2. In Python, every object has its unique state. We give each object its unique state by creating attributes in the __init__method of the class. Example: Number of doors and seats in a car. 3. Behaviour of an object is what the object does with its attributes. We implement behavior by creating methods in the class. The process involves two different steps: first you have to create a module or a class in Python and you have to import these classes or modules to another Python file. Step 1: How to create Module and Classes in Python. Before importing the class from the user-defined module, a Python file should be created by the user into the main program.Python is an object-oriented programming (OOP) language, which means it is centered around the idea of “objects” that can contain data (such as attributes) and code …By Rachel Pannett.
