To solve this challenge, we need to split the challenge into a base case (the point at which we stop performing operations) and a recursive case (the base case is not yet reached, so the function calls itself in such a way that we approach — and eventually reach — the base case). Solution #2 ⌗. … Step 3: Finally, the Fibonacci sequence for the given limit will be displayed in the new window. We can implement Binet's formula in Python using a function: def fibBinet (n): phi = (1 + 5**0.5)/2.0. Let's say you are given a list of names, and you have to print a list that contains the length of each name.
