In Django, the ____ file is used to store the settings of a project, such as database configurations.
- models
- settings
- templates
- views
In Django, the settings.py file is used to store project-level settings, including database configurations, middleware, and other global settings. It's a central configuration file for a Django project.
In Django, the ____ method is used to handle HTTP GET requests specifically in class-based views.
- fetch
- get
- obtain
- retrieve
In Django class-based views, the get method is used to handle HTTP GET requests. This method is called when a user accesses a view via a GET request, allowing you to define how the view should respond to such requests.
In Django, what is the name of the file used to define the URL patterns of an app?
- links.py
- patterns.py
- routes.py
- urls.py
In Django, the file used to define URL patterns for an app is usually named urls.py. This file maps URLs to views, helping Django route incoming requests to the appropriate view functions.
In Django, what is the role of a "view"?
- Defining the database schema
- Handling HTTP requests and returning HTTP responses
- Managing user authentication
- Rendering HTML templates
In Django, a "view" is responsible for handling HTTP requests and returning HTTP responses. Views contain the application logic and decide what data to display and how to display it.
In Flask, how would you access the data sent with a POST request?
- request.args
- request.data
- request.form
- request.get_data()
In Flask, to access the data sent with a POST request, you can use request.data. This attribute contains the raw request data, which can be useful for handling various types of input data, including JSON.
In Flask, the ____ function is used to render a template and send it to the client’s browser.
- create_template
- render_template
- send_template
- template_render
In Flask, the render_template function is used to render an HTML template and send it as a response to the client's browser. This function is essential for generating dynamic web pages.
In Flask, the ____ method is used to render a template and return a response object with it.
- create_template
- load_template
- render_template
- view_template
In Flask, the render_template method is used to render an HTML template and return it as a response object. This is commonly used for generating dynamic web pages.
In algorithm analysis, ____ denotes the upper bound of the running time of an algorithm.
- Big-O
- O-notation
- Θ-notation
- Ω-notation
In algorithm analysis, Big-O notation (often represented as O-notation) denotes the upper bound of the running time of an algorithm. It provides an upper limit on how the algorithm's runtime scales with input size.
In deep learning models built using TensorFlow or PyTorch, the ____ method is used to update the model parameters based on the computed gradients.
- backward
- fit
- optimize
- predict
In deep learning frameworks like TensorFlow or PyTorch, the optimize method (or optimizer) is used to update the model parameters (weights) based on the computed gradients during training. This step is a crucial part of the training process as it helps the model learn from the data.
How would you use a mock object in Python for testing a function that makes an HTTP request?
- Create a mock object that simulates the behavior of an HTTP request, allowing you to test the function's behavior without making actual network requests.
- Modify the function to skip the HTTP request when testing, replacing it with a placeholder function.
- Use a third-party library like httpretty to intercept and mock HTTP requests within the function.
- Use the built-in unittest.mock library to automatically mock HTTP requests made by the function.
To test a function making HTTP requests, creating a mock object that simulates HTTP behavior is a common practice. This ensures that tests are isolated and don't depend on external services.
