In Python, the for loop is particularly versatile and user-friendly. It directly iterates over items of any sequence (such as a list or string), in the order that they appear, without requiring the indexing used in some other languages. This feature simplifies the process of looping through ...
deque是为了高效实现插入和删除操作的双向列表,适合用于队列和栈: fromcollectionsimportdeque q= deque(['a','b','c']) q.append('x') q.appendleft('y')print(q)#['y', 'a', 'b', 'c', 'x'] 注:deque除了实现list的append()和pop()外,还支持appendleft()和popleft(),这样就可以非常高效地...
