I have a python function and a decorator that works just fine.
def fun_cache(function):
memo = {}
def wrapper(*args):
if args in memo:
return memo[args]
else:
rv = function(*args)
memo[args] = rv
return rv
return wrapper
@fun_cache
def fib(n):
if (n < 2): return 1
else: return fib(n-1) + fib(n-2)
assert(fib(0) == 1)
assert(fib(3) == 3)
assert(fib(6) == 13)
assert(fib(10) == 89)
assert(fib(30) == 1346269)
assert(fib(100) == 573147844013817084101)
assert(fib(400) ==
284812298108489611757988937681460995615380088782304890986477195645969271404032323901)
Now I will like to call the @fun_cache decorator like this :
@fun_cache(cache={})
Any help?
