在Python3中,可以使用命名空间和ElementTree模块来生成XML文档。 首先,命名空间(Namespace)是一种用于标识XML元素和属性的唯一性的机制。它可以避免不同XML文档中的元素和属性名称冲突。在Python中,可以使用ElementTree模块来处理XML文档,并通过命名空间来创建具有唯一标识符的元素和属性。 ElementTree是
elements():返回迭代器,其中每个元素出现计数值所指定次<1则自动忽略 most_common():由频率高到低排序返回(元素,次数) subtract():减去元素 fromkeys(): 数据结构 双向队列(deque) collection中的deque类是一种双向队列 头部尾部插入或移除一个元素,只消耗常数级别的时间,适合FIFO的队列 虽然list也可做到,但是list...
