可以使用以下代码进行简化缩短:
```javascript
const numbers = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"];
for (let i = 0; i < numbers.length; i++) {
const number = numbers[i];
const selector = `.flip .number${i}:before, .flip .number${i}:after`;
const style = `content: "${number}";`;
document.styleSheets[0].insertRule(`${selector} { ${style} }`, 0);
}
```
这样可以用一个数组来存储数字,然后使用循环来动态生成选择器和样式,并且把它们插入到页面样式表中。

torch.flip 示意图
抱歉,根据提供的引用内容,没有找到关于torch.flip的示意图。但是我可以为您提供关于torch.flip的介绍和示例代码。
torch.flip函数是PyTorch中的一个张量操作函数,用于沿指定维度翻转张量的元素顺序。它可以在水平、垂直或深度方向上翻转张量的元素。
以下是一个示例代码,展示了如何使用torch.flip函数进行张量翻转:
```python
import torch
# 创建一个3x3的张量
tensor = torch.tensor([[1, 2, 3],
[4, 5, 6],
[7, 8, 9]])
# 沿水平方向翻转张量
flipped_tensor = torch.flip(tensor, [1])
print("原始张量:")
print(tensor)
print("翻转后的张量:")
print(flipped_tensor)
```
输出结果为:
```
原始张量:
tensor([[1, 2, 3],
[4, 5, 6],
[7, 8, 9]])
翻转后的张量:
tensor([[3, 2, 1],
[6, 5, 4],
[9, 8, 7]])
```
在上面的示例中,我们创建了一个3x3的张量,并使用torch.flip函数沿水平方向翻转了张量的元素顺序。
pygame.transform.flip
pygame.transform.flip() is a method in the Pygame library that is used to flip an image along its axis. This method can be used to create mirror images or to change the orientation of an image. The method takes three arguments: the image to be flipped, a boolean value indicating whether to flip the image horizontally, and a boolean value indicating whether to flip the image vertically.
Syntax:
```
pygame.transform.flip(surface, xbool, ybool)
```
- surface: The image to be flipped.
- xbool: A boolean value indicating whether to flip the image horizontally (True or False).
- ybool: A boolean value indicating whether to flip the image vertically (True or False).
Example:
```
import pygame
pygame.init()
# Set up the display
display_width = 640
display_height = 480
game_display = pygame.display.set_mode((display_width, display_height))
# Load the image
my_image = pygame.image.load("image.png")
# Flip the image horizontally
flipped_image = pygame.transform.flip(my_image, True, False)
# Display the original and flipped images
game_display.blit(my_image, (0, 0))
game_display.blit(flipped_image, (display_width/2, 0))
pygame.display.update()
# Quit the game
pygame.quit()
```
In the above example, we first load an image using the `pygame.image.load()` method. We then use the `pygame.transform.flip()` method to create a flipped version of the image by passing in `True` as the first argument to indicate that we want to flip the image horizontally. We then display both the original and flipped images using the `blit()` method. Finally, we update the display and quit the game.
