在实现冒泡排序算法时,知道交换的次数是很重要的。要对诸如[3, 2, 1]的数字列表进行排序,我们需要最多交换两次元素。这等于列表长度减 1,iteration_number = len(unordered_list)-1。我们减去1是因为它恰好给出了最大迭代次数: 通过在精确两次迭代中交换相邻元素,最大的数字最终位于列表的最后位置。 if 语句确...
如果我们可以在Contributor类上添加一个contributor_type属性就好了,但是当处理多才多艺的人既写书又导演电影时,这种方法就会失效。 一个选择是向我们的LibraryItem子类中添加属性来保存我们需要的信息,比如Book上的Author,或者CD上的Artist,然后将这些属性的关系都指向Contributor类。问题在于,我们失去了很多多态的优雅。...

首先,我们将使用一组库来进行经典的图像处理:从提取图像数据开始,使用一些算法转换数据,使用库函数进行预处理、增强、恢复、表示(使用描述符)、分割、分类、检测和识别(对象)以进行分析、理解,并更好地解释数据。接下来,我们将使用另一组库来进行基于深度学习的图像处理,这是一种在过去几年中非常流行的技术。 图像...

For that, our work has been made a lot simpler by thepython-chesslibrary which will provide us with all of the move generation and validation. So, let’s start by installing it. 在为引擎编写任何算法之前,对我们来说,对棋子背后的逻辑进行编码非常重要,也就是说,将每一个可能的合法举动分配给每...
No matter what field your child goes into, learning to code will help set them up for success. That said, a strong background in coding is particularly useful for careers in software development, web design, game dev, AI, and cybersecurity. Learn more aboutwhat makes coding a good career...
