Using frozenset to create a key from kwargs is generally fine, but it assumes that all keyword arguments are hashable. If there's a possibility of non-hashable types being passed as keyword arguments, this could raise an error. Consider handling such cases or documenting this requirement.

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