Due to version(python 2.7 or 3.x), as provided in the documentation consider using:
try:
from functools import lru_cache
except ImportError:
from backports.functools_lru_cache import lru_cache

While running the code below, I am getting the error that Python cannot import lru_cache. However, this happens with every import (math, etc...). I've tried every single tutorial I can find on the internet to try to get this thing to work. I've reinstalled Python. Pip and homebrew are installed as well.
#!usr/bin from functools import lru_cache import math fibonacci_cache = {} @lru_cache(maxsize = 1000) def fibonacci(n): if n == 1: return 1 elif n == 2: return 1 elif n > 2: return fibonacci(n-1) + fibonacci(n-2) for n in range(1, 501): print(n, ":", fibonacci(n))
The error:
