## Code Before:

class Stack(object):
    def __init__(self):
        # Initialize stack as empty array
        self.stack = []

    # Return and remove the last element of the stack array.
    def pop(self):
        # If the stack is not empty, pop.
        if self.stack.length > 0:
            return self.stack.pop() 
## Instruction:
Add push method and implementation
## Code After:

class Stack(object):
    def __init__(self):
        # Initialize stack as empty array
        self.stack = []

    # Return and remove the last element of the stack array.
    def pop(self):
        # If the stack is not empty, pop.
        if self.stack.length > 0:
            return self.stack.pop() 

    # Add an element to the end of the stack array.
    def push(self, element):
        self.stack.append(element)
