🐍 Python Pattern Challenge — Day 21

Pattern printing is a great way to strengthen your Python loops, repetition, and logical thinking. For Day 21, let's keep things simple with a Growing Star Triangle ⭐.

🎯 Today's Challenge

Write a Python program to print exactly this pattern:

Can you create it with the cleanest Python code? 🏆

---

Solution 1 — Using a for Loop

for i in range(1, 11):
    print("* " * i)

How it works

The loop runs from 1 to 10.

On every iteration, i determines how many stars are printed:

"* " * i

So the number of stars increases row by row.

---

Solution 2 — Using a while Loop

i = 1

while i <= 10:
    print("* " * i)
    i += 1

Here, i starts at 1 and increases after every row until it reaches 10.

---

Solution 3 — Using a Function

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

star_pattern(10)

The function makes the pattern reusable.

For example:

star_pattern(5)

will create a smaller triangle.

⚡ Short & Clean Code

for i in range(1, 11): print("* " * i)

🔥 One line is enough to generate the complete pattern!

🚀 Challenge Yourself

Can you modify this pattern:

• Take the number of rows using input()?
• Print the pattern in reverse?
• Replace * with # or another character?
• Create the same pattern using nested loops?
• Make the triangle hollow?
