Operations on Stack

A list contains the following record of a customer: [Customer_name, Phone_number, City]

Write the following user-defined functions to perform given operations on the stack named ‘status’:

1. Push_element() - Push an object containing the name and Phone number of customers who live in Goa to the stack.
2. Pop_element() - Pop the objects from the stack and display them. Also, display “Stack Empty” when there are no elements in the stack.

For example:

If the lists of customer details are:

[“Gurdas”, “99999999999”,”Goa”]
[“Julee”, “8888888888”,”Mumbai”] [“Murugan”,”77777777777”,”Cochin”]
[“Ashmit”, “1010101010”,”Goa”]

The stack should contain

[“Ashmit”,”1010101010”]
[“Gurdas”,”9999999999”]

The output should be:

[“Ashmit”,”1010101010”]
[“Gurdas”,”9999999999”]
Stack Empty

Write a function in Python, Push(SItem) where SItem is a dictionary containing the details of stationery items - {Sname:price}. The function should push the names of those items in the stack that have a price greater than 75. Also, display the count of elements pushed into the stack.

For example:

If the dictionary contains the following data:

Ditem={"Pen":106,"Pencil":59,"Notebook":80,"Eraser":25}

The stack should contain
Notebook
Pen

The output should be:
The count of elements in the stack is 2

State TRUE or FALSE for the following case:

PUSH operation may result into underflow condition.

Find the output of the following code:

result=0
 numberList=[10,20,30]
 numberList.append(40)
 result=result+numberList.pop()
 result=result+numberList.pop()
 print(“Result=”,result)

Write a program to create a Stack for storing only odd numbers out of all the numbers entered by the user. Display the content of the Stack along with the largest odd number in the Stack. (Hint. Keep popping out the elements from stack and maintain the largest element retrieved so far in a variable. Repeat till Stack is empty).
