Browse other questions tagged python beginner python-3.x fibonacci-sequence or ask your own question. The iterator is an abstraction, which enables the programmer to accessall the elements of a container (a set, a list and so on) without any deeper knowledge of the datastructure of this container object.In some object oriented programming languages, like Perl, Java and Python, iterators are implicitly available and can be used in foreach loops, corresponding to for loops in Python. As the name may already reveal, it works basically like a Fibonacci, but summing the last 3 (instead of 2) numbers of the sequence to generate the next. In Mathematics, Fibonacci Series in a sequence of numbers such that each number in the series is a sum of the preceding numbers. Also, the generator example makes a list of all the 200000 fibonacci numbers whereas the iterative one just returns the 200,000th fibonacci. And a second function to cycle through all the numbers weâve generated. To understand this demo program, you should have the basic Python programming knowledge.
