Python Number Pattern 28

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

example.py

Copied

for i in range(10, 0, -1):
    for j in range(i, 10):
           print(j, end="")
    print("0", end="")
    for k in range(9, i-1, -1):
           print(k, end="")
    print()

💻 Testing the Program

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

Output

0
909
89098
7890987
678909876
56789098765
4567890987654
345678909876543
23456789098765432
1234567890987654321

🧠 How the Program Works

Let's break down the logic behind the code:

The outer loop for i in range(10, 0, -1): iterates from 10 down to 1 in reverse order. This loop controls the number of rows printed in the output pattern.
Inside the outer loop, there's a nested loop for j in range(i, 10):. This loop iterates from the current value of i to 9. The purpose of this loop is to print the first sequence of numbers that increment from i to 9.
Within the nested loop, print(j, end="") is used to print the value of j without moving to the next line.
After the nested loop, print("0", end="") is used to print a single 0.
The next nested loop is for k in range(9, i-1, -1):. This loop iterates from 9 down to the value of i (inclusive), in reverse order. This loop is responsible for printing the second sequence of numbers that decrement from 9 to the value of i.
Similar to the first nested loop, print(k, end="") is used to print the value of k without moving to the next line.
Finally, after both nested loops, print() is used to print a newline character, moving to the next 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.
