The return type annotation for the inner function should not be Callable. Since inner is a wrapper function that returns the result of func, its return type should match the return type of func. You can use Any as a return type to accommodate any return type from func.

if key in cache_storage:
print("Getting from cache")
return cache_storage[key]
else:
print("Calculating new result")
result = func(*args, **kwargs)
cache_storage[key] = result
return result

return inner
