self.count += 1 append操作的视觉表示如下:删除操作与单向链表不同,我们需要在遍历整个列表的时候跟踪先前遇到的节点,双向链表避免了这一步。这是通过使用前一个指针实现的。从双向链表中删除节点的算法在完成节点删除之前,为基本上四种情况提供了支持。这些是:...

digit是一个被PYLONG_BITS_IN_DIGIT宏控制的类型,在编译 Python 解释器时可以通过修改这个宏来指定其类型;如果没有指定PYLONG_BITS_IN_DIGIT宏的值,则默认会根据操作系统的类型来决定,当指针占用 8 字节以上空间时(64 位以上操作系统),PYLONG_BITS_IN_DIGIT = 30,digit即为uint32_t,否则PYLONG_BITS_IN_...

We may ask ourselves how usefulexample 14is. Well, think about the stringcount()method which returns the number of times a substring occurs in a string. Example 15: def substring_freq(s, substr): return s.count(substr) def substring_freq_2(s, substr): ...
