🐍 Python Pattern Challenge — Day 19

Pattern printing is a simple way to improve your Python loops, spacing, repetition, and logical thinking. For Day 19, let's create a simple Right-Side Arrow Star Pattern ⭐.

This pattern is easy to understand but still gives you good practice with increasing and decreasing star counts.

🎯 Today's Challenge

Write a Python program to print:

Best and cleanest code will be rewarded! 🏆

Solution 1 — Using for Loop

n = 6

for i in range(1, n + 1):
    print("* " * i)

for i in range(n - 1, 0, -1):
    print("* " * i)

How it works

The first loop increases the number of stars:

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

The second loop decreases them:

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

Together, they create the complete arrow pattern.

Solution 2 — Using a Single Loop

n = 6

for i in list(range(1, n + 1)) + list(range(n - 1, 0, -1)):
    print("* " * i)
The sequence:

[1, 2, 3, 4, 5, 6, 5, 4, 3, 2, 1]

controls how many stars are printed on each row.

---

Solution 3 — Using a Function

def star_arrow(n):

    for i in list(range(1, n + 1)) + list(range(n - 1, 0, -1)):
        print("* " * i)


star_arrow(6)

Now you can easily change the size:

star_arrow(10)

and create a larger pattern.

⚡ Short & Clean Code

for i in [1,2,3,4,5,6,5,4,3,2,1]:
    print("* " * i)

🔥 Just one loop creates the complete pattern.

🚀 Challenge Yourself

Can you modify this pattern:

• Take the size using input()?
• Create it using a while loop?
• Reverse the arrow?
• Replace * with # or another symbol?
• Create a hollow version?
• Move the pattern toward the left or right?
