This method capitalizes on the fact that sets in Python are implemented using a hash table, making membership tests highly efficient. By converting the original list back to a set, you eliminate duplicate elements, thereby reducing the number of membership checks needed. This approach is ...
Conversely, a deep copy should duplicate the original commands into an independent list object. At the same time, you want all copies to share the same global tab registry. Unfortunately, the default copy behavior won’t follow these rules. First of all, Python won’t automatically update the...
