Create an Array class simulating the functionality of fixed-size arrays. The array’s size is 6. The array’s constructor is already defined:

class Array:

    def __init__(self):
        pass  # Dynamically added to avoid tampering
        self._count = 0
        self._array = [None, None, None, None, None, None]
        self._MAX_CAPACITY = 6

There is no need to implement the constructor. In the code editor, __init__ will contain pass. The constructor’s code will be added dynamically to avoid any changes.

The Array class should have the following methods:

• __len__(): Returns the length of the array. For example, if the array is [1, 2, None, None, None, None, None], __len__() will return 2.

• __getitem__(index): Returns the element at the specified index. Raises an IndexError when the index is out of range.

• emplace_back(element): Places an element at the back of the array. Raises an ArrayFull exception when the array is full (length > 6).

• emplace_front(element): Places an element at the front of the array. Raises an ArrayFull exception when the array is full (length > 6).

• emplace(element, index): Places an element at the specified index. Raises an ArrayFull exception when the array is full (length > 6).

Note: ArrayFull is already implemented. To raise it, simply use raise ArrayFull().
