Create list of Fibonacci numbers after calculating Fibonacci series up to the number n which you will pass to a function as an argument. The number n must be input by the user.

Fibonacci numbers are calculated using the following formula: The first two numbers of the series are always equal to 1, and each consecutive number returned is the sum of the last two numbers.

Hint: Can you use only two variables in the generator function?

The code below will simultaneously switch the values of a and b.

a = 1

b = 2

a, b = b, a

The first number in the series should be 1. (The output will start like 1,1,2,3,5,8,…)
