name=input(“Enter name “)
sal=input(“Enter sal “)
emp=(empno,name,sal)
employee.append(emp)

empno,name,sal=employee.pop(0)
print(“poped element is “)
print(“empno “,empno,” name “,name,” salary “,sal)
To check Queue is empty or not
if(employee==[]):
print(“No Employee /Queue is empty”)
else:

def traverse():
if not (employee==[]):
n=len(employee)
for i in range(0,n):
print(employee[i])
