本文主要是介绍Python模拟队列,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
# 创建队列 q = [] maxSize,front,rear = 100,0,0 # 占位 for i in range(maxSize): q.append(0) # 这两个函数我承认我是从我写的C++函数改的 # 进队 def push(value): global rear,q # 如果队不满则添加值 if(rear < maxSize): q[rear] = value rear += 1 # 出队 def pop(): global front # 如果队首不为队尾(即不为空),则front+1 if(front != rear): front += 1 # 啥也没干 print('q:',q) print('rear: %d\tfront: %d' % (rear,front)) # 先入队 for i in range(1,6): push(i) print('q:',q) print('rear: %d\tfront: %d' % (rear,front)) # 再出队 pop() print('q:',q) print('rear: %d\tfront: %d' % (rear,front))
q: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] rear: 0 front: 0 q: [1, 2, 3, 4, 5, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] rear: 5 front: 0 q: [1, 2, 3, 4, 5, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] rear: 5 front: 1
