Python has a whole slew of magic methods designed to implement intuitive comparisons between objects using operators, not awkward method calls. They also provide a way to override the default Python behavior for comparisons of objects (by reference). Here's the list of those methods and what the...
A Unicode string is turned into a sequence of bytes that contains embedded zero bytes only where they represent the null character (U+0000). This means that UTF-8 strings can be processed by C functions such asstrcpy()and sent through protocols that can't handle zero bytes for anything oth...

在将一个PyStringObject对象a的PyObject指针作为key和value添加到interned中时,PyDictObject对象会通过这两个指针对a的引用计数进行两次加1的操作。但是Python的设计者规定在interned中a的指针不能被视为对象a的有效引用,因为如果是有效引用的话,那么a的引用计数在Python结束之前永远都不可能为0,因为interned中至少有两...
