The ____ module in Python provides a way to measure the approximate CPU time used by a process.
- cpu
- os
- sys
- time
The time module in Python provides functions for working with time, including measuring the approximate CPU time used by a process using functions like time.process_time().
The ____ sort algorithm repeatedly divides the list into two halves until each sub-list contains a single element.
- Bubble
- Insertion
- Merge
- Quick
The Merge Sort algorithm repeatedly divides the list into two halves until each sub-list contains a single element and then merges them back together in a sorted manner. It is known for its stable and efficient sorting.
The ____ statement in Python is used to verify if a given logical expression is true and raise an error if it’s false.
- assert
- check
- confirm
- validate
In Python, the assert statement is used for debugging and testing. It checks whether a given logical expression is true and raises an AssertionError if it's false, helping to catch bugs early.
The ____ statement is used to bring in an entire module into the current namespace.
- from module import *
- import all
- import module
- module import
In Python, you can use the from module import * statement to bring in all definitions from a module into the current namespace. However, it is generally recommended to use import module or from module import name to import specific functions or classes from a module.
The ____ method in TensorFlow or PyTorch is used to apply gradients to variables.
- apply_gradients
- backpropagate
- compute_gradients
- optimize
In TensorFlow and PyTorch, the apply_gradients method is used to apply gradients to variables. Gradients represent the direction and magnitude of changes needed to optimize a model's parameters during training. The apply_gradients method is an essential step in the optimization process.
The ____ method in the unittest framework is used to clean up the resources used during the test.
- cleanup
- finalize
- setUp
- tearDown
In the unittest framework, the tearDown method is used to clean up any resources or perform cleanup tasks after a test has been executed. It is often used to release resources like file handles, database connections, or temporary files created during the test.
The ____ function in the functools module is used to transform a method into a class method decorator.
- classmethod
- decorator
- method2class
- staticmethod
The classmethod function in the functools module is used to transform a method into a class method decorator. Class methods can be called on the class itself rather than on instances of the class.
The ____ keyword in Python is used to define conditions under which a block of code will be executed.
- if
- switch
- try
- while
In Python, the 'if' keyword is used to define conditions for conditional execution of code blocks. Code within an 'if' block is executed only if the specified condition evaluates to true.
The ____ method in a metaclass is called when a new object is created from a class.
- __del__
- __init__
- __new__
- __str__
The __new__ method in a metaclass is called when a new object is created from a class. This method is responsible for creating and returning a new instance of the class.
The ____ method in generator objects is used to resume the generator and send a value back to it.
- next
- resume
- send
- yield
The send method is used to resume a generator and send a value back to it. This is commonly used for implementing two-way communication with a generator.
