Python Number Pattern 21

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

example.py

Copied

for i in range(1, 6):
    print(i, end=" ")
    m = 4;
    k = i + m
    for j in range(1, i):
        print(k, end=" ")
        m -= 1;
        k = k + m;
    print()

💻 Testing the Program

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

Output

1
2 6
3 7 10
4 8 11 13 
5 9 12 14 15

🧠 How the Program Works

Let's break down the logic behind the code:

The outer loop: for i in range(1, 6):
- This loop iterates from 1 to 5 (inclusive). The loop variable i takes values from 1 to 5 in each iteration.
Inside the outer loop, we have the following lines:
- print(i, end=" "): This prints the value of i followed by a space, without moving to a new line.
- m = 4: Initializes a variable m with the value 4.
k = i + m: Computes the value of k as the sum of i and m. This value is used in the inner loop.
The inner loop: for j in range(1, i):
- This loop iterates from 1 to i-1, where i is the current value from the outer loop. It runs i - 1 times for each iteration of the outer loop.
Inside the inner loop, we have the following lines:
- print(k, end=" "): Prints the value of k followed by a space, without moving to a new line.
- m -= 1: Decrements the value of m by 1.
- k = k + m: Updates the value of k by adding the new value of m.
After the inner loop, we have print(): This prints a newline character, moving the output 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.
