When a new object is created, the init method is automatically called, initializing the object and allocating memory for it. This method can also be utilized to set initial values for variables. Below is an example: Output: Hello, my age is…

Explain Inheritance and its types in Python with an example?
Python embraces the principles of object-oriented programming and allows classes to acquire the characteristics of another class, a concept known as inheritance. This facilitates code reuse, promoting efficiency. The original class from which properties are inherited is referred to as the superclass or parent class, while the class inheriting those properties is known as the…

What are python namespaces?
A Python namespace ensures that the names assigned to objects within a program are unique and can be used without conflict. In Python, namespaces are implemented as dictionaries where the object’s name serves as the key and the object itself serves as the value. Let’s examine some examples of namespaces:

What is the difference between modules and libraries ?
In Python, modules are like standalone files that house specific code components such as functions and variables. On the other hand, libraries are essentially vast collections of modules, and they come with pre-built functions and tools tailored for specific tasks or domains. These libraries not only simplify the development process but also enhance Python’s capabilities by providing…

What is PYTHONPATH?
PYTHONPATH serves as an environment variable within the Python programming language, empowering users to define supplementary directories for Python to search when seeking modules and packages. This variable serves as a search path and helps Python locate the necessary files to import when executing code. By setting the PYTHONPATH variable, users can extend the default…

What are the Key features of Python?
The key features of Python are as follows: For example, in Python, the following code line will run without any error:a = 100 a = “Intellipaat”

What distinguishes lists from tuples?
Lists Tuples Lists are mutable, i.e., they can be edited Tuples possess immutability, denoting their incapability of being modified like lists. Lists are usually slower than tuples Tuples are faster than lists Lists consume a lot of memory Tuples consume less memory when compared to lists Lists have a higher likelihood of experiencing unexpected changes,…

Python is an interpreted language or a hybrid language. Explain.
Python is an interpreted language. It is not a hybrid language, like languages that combine elements of both compiled and interpreted languages. In Python, the code is executed line by line by the Python interpreter.
