Queue implementation with functions
To maintain number/elements in the form of a Queue
Creation of empty queue
q=[]
Addition of element
def add():
a=input(“Enter any element “)
q.append(a)
Deletion of element
def delete():
if(q==[]):
print(“Underflow / queus is empty”)
else:
print(“poped element is “,q[0])
q.pop(0)
To check Queue is empty or not
if(q==[]):
print(“Queue is empty”)
else:
print(“Queue is not empty”)
Travesal operation
def traverse():
n=len(q)
if(n==0):
print(“queue is empty”)
else:
for i in range(0,n):
print(q[i])
