Question

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

Answer 1

status=[]
def Push_element (cust) :
      if cust[2]=="Goa":
           L1=[cust[0], cust[1]]
           status.append (L1)

def Pop_element ():
     num=len (status)
     while len(status)!=0:
        dele=status.pop ()
        print (dele)
        num=num-1
else:
       print("Stack Empty")
