creating a playing card Class Python

问题 I created a playing card object that has certain attributes of rank, suite and blackjack value. The blackjack value part keep getting a TypeError that says I can't compare between instances of list and int . I'm not sure how to resolve (how to/if I can compare just the index of the list and then give it the blackjack value based on its index)? Does the if/elif block belong within the bjValue() function or in the init () function? Here's my code: class Card: """playing card object where

Java class with no constructor?

由 强颜欢笑 提交于 2019-12-31 06:37:45
问题 I have this class class Customer{ int ID; Time arriveTime; Time serviceTime; Time completeTime; int transaction; } Don't I need a constructor in order to set the values inside? I will be using this class to hold different values while making an array of Customers. Wouldn't this mean I would need this in order to set the values? public Customer(int id, Time arrive, Time service, Time complete, int trans){ ID = id; arriveTime = arrive; serviceTime = service; completeTime = complete; transaction

Swift class de-initialized at end of scope instead of after last usage

由 纵饮孤独 提交于 2019-12-31 06:22:43
问题 I've asked this question asking about the guarantees of the lifetime of a reference in a local variable and was referred to this thread in which the exact semantics of the lifetime of references to class instances were discussed. AFAICT from that thread, a class instance may be de-initialized right after the last usage of a variable containing the last reference, even before other expressions in the same statement are evaluated. It is argued there that allowing this behavior is necessary to
