Python interview questions for freshers

Python ships with numeric types (int, float, complex), sequences (str, list, tuple, range), mappings (dict), sets (set, frozenset), booleans, bytes/bytearray, and None.

A list is a mutable ordered sequence, so you can append, pop, and assign by index.

A dict maps hashable keys to values and gives average O(1) lookup.

A set is an unordered collection of unique hashable items.

Mutable objects such as list, dict, and set can change in place after creation.

None is the singleton that means 'no value' and is the default return of a function that does not return anything.

The == operator calls equality logic, usually __eq__, and compares values.

A class is a blueprint that groups data and behavior into objects.

__init__ is the instance initializer that runs after the object is created.

self is the conventional first parameter of an instance method and refers to the instance the method was called on.

Inheritance lets a subclass reuse and extend a parent class's attributes and methods.

Encapsulation means grouping state with the methods that use it and hiding internals behind a public interface.

An instance method receives the instance as self and works with per-object state.

MVT stands for Model, View, Template.

A view is a callable that takes an HttpRequest and returns an HttpResponse.

A template is an HTML file with Django template language tags and filters.

urls.py maps URL patterns to views using path() or re_path().

Django admin is a built-in CRUD interface generated from your models.

A project is the whole site: settings, root URLconf, and WSGI/ASGI entry points.

The ORM maps Python classes to database tables so you query with Python instead of raw SQL.
