The PlayGame method has such a keyword guard. In fact, gaurd serves as a guard. For example
guard numOfMyFriend > 0 else { throw errorGame.noFriendToGether }The following program can be executed only when numOfMyFriend> 0. Otherwise, an exception is thrown. Like Uncle Zhang said, is there a card? Cards can be used to enter the door.

List
A built-in data type in Python is list: list. List is an ordered set that allows you to add and delete elements at any time.
For example, you can use a list to list the names of all the students in the class:
>>> classmates = ['Michael', 'Bob', 'Tracy']>>> classmates['Michael', 'Bob', 'Tracy']
The variable classmates is a list
