六十五、闪光地毯

原文：http://inventwithpython.com/bigbookpython/project65.html

斯坦利·库布里克执导的 1980 年心理恐怖片《闪光》发生在闹鬼的远眺酒店。酒店地毯的六边形设计成为这部著名电影的标志性部分。地毯的特点是交替和连锁的六边形，其催眠效果非常适合这样一部令人紧张的电影。这个项目中的短程序，类似于项目 35，“六边形网格”，在屏幕上打印这个重复的图案。

注意，这个程序使用原始字符串，它在开始的引号前面加上小写的r，这样字符串中的反斜杠就不会被解释为转义字符。

运行示例

当您运行shiningcarpet.py时，输出将如下所示：

_ \ \ \_/ ___ \ \ \_/ ___ \ \ \_/ ___ \ \ \_/ ___ \ \ \_/ ___ \ \ \_/ __
 \ \ \___/ _ \ \ \___/ _ \ \ \___/ _ \ \ \___/ _ \ \ \___/ _ \ \ \___/ _
\ \ \_____/ \ \ \_____/ \ \ \_____/ \ \ \_____/ \ \ \_____/ \ \ \_____/
/ / / ___ \_/ / / ___ \_/ / / ___ \_/ / / ___ \_/ / / ___ \_/ / / ___ \_

工作原理

创建这样的程序（或类似的第三十五个项目）并不是从编码开始，而是在文本编辑器中绘制镶嵌形状。一旦你写出了图案，你就可以把它切割成需要平铺的最小单元：

_ \ \ \_/ __
 \ \ \___/ _
\ \ \_____/
/ / / ___ \_
_/ / / _ \__
__/ / / \___

将这段文本复制并粘贴到源代码中后，您可以围绕它编写程序的其余部分。软件不仅仅是坐下来从头到尾写代码。每个专业软件开发人员都要经历几次反复的修补、实验和调试。最终的结果可能只有九行代码，但是一个小程序并不一定意味着花了很少的精力来完成它。

# Set up the constants:
X_REPEAT = 6  # How many times to tessellate horizontally.
Y_REPEAT = 4  # How many times to tessellate vertically.

for i in range(Y_REPEAT):
    print(r'_ \ \ \_/ __' * X_REPEAT)
    print(r' \ \ \___/ _' * X_REPEAT)
    print(r'\ \ \_____/ ' * X_REPEAT)
    print(r'/ / / ___ \_' * X_REPEAT)
    print(r'_/ / / _ \__' * X_REPEAT)
    print(r'__/ / / \___' * X_REPEAT)
