🚀 Day 31/150 – Fibonacci Series in Python

The Fibonacci series is a sequence where each number is the sum of the previous two numbers.
Example: 0, 1, 1, 2, 3, 5, 8, 13...

Let’s explore different ways to print Fibonacci series in Python 👇

---

🔹 Method 1 – Using for Loop

n = 10
a, b = 0, 1

for i in range(n):
    print(a, end=" ")
    a, b = b, a + b

✅ Most common and efficient method.

🔹 Method 2 – Taking User Input

n = int(input("Enter number of terms: "))
a, b = 0, 1

for i in range(n):
    print(a, end=" ")
    a, b = b, a + b

✅ Useful for dynamic programs.

🔹 Method 3 – Using while Loop

n = 10
a, b = 0, 1
count = 0

while count < n:
    print(a, end=" ")
    a, b = b, a + b
    count += 1

✅ Great for loop practice.

🔹 Method 4 – Using Recursion

def fib(n):
    if n <= 1:
        return n
    return fib(n - 1) + fib(n - 2)

for i in range(10):
    print(fib(i), end=" ")

✅ Best for learning recursion concepts
