The result dictionary is defined at the function level, which means it will be shared across all instances of the decorated function. This is fine if the decorator is used on a single function, but if used on multiple functions, their results will be mixed. Consider using a more robust solution if the decorator is intended for multiple functions.

def wrapper(*args) -> Any:
if args not in result:

Using args as a key in the dictionary assumes that all arguments are hashable. If the function accepts non-hashable arguments (like lists or dictionaries), this will raise a TypeError. Consider handling such cases or documenting that the decorator only works with hashable arguments.

print("Calculating new result")
result[args] = func(*args)
else:
print("Getting from cache")
return result[args]
return wrapper
