Python Alphabet Pattern 23

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

example.py

Copied

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

💻 Testing the Program

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

Output

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

🧠 How the Program Works

Let's break down the logic behind the code:

The outer loop for i in range(69, 64, -1): iterates over a range of numbers from 69 down to 64 (both inclusive) in steps of -1. This loop controls the number of rows in the pattern.
Inside the outer loop, k = 70 initializes a variable k with the value 70. This variable is used to generate characters from 'A' to a certain letter.
The inner loop for j in range(65, 70): iterates over a range of numbers from 65 to 69 (inclusive). This loop controls the number of columns in each row.
The if j >= i: condition checks if the current value of j (representing the current column) is greater than or equal to the current value of i (representing the current row). This condition determines whether a character should be printed or not.
If the condition is met, k is decremented by 1 (k -= 1), and then the character corresponding to the current value of k is obtained using a = chr(k).
If the condition is not met (i.e., the current column is before the diagonal), a space character is printed.
After either printing a character or a space for each column, print(" ", end=" ") or print(a, end=" ") is used to display the character (or space) without moving to the next line.
The print() statement without any arguments is used to move to the next line, completing the current row.
The process continues for each row, generating the desired 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.
