Are lists dynamic in Python?
Implementation of Dynamic Array in PythonWhat is a dynamic array? A dynamic array is similar to an array, but with the difference that its size can be dynamically modified at runtime. Dont need to specify how much large an array beforehand. The elements of an array occupy a contiguous block of memory, and once created, its size cannot be changed. A dynamic array can, once the array is filled, allocate a bigger chunk of memory, copy the contents from the original array to this new space, and continue to fill the available slots.

Well be using a built in library called ctypes of python . Check out the documentation for more info, but its basically going to be used here as a raw array from the ctypes module. A quick note on public vs private methods, we can use an underscore _ before the method name to keep it non-public. For example:
The key is to provide means to grows an array A that stores the elements of a list. We cant actually grow the array, its capacity is fixed. If an element is appended to a list at a time, when the underlying array is full, we need to perform following steps.
Dynamic Array Code Implementation:
Awesome, we made our own dynamic array! Play around with it and see how it auto-resizes.
