Create a stack implementation using deques in order to run using the following outline using python. Take into consideration any special cases. Using push_front to add onto the stack, pop_front to remove from a stack and peek_front to peek at a stack.

class Stack:

def __init__(self): self._deque = Deque()

def __str__(self): return str(self._deque)

def __len__(self): return len(self._deque)

def push(self, val): #implement code here

def pop(self): #implement code here

def peek(self): #implement code here
