WebConstructors are special types of functions used to create and initialize objects in Python. Generators are special types of functions used to generate new values on demand. Constructors and Generators are two powerful features of the Python programming language that allow for improved code readability and efficiency. WebDefinition and Usage. The bytes () function returns a bytes object. It can convert objects into bytes objects, or create empty bytes object of the specified size. The difference between bytes () and bytearray () is that bytes () returns an object that cannot be modified, and bytearray () returns an object that can be modified.
