Python Alphabet Pattern 29

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

example.py

Copied

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

    for j in range(65, k):
        if(j > i):
            b = chr(j)
        else:
            b = chr(i)
        print(b, end=" ")
    print()

for i in range(66, k):
    for j in range(k-1, 65, -1):
        if(j > i):
            a = chr(j)
        else:
            a = chr(i)
        print(a, end=" ")
    for j in range(65, k):
        if(j > i):
            b = chr(j)
        else:
            b = chr(i)
        print(b, end=" ")
    print()

💻 Testing the Program

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

Output

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

🧠 How the Program Works

Let's break down the logic behind the code:

k = 70: This line initializes a variable k with the value 70.
The program enters the first outer loop using for i in range(69, 64, -1):.
- This loop iterates from 69 to 64 (inclusive) in reverse order, with i taking on each value in that range.
Inside the first outer loop, there are two nested loops.
- The first inner loop, for j in range(k-1, 65, -1):, iterates from k-1 down to 65 (inclusive) in reverse order, with j taking on each value in that range.
  - If j > i, it sets a to the character represented by the Unicode value j.
  - Otherwise, it sets a to the character represented by the Unicode value i.
  - Then, it prints the character a followed by a space, using end=" " to prevent a newline.
- The second inner loop, for j in range(65, k):, iterates from 65 up to k-1 (inclusive), with j taking on each value in that range.
  - If j > i, it sets b to the character represented by the Unicode value j.
  - Otherwise, it sets b to the character represented by the Unicode value i.
  - Then, it prints the character b followed by a space.
After both inner loops finish, a print() statement is used to move to the next line, creating a newline in the output.
The second outer loop starts with for i in range(66, k):.
- This loop iterates from 66 to 69 (inclusive) with i taking on each value in that range.
Inside the second outer loop, there are again two nested loops, similar to what was done in the first outer loop.
The loops within the second outer loop perform similar actions as explained in steps 3 and 4.
Once both outer loops and their respective inner loops finish executing, the entire pattern is printed.

💯 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.
