Write AddCustomer(Customer) and DeleteCustomer(Customer) methods in Python to add a new Customer and delete a Customer from a List of CustomerNames, considering them to act as push and pop operations of the Stack data structure.
Answer
def AddCustomer(Customer):
Customer_name = input("Enter the customer name: ")
Customer.append(Customer_name)
def DeleteCustomer(Customer):
if Customer == []:
print("Customer list is empty")
else:
print("Deleted Customer name:", Customer.pop())
Customer = []
AddCustomer(Customer)
AddCustomer(Customer)
AddCustomer(Customer)
print("Initial Customer Stack:", Customer)
DeleteCustomer(Customer)
print("Customer Stack after deletion:", Customer)Output
Enter the customer name: Anusha
Enter the customer name: Sandeep
Enter the customer name: Prithvi
Initial Customer Stack: ['Anusha', 'Sandeep', 'Prithvi']
Deleted Customer name: Prithvi
Customer Stack after deletion: ['Anusha', 'Sandeep']

Write a program that, depending upon the user's choice, either pushes or pops an element in a Stack. The elements are shifted towards the right so that the top always remains at 0th (zeroth) index.
Write a program to insert or delete an element from a Queue depending upon the user's choice. The elements are not shifted after insertion or deletion.
Two lists Lname and Lage contain name of person and age of person respectively. A list named Lnameage is empty. Write functions as per details given below:
- Push_na(): It will push the tuple containing pair of name and age from Lname and Lage whose age is above 50.
- Pop_na(): It will remove the last pair of name and age and also print name and age of the removed person. It should also print "underflow" if there is nothing to remove.
For example, the two lists have the following data:
Lname=['Narender', 'Jaya', 'Raju', 'Ramesh', 'Amit', 'Piyush' ]
Lage= [45, 23, 59, 34, 51, 43]After Push_na() the Lnameage Stack contains:
[('Raju', 59), ('Amit', 51)]
The output of first execution of Pop_na() is:
The name removed is Amit
The age of person is 51A dictionary stu contains rollno and marks of students. Two empty lists stack_roll and stack_mark will be used as Stack. Two functions Push_stu() and Pop_stu() are defined and perform the following operation:
- Push_stu(): It reads dictionary stu and adds keys into stack_roll and values into stack_marks for all students who secured more than 60 marks.
- Pop_stu(): It removes last rollno and marks from both list and prints "underflow" if there is nothing to remove.
For example,
stu={ 1 : 56, 2 : 45, 3 : 78, 4 : 65, 5 : 35, 6 : 90 }
Values of stack_roll and stack_mark after push_stu() function:
[3, 4, 6] and {78, 65, 90}
