Top Python Full stack Developer Interview Questions
Python Back-End Development Questions
Q. Describe Python Global Interpreter Lock (GIL).
Answer: A GIL is a mutex that protects access to Python objects, preventing multiple threads from executing Python bytecode at once. This ensures thread safety but can cause bottlenecks in CPU-bound programs.
Q. What are Python decorators and how do you use them?
Answer: Decorators are functions that modify the functions of other functions. It is used to extend its behavior through the @decorator_name syntax above the function definition.
Q. How does Python handle packages and dependencies in projects?
Answer: Packages and dependencies are managed with tools like pip and virtualenv or pipenv. requirements.txt file or used to list Pipfile dependencies.
Q. Explain the Django MVC framework.
Answer: Django follows an MTV (Model-Template-View) framework similar to MVC. This models represent the data structures, the templates are the user interface. And Views handle the logic and interactions between the models and templates.
Q. How do you optimize a Django application to run?
Answer: Make a good use of database indexing and aslo use tools like Redis or Memcached caching. Use the Django select_related and prefetch_related for the optimized queries, and then use efficient middleware.
Python Front-end Development Questions
Q. What is the difference between CSS Flexbox and the Grid layout?
Answer: The Flexbox is one-dimensional organizing objects into rows or columns. And the Grid layout is two-dimensional and it will allowing for rows and columns.
Q. Explain the concept of Virtual DOM in the React?
Answer: The virtual DOM is a small JavaScript representation of the real DOM. And React differences the virtual DOM with a snapshot of the previous state and then uses it to modify the updates only by applying the necessary changes to the real DOM.
Q. What is the main difference between let, const, and var in the JavaScript?
Answer: The var is function-scoped and can be redeclared. The let and const functions are block-scoped. let can be returned, while const cannot be returned after the declaration.
Q. How is a state management handled in React?
Answer: The React’s built-in useState and useReducer hooks can be used to handle complex states. By using the external libraries such as Redux, MobX, or the Context API.
Q. What are the Web Components and why are they useful?
Answer: The Web Components are web platform APIs that will allow you to create embedded custom and the reusable HTML tags from the rest of the code. They are useful for producing modular, maintainable, and the reusable components.
Full stack Integration Questions
Q. How are authentication and the authorization handled in a full-stack application?
Answer: Use libraries like Django Auth for the back-end authentication. The JWT tokens for stateless sessions, and the middleware for access security. Also use OAuth for third-party authentication services.
Q. Explain the role of RESTful APIs in a full-stack application?
Answer: The RESTful APIs enable communication between frontend and backend by exposing the endpoints that can be reached using the HTTP methods. Also they provide a customized way to communicate with the server.
Q. What are the some common security vulnerabilities in the web applications, and how do you fix them?
Answer: The most common types are SQL injection, XSS, CSRF, and data exposure. They prevent them by using the passwords, password authentication, password encoding, security libraries, and the HTTPS.
Q. Describe the implementation of a full-stack application.
Answer: Deployment includes setting up a server environment (e.g., using AWS, Heroku), setting up a web server (Nginx/Apache), setting up a database, and using a CI/CD pipeline for automated deployment.
Q. How data migration is handled in Django application?
Answer: Data migration in Django is managed using Django’s migration framework. Changes to the model generate a migration file, which you can use with python manage.py migrate to update the database schema.
Basic Python Full stack Developer Interview Questions
Q. What is multithreading?
Q. Explain CI (Continuous Integration)?
Q. What is event loop in Node.js?
Q. Define Restful API and its uses?
Q. What is MEAN Stack?
Q. What is dynamically typed language?
Q. What does Python scope mean?
- The local objects accessible in the current function are referred to as the local scope.
- The items that have been accessible since the beginning of code execution are referred to as the global scope.
- The global objects of the current module that are accessible within the programme are referred to as a module-level scope.
- The term “outermost scope” describes all of the program’s callable built-in names. The name mentioned is found by searching the items in this scope last.
Q. What are lists and tuples? What are the key difference between them?
Q. What is the use of self in Python?
- Python’s unit testing framework is called unit test.
- Unit testing is the process of testing individual software components.
- For this reason, it’s essential to thoroughly test every component to identify the one that may be mostly to blame for the software’s failure.
