NeoSOFT Python and Django Developer Interview Questions, Process, and Tips

List is a built-in Python data structure that can hold elements of different data types, while Array is a data structure from the NumPy library that can hold elements of the same data type.

• List is a dynamic array that can grow or shrink in size, while Array has a fixed size.

• List can hold elements of different data types, while Array can only hold elements of the same data type.

• List is a part of Python's standard librar...read more

DRF provides JSON, BrowsableAPI, TemplateHTML, and AdminRenderer classes for rendering responses.

• JSONRenderer: Renders data in JSON format.

• BrowsableAPIRenderer: Renders data in a browsable HTML format with forms for interacting with the API.

• TemplateHTMLRenderer: Renders data using a specified template in HTML format.

• AdminRenderer: Renders data in a format suitable for Django admin interface.

Method Resolution Order (MRO) is the order in which classes are searched for a method or attribute in Python.

• MRO is determined by the C3 linearization algorithm in Python.

• It follows a depth-first left-to-right traversal of the class hierarchy.

• MRO is important in multiple inheritance scenarios to resolve method conflicts.

• Example: class A: pass class B(A): pass class C(A): pass class D(B, C)

Class method is bound to the class itself, while static method is not bound to any specific instance or class.

• Class method takes 'cls' as the first parameter, allowing access to class variables and methods.

• Static method does not take any special parameters and does not have access to class or instance variables.

• Class method can be called on both the class and instances of the class.

• Static method is mainly used for util...read more

Transactions in SQL are a way to ensure data integrity by grouping multiple SQL statements into a single unit of work.

• Transactions help maintain the ACID properties (Atomicity, Consistency, Isolation, Durability) of a database.

• They allow multiple SQL statements to be executed as a single unit, either all succeeding or all failing.

• Transactions can be started with BEGIN TRANSACTION, COMMIT to save changes, or ROLLBACK to...read more

Decorators in Python are functions that modify the behavior of other functions or methods.

• Decorators are used to add functionality to existing functions without modifying their code.

• Types of decorators in Python include function decorators, class decorators, and method decorators.

• Example: @staticmethod and @classmethod are built-in decorators in Python.
