creat a new EnhancedBudget class, do the following:

• add a new class attribute, transactions. This should be initialized when the EnhancedBudget is created and should default to being an empty dictionary ({}). This dictionary will have budget categories as its keys and the values associated with each key will be a list of the transactions (in dollars) logged for that category.
• add a new class method, log_transaction, that takes two inputs: category and amount. Using these two inputs, this method should for the following:
  1. Check to see if the provided category is already in the transactions dictionary.
  2. If it is, it should append the amount to the list of amounts that already exist in that category.
  3. If it isn't already in the transactions dictionary, it should create a new list associated with that category key with the amount as the first entry in the list.
