Marymount University Use of the Queue Functions in a Python Program Project
Instruction are on the code for what you should do see the codes below
class Stack:
data=[]
def is_empty(self):
return self.data==[]
def push(self, node):
self.data.append(node)
def pop(self):
if not self.is_empty():
value=self.data[-1]
del self.data[-1]
return value
else:
print(“Nothing to pop”)
def print_stack(self):
print(‘not implemented yet’)
print(‘print the stack vertical so that the top is printed first’)
fruit = Stack()
fruit.pop()
fruit.push(“Apple”)
fruit.push(“Banana”)
fruit.pop()
fruit.push(“Canned Yams”)
fruit.push(“Durian”)
fruit.print_stack()
fruit.pop()
fruit.pop()
fruit.print_stack()
“””
Finish the Stack Class so that the print_stack method prints the stack vertically so that for instance [‘a’,’b’,’c’] is printed
a
b
c
“””
class Queue:
data=[]
“””
Write Queue functions for enqueue, dequeue, is_empty and print_queue
“””
q=Queue()
q.enqueue(‘Job 1’)
q.enqueue(‘Job 2’)
q.enqueue(‘Job 3’)
q.print_queue()
q.dequeue()
q.dequeue()
q.print_queue()
