Python Star Pattern 11

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, 0, -1):
        print("*",end="")
    for k in range(i, 5):
        print(" ",end="")
    for m in range(i, 5, 1):
        print(" ",end="")
    for n in range(0, i):
        print("*",end="")
    print()
		
for i in range(1, 5):
    for j in range(0, i+1):
        print("*",end="")
    for k in range(i, 4):
        print(" ",end="")
    for m in range(i, 4):
        print(" ",end="")
    for n 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 program generates the top half of the pattern. Let's go through it step by step:
1. The outer loop for i in range(5, 0, -1): runs from 5 down to 1 (inclusive on the starting value, exclusive on the ending value) in reverse order.
2. The first inner loop for j in range(i, 0, -1): prints '*' character i times.
3. The second inner loop for k in range(i, 5): prints spaces ' ' 5 - i times, effectively creating a decreasing number of spaces as i increases.
4. The third inner loop for m in range(i, 5, 1): is similar to the second loop, also printing spaces ' ' 5 - i times. The range(i, 5, 1) is equivalent to range(i, 5).
5. The fourth inner loop for n in range(0, i): prints '*' character i times.
6. After all the loops, the print() statement is used to move to the next line, creating a new line for the next iteration of the outer loop.
Now, the second part of the program:
1. The outer loop for i in range(1, 5): runs from 1 to 4 (inclusive on the starting value, exclusive on the ending value).
2. The first inner loop for j in range(0, i+1): prints '*' character i+1 times.
3. The second inner loop for k in range(i, 4): prints spaces ' ' 4 - i times, creating an increasing number of spaces as i increases.
4. The third inner loop for m in range(i, 4): is again similar to the second loop, printing spaces ' ' 4 - i times.
5. The fourth inner loop for n in range(-1, i): prints '*' character i times. This loop has a starting value of -1, which has no effect since it is immediately followed by i.
6. The print() statement at the end of each iteration moves to the next line, creating a new 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.
