class Stack: # we are using a list to create a stack # so when we create a new stack object, we will start # with empty list def __init__(self): self.s =  def push(self,item): # use the list method to put the item into the list self.s.append(item) def pop(self): # get the item at the top # print that item # delete that from that index in the return self.s.pop() def peek(self): # print the item at the top of the stack # do not delete it return self.s[-1] def isEmpty(self): # check if the stack is empty return len(self.s) == 0 def size(self): # print the size of the stack return len(self.s)
