 if len(MyStack) > 0:
  MyStack.pop()
 else:
  print("Stack is empty.")
 
Q6. Write add(bookname) and delete() method in python
 to add bookname and remove bookname considering
them to act as push() and pop() operations in stack.
Ans.
MyStack=[]

def delete(MyStack):
 if len(MyStack) > 0:
  MyStack.pop()
 else:
  print("Stack is empty. There is no book name")
 
Q7. Write addclient(clientname) and remove()
methods in python to add new client and delete
existing client from a list "clientdetail",
considering them to act as push and pop
operations of the stack.

Ans. 

clientdetail=[]

def addclient(cn):

   clientdetail.append(cn)

def remove():

   if len(clientdetail)>0:

      clientdetail.pop()

   else:
