Fibonacci Series with Python

Fibonacci Series

 Fibonacci Series are the numbers in the following integer sequence, called the Fibonacci series , and characterized by the fact that every number after the first two is the sum of the two preceding ones:-

${\displaystyle 1,\;1,\;2,\;3,\;5,\;8,\;13,\;21,\;34,\;55,\;89,\;144,\;\ldots }$

      Often, especially in modern usage, the sequence is extended by one more initial term:

${\displaystyle 0,\;1,\;1,\;2,\;3,\;5,\;8,\;13,\;21,\;34,\;55,\;89,\;144,\;\ldots }$

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.
