Need help with python.

In python add a method to this code provided that reverses the contents of the stack. Thanks! class Stackt: def__init__(self): #creating an empty list self.list=[] def push (self, item): #append to list self.list.append(item) def pop(self): #dont mention what you want to pop return self.list.pop() def peek(self): return self.list[len(self.list)-1] def size(size): #return len of list return len(self.list) def is__empty (self): if len(self.list)--0: return True else: return False s1=Stack() s1.push(5) s1.push(6) s1.push(7) class Stack: def__init__(self): #creating an empty list self.list=[] def push(self, item): #append to list self.list.append(item) def pop(self): #dont mention what you want to pop return self.list.pop() def peek(self): #return self.list[len(self.list)-1] def size(self): #return len of list return len(self.list) def is__empty(self): if len(se1f.list)==0: return True else: return False s1=Stack() s1.push(5) s1.push(6) s1.push(7) print(s1.peek()) print(s1.size())
