Fibonacci series creation in Python
Learn how to write program for Fibonacci series . This is important programming and asked in many pairs programming interviews .
Lets break this down
Here I try to solve this program using recursive practice.
at step 1 : have declared the list having two element 0 and 1 .
as per Fibonacci equation : xn= xn-1 + xn-2
in next steps
created the loop for iterate the length and append the values.
def fibonacci(n): fib_series = [0, 1] # Starting with the first two numbers in the series
for i in range(2, n): next_num = fib_series[i - 1] + fib_series[i - 2] fib_series.append(next_num)
return fib_series
n = 10fibonacci_series = fibonacci(n)print(f"Fibonacci series with {n} numbers:", fibonacci_series)
# Output: Fibonacci series with 10 numbers: [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]
