Python Star Pattern 10

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

example.py

Copied

for i in range(5, 0, -1):
    for j in range(i, 1, -1):
        print(" ",end="")
    for k in range(i, 6):
        print("*",end="")
    for m in range(i, 5, 1):
        print("*",end="")
    print()
		
for i in range(4, 0, -1):
    for j in range(i, 5, 1):
        print(" ",end="")
    for k in range(0, i):
        print("*",end="")
    for m in range(1, i):
        print("*",end="")
    print()

💻 Testing the Program

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

Output

     *
    ***
   *****
  *******
 *********
  *******
   *****
    ***
     *

🧠 How the Program Works

Let's break down the logic behind the code:

This part of the code creates the upper half of the pyramid:
1. The outer loop iterates from 5 to 1 (inclusive) in reverse order using the range(5, 0, -1) construct.
2. The first inner loop (for j in range(i, 1, -1):) prints spaces before the first set of stars. The number of spaces decreases by 1 in each iteration as j counts down from the current value of i to 2 (excluding 1).
3. The second inner loop (for k in range(i, 6):) prints the first set of stars. It starts from the current value of i and goes up to 5 (inclusive), printing stars to form the left half of each row.
4. The third inner loop (for m in range(i, 5, 1):) prints the second set of stars. It starts from the current value of i and goes up to 4 (inclusive), printing stars to form the right half of each row.
5. After each row is complete, a print() statement is used to move to the next line and start a new row.
This part of the code creates the lower half of the pyramid, which is an inverted version of the upper half.
1. The outer loop iterates from 4 to 1 (inclusive) in reverse order using the range(4, 0, -1) construct.
2. The first inner loop (for j in range(i, 5, 1):) prints spaces before the first set of stars. The number of spaces increases by 1 in each iteration as j counts up from the current value of i to 4 (excluding 5).
3. The second inner loop (for k in range(0, i):) prints the first set of stars. It starts from 0 and goes up to the current value of i, printing stars to form the left half of each row.
4. The third inner loop (for m in range(1, i):) prints the second set of stars. It starts from 1 and goes up to the current value of i (excluding i), printing stars to form the right half of each row.
5. Again, a print() statement is used to move to the next line after each row.

💯 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.
