If no argument is given, the constructor returns an empty tuple. If iterable is specified the tuple is initialized from iterable's items. If the argument is a tuple, the return value is the same object.

It seems that the output you mentioned is not related to the code you provided. The code defines a class B with a property called "num", which can be used to get or set the values of four attributes (a, b, c, d) of an instance of the class B.
The line "test_ = B(1, 2, 3, 4)" creates an instance of the class B with initial values of 1, 2, 3, and 4 for its four attributes.
Unless there is some other code that you did not provide, there should be no output from running this code.

改写代码风格并保持变量名不变class LinkedList: class Node: def __init__(self, val, prior=None, next=None): self.val = val self.prior = prior self.next = next def __init__(self): self.head = LinkedList.Node(None) # sentinel node (never to be removed) self.head.prior = self.head.next = self.head # set up "circular" topology self.length = 0
下面是改写后的代码风格:
```
class LinkedList:
class Node:
def __init__(self, val, prior=None, next=None):
self.val = val
self.prior = prior
self.next = next
def __init__(self):
self.head = LinkedList.Node(None) # Sentinel node (never to be removed)
self.head.prior = self.head.next = self.head # Set up "circular" topology
self.length = 0
```
注意,变量名没有改变,只是对代码进行了一些格式化和注释。
帮我把下面代码添加注释class Button: def __init__(self, text='按钮', left=0, top=0, width=90, height=30, color=(200, 200, 200)): self.text = text self.color = color self.rect = pygame.Rect(left, top, width, height) self.font = pygame.font.Font(r"C:\Windows\Fonts\simsun.ttc", 16) self.text_surface = self.font.render(self.text, True, (0, 0, 0)) self.text_rect = self.text_surface.get_rect() # self.text_rect.center = self.rect.center self.active = False self.function = None button_group.append(self) def set_text(self, new_text): self.text = new_text self.text_surface = self.font.render(self.text, True, (0, 0, 0)) self.text_rect = self.text_surface.get_rect() def draw(self, screen): if self.active: pygame.draw.rect(screen, (180, 180, 200), self.rect, 0) else: pygame.draw.rect(screen, self.color, self.rect, 0) self.text_rect.center = self.rect.center screen.blit(self.text_surface, self.text_rect) def get_click(self, event): if event.type == pygame.MOUSEBUTTONDOWN: if event.button == 1: mx, my = event.pos if self.rect.left <= mx <= self.rect.right and self.rect.top <= my <= self.rect.bottom: self.active = True elif event.type == pygame.MOUSEBUTTONUP and self.active: if event.button == 1: mx, my = event.pos if self.rect.left <= mx <= self.rect.right and self.rect.top <= my <= self.rect.bottom: # print(f'{self.text}按钮被点击') if callable(self.function): self.function() self.active = False def click_connect(self, function): self.function = function
