Write a program to find Fibonacci series of n numbers in Python.

 In mathematics, the Fibonacci numbers or Fibonacci sequence are the numbers in the following integer sequence:

01, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144.....

The Fibonacci spiral: an approximation of the golden spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34.

By definition, the first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two.
