Solution Review: Creating Fibonacci Sequence Using Generator

Understand how to implement the Fibonacci sequence using a generator in Python. Learn to initialize variables, use the yield keyword to output values iteratively, and update values within a loop. This lesson helps you grasp generator behavior and looping for efficient sequence generation.

We'll cover the following...

Solution

Python 3.5
def fib_gen(n):
    x, y = 0, 1
    for _ in range(n):
        yield x
        x, y = y, x + y
n = 10
gen = fib_gen(n)
print(list(gen))

Explanation

The first thing we need to do is declare our initial variables (x, y) at line 2 and assign them the values 0 and 1 which are the starting values for a Fibonacci sequence.

Next, since we have been provided with the ...
