Maintaining student details
like roll, name and per, using Queues (Using Functions)
Operations
Creation of empty queue
employee=[]
Addition of element
def add_element():
roll=input(“Enter roll “)
name=input(“Enter name “)
per=input(“Enter per “)
std=(roll,name,per)
student.append(std)
Deletion of element
if(student==[]):
print(“Underflow / student Queue in empty”)
else:
roll,name,per=student.pop(0)
print(“poped element is “)
print(“roll “,roll,” name “,name,” per “,per)
To check Queue is empty or not
if(student==[]):
print(“No Student /Queue is empty”)
else:
print(“Queue is not empty”)
Traversal operation
def traverse():
if not (student==[]):
n=len(student)
for i in range(0,n):
print(student[i])
else:
print(“Empty , No student to display”)
#queue implementation (using functions)
#program to create a queue of student(roll,name,per).
