In RESTful API development, what does the acronym CRUD stand for?
- Call, Retrieve, Update, Destroy
- Connect, Read, Update, Disconnect
- Copy, Read, Update, Delete
- Create, Retrieve, Update, Delete
In RESTful API development, the acronym CRUD stands for Create, Retrieve, Update, Delete. These are the four basic operations that can be performed on resources in a RESTful API.
In Python’s unittest framework, the ____ method is used to compare whether two values are equal.
- assertEqual()
- compare()
- equal()
- equalTo()
In Python's unittest framework, the assertEqual() method is used to compare whether two values are equal. It is an essential method for writing test cases to ensure expected and actual values match.
In Python, which keyword is used to define a metaclass within a class definition?
- classfor
- classmeta
- metaclass
- metaclassof
To define a metaclass within a class definition in Python, you use the keyword metaclass. This keyword specifies the metaclass for the class, allowing you to customize how the class is created and behaves.
In Python, the ____ statement is used to interrupt loop iteration and jump to the next iteration of the loop.
- break
- continue
- pass
- return
In Python, the 'break' statement is used to interrupt loop iteration and exit the loop prematurely. When 'break' is encountered inside a loop, it jumps to the next statement after the loop.
In Python, the ____ statement can be used to assert that a certain expression is true, typically used for debugging purposes.
- assert
- debug
- validate
- verify
The assert statement in Python is used to check whether a given expression is true. If the expression is false, it raises an AssertionError exception, which is helpful for debugging and ensuring that assumptions in your code hold true.
In Python, the ____ method of a unittest TestCase is run before each test method is executed.
- init
- setUp
- start
- tearDown
In Python's unittest framework, the setUp method is executed before each test method. It is typically used to set up any preconditions or resources needed for the tests.
In Python, the ____ method is used to initialize the object’s attributes when an object is created.
- create()
- init()
- new()
- object()
In Python, the __init__() method is a special method (constructor) used to initialize the object's attributes when an object is created from a class. It allows you to set up the initial state of the object.
In Python, the ____ method is used to get the number of elements in a set.
- count()
- len()
- length()
- size()
In Python, the len() function is used to get the number of elements in various data structures, including sets. It returns the length or size of the set.
In Python, the ____ keyword is used to define a generator function.
- def
- gen
- generator
- yield
In Python, the yield keyword is used to define a generator function. A generator function produces a sequence of values using the yield statement and can be paused and resumed during execution, allowing for efficient iteration over large data sets.
In Python, strings are ____, meaning they cannot be changed after they are created.
- constant
- dynamic
- immutable
- mutable
In Python, strings are immutable, which means their content cannot be changed after they are created. If you want to modify a string, you create a new one. This immutability is a fundamental characteristic of Python strings.
In Python, if you don’t specify a metaclass for a new class, it will implicitly use ____ as its metaclass.
- base
- metaclass
- object
- type
In Python, if you don't specify a metaclass for a new class, it will implicitly use type as its metaclass. type is the default metaclass for all classes unless otherwise specified.
In Python, how do you define a method inside a class to access and modify the objects’ attributes?
- def method(self):
- function method():
- method = def():
- self.method = function():
In Python, to define a method inside a class that can access and modify object attributes, you use the def method(self): syntax. The self parameter allows you to access and manipulate the object's attributes within the method.
