Which HTTP method is commonly used to read or retrieve data in a RESTful API?
- DELETE
- GET
- POST
- PUT
The HTTP method commonly used to read or retrieve data in a RESTful API is GET. It is used to fetch information from a specified resource. Other methods (POST, PUT, DELETE) are typically used for creating, updating, and deleting resources.
Which keyword is used to create a class in Python?
- class
- cls
- def
- object
In Python, the keyword used to create a class is class. Classes are used to define new data types and their behaviors.
Which keyword is used to import a module in Python?
- import
- include
- module
- require
In Python, you use the import keyword to import modules. Modules are Python files containing reusable code and data.
Which library would you primarily use for implementing linear regression in Python?
- Matplotlib
- NumPy
- Pandas
- Scikit-learn
Scikit-learn is a powerful library in Python for machine learning, including linear regression. While NumPy, Pandas, and Matplotlib are essential for data manipulation and visualization, Scikit-learn provides tools for regression tasks, making it the primary choice for linear regression.
Which command is used in PDB (Python Debugger) to continue execution until the next breakpoint is encountered?
- c
- continue
- go
- next
In the Python Debugger (PDB), you can use the continue command to resume execution of your code until the next breakpoint is encountered. This allows you to step through your code and examine its behavior.
Which data structure follows the Last In First Out (LIFO) principle?
- Array
- Linked List
- Queue
- Stack
A stack is a data structure that follows the Last In First Out (LIFO) principle. It means that the last element added to the stack will be the first one to be removed. Stacks are commonly used in programming for tasks like tracking function calls and managing memory.
Which data structure in Python would you use to store a collection of unique elements?
- Dictionary
- List
- Set
- Tuple
You would use a Set in Python to store a collection of unique elements. Sets do not allow duplicate values, and they are commonly used to work with unique items. Lists (option 1) and Tuples (option 2) allow duplicate elements, and Dictionaries (option 4) store key-value pairs.
Which data structure would be the most appropriate to implement a priority queue?
- Array
- Binary Heap
- Hash Table
- Linked List
A binary heap is the most appropriate data structure to implement a priority queue because it allows efficient insertion and extraction of elements with logarithmic time complexity.
When using TensorFlow or PyTorch, the ____ method is used to load a pre-trained model.
- create_model
- import_model
- initialize_model
- load_model
When working with deep learning frameworks like TensorFlow or PyTorch, you typically use the load_model method to load a pre-trained model from a file. This allows you to reuse a model that has been previously trained on a large dataset.
When using the unittest framework, which method is executed before each test method is run?
- beforeTest()
- init()
- setUp()
- setUpClass()
In the unittest framework, the setUp() method is executed before each test method is run. This method is used to set up any preconditions or resources needed for the test.
