Likewise ,it goes on until it reaches the number of the elements in the series. In python, it has following steps. This Fibonacci series program starts with getting the number of elements for the series.  Next, it assigns the values to the first two numbers.  It checks the number of elements is less than zero. If yes means, the number is a negative value. So, it prints a message that enter a positive number. Else if the number of elements is equal to 1, it print the the first number alone. Else, it starts a loop. It prints the first value. It adds the previous two numbers and store it into third variable.
