Let’s Begin Python Interview Question
Topics For Python Interview Questions
These could be the hot topics if you are a complete beginner and looking to start your career in python. We have given a general overview of each topic which can help you with your interview preparation if you are short on time.
What Are Python Literals?
In Python, literals are straightforward ways of expressing values. They represent basic data types such as integers, floats, booleans, strings, and more. These are extremely important when it comes to Python Interview Question. Here are some examples:
- String Literals: “halo”, ‘12345’
- Numeric Literals: 0, 1, 2, -1, -2, 3.14
- Boolean Literals: True or False
- Special Literals: None
- Unicode Literals: u”hello”
- List Literals: [], [5, 6, 7]
- Tuple Literals: (), (9,), (8, 9, 0)
- Dict Literals: {}, {‘x’: 1}
- Set Literals: {8, 9, 10}
Why do We Refer to Python as an Interpreted Language?
Python is an interpreted, interactive, and object-oriented programming language. It uses an interpreter to execute code and doesn’t require explicit type declarations. The emphasis is on readability with concise syntax. Python supports modules and packages for modularity and code reuse.
Tell us about PEP 8!
PEP 8, or Python Enhancement Proposal 8, is a set of guidelines for writing clean and readable Python code. It provides best practices for coding style and helps maintain consistency across projects.
What is the Namespace in Python?
A namespace in Python is a system that assigns a unique name to each object, such as variables or methods. It prevents naming conflicts and organizes names into local, global, and built-in namespaces.
What is a Python Path?
PYTHONPATH is an environment variable that allows users to add additional folders to the sys.path directory list for Python. It helps Python locate modules and packages.
What are Python Modules?
A Python module is a file containing Python code, including functions, classes, variables, and executable code. Modules help organize and structure code.
How do you declare Local and Global Variables?
Local variables are declared within a function and have scope only within that function. Global variables are defined outside any function and have a scope across the entire program.
What is a Flask?
Flask is an open-source web framework for building web applications. It is lightweight, flexible, and provides benefits like a built-in development server, rapid debugger, and unit testing support.
Difference Between Django and Flask
Django is better for larger projects with more features, while Flask, being a micro-framework, is suitable for smaller applications. Django provides more out-of-the-box functionality, whereas Flask offers more control and flexibility.
Differences Between Django, Pyramid, and Flask
- Flask is a micro-framework for smaller applications.
- Django is feature-rich and suitable for larger projects.
- Pyramid is flexible, allowing developers to choose tools for their projects.
- Django includes an ORM by default; Pyramid and Flask provide more control over data storage.
- These simplifications highlight key points without diving too deep into technical details.
What are Functions in Python?
Functions in Python are blocks of organized and reusable code designed to perform specific tasks. They enhance modularity and reusability in code. Python supports both built-in functions like print() and user-defined functions.
What are Attributes in Python?
In Python, class attributes (variables) have three access modifiers:
- Public: Accessible everywhere, inside or outside the class.
- Private: Accessible only within the current class.
- Protected: Accessible only within the current package.
- Attributes can also be classified as local (defined within a method), global (defined outside a method), and follow these access rules.
What is MVC Architecture?
Django follows an MVC (Model-View-Controller) architecture:
- Model: Represents the logical data structure, typically a relational database like MySQL or PostgreSQL.
- View: The user interface presented in HTML/CSS/Javascript files.
- Controller: Links the view and model, responsible for data transfer between them.
- Django applications revolve around the MVC model, displaying or modifying data.
What is Dynamically Typed Language?
In a dynamically typed language like Python, type-checking occurs during execution. Variables can change types, and type errors may only be discovered at runtime. This flexibility allows for more concise code but requires careful handling of data types during development.
What is Interpreted Language?
An interpreted language, such as Python, executes code line by line without a separate compilation step. Programs run directly from the source code. Python’s interpreter checks and executes statements during runtime, enabling dynamic typing and simplifying the development process.
What is Scope in Python?
Scope defines the region where an object in Python remains relevant. There are different scopes:
- Local Scope: Objects within the current function.
- Global Scope: Objects accessible throughout the code execution.
- Module-Level Scope: Global objects in the current module.
- Outermost Scope: Built-in names accessible in the entire program.
- Namespaces uniquely identify objects within a scope, and keywords like global can sync local and global scope objects.
