 2.
- If count is not 1 (i.e., it's 2), it prints an asterisk followed by the character a.
Print newline:
- After each iteration of the inner loop, a newline is printed to move to the next line.
Second Loop (i in range(68, 64, -1)):
- The outer loop iterates over the values of i from 68 to 65 (inclusive) in reverse order.
- Inside this loop, a variable count is initialized to 1 for each iteration.
Second Inner Loop (j in range(64, i)):
- An inner loop iterates over the values of j from 64 to i - 1.
- Inside this loop, a character a is assigned the Unicode character represented by the value of i.
- If count is 1, it prints the character a without any asterisk, and then sets count to 2.
- If count is not 1 (i.e., it's 2), it prints an asterisk followed by the character a.
Print newline:
- After each iteration of the inner loop, a newline is printed to move to the next line.

💯 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.
