The two access modes that are used when opening a file for input and output when pickling are rb and wb.
<h3>What is pickling?</h3>
Pickle is generally used in Python to serialize and deserialize a Python object structure. In other words, it is the act of transforming a Python object into a byte stream in order to save it to a file/database, maintain program state across sessions, or transport data over a network. By unpickling the pickled byte stream, the original object hierarchy can be recreated. This entire procedure is comparable to object serialization in Java or .Net.
When a byte stream is unpickled, the pickle module first makes an instance of the original object before populating it with the right data. To accomplish this, the byte stream only carries data relevant to the original object instance.

Answer:
The design and development process:
The design and development is the interface of a great variety of skills and expertise in the users developer and domain experts. It is common objective of designing the innovative and useful software. Where design is the process of designing the components and data to satisfy the requirements. And development is the process of creating the system used to develop them.
The three main phases for design and development process are:
- The user requirements and interaction of technology analysis.
- Development of the system.
- Iterative design and prototyping
