QUESTION: 5

Analyze the following function and choose the statement that best describes it.

It is an example of a decorator that accepts its own arguments.
It is an example of decorator stacking.
It is an example of a decorator that can trigger an infinite recursion.
The function is erroneous.

Answer(s): A

Explanation:

In the given code snippet, the repeat function is a decorator that takes an argument num_times specifying the number of times the decorated function should be called. The repeat function returns an inner function wrapper_repeat that takes a function func as an argument and returns another inner function wrapper that calls func num_times times. The provided code snippet represents an example of a decorator that accepts its own arguments. The @decorator_function syntax is used to apply the decorator_function to the some_function function. The decorator_function takes an argument arg1 and defines an inner function wrapper_function that takes the original function func as its argument. The wrapper_function then returns the result of calling func, along with the arg1 argument passed to the decorator_function.
Here is an example of how to use this decorator with some_function:

@decorator_function("argument 1")
def some_function():
return "Hello world"
When some_function is called, it will first be passed as an argument to the decorator_function. The decorator_function then adds the string "argument 1" to the result of calling some_function() and returns the resulting string. In this case, the final output would be "Hello world argument 1".

QUESTION: 6

Analyze the following snippet and select the statement that best describes it.

The code is syntactically correct despite the fact that the names of the function parameters do not follow the naming convention
The *arg parameter holds a list of unnamed parameters
The code is missing a placeholder for unnamed parameters.
The code is syntactically incorrect - the function should be defined as def f1 (*args, **kwargs)

Answer(s): B

Explanation:

The provided code snippet defines a function f1 that accepts variable-length arguments using the *args and **kwargs syntax. The *args parameter allows for an arbitrary number of unnamed arguments to be passed to the function as a tuple, while the **kwargs parameter allows for an arbitrary number of named arguments to be passed to the function as a dictionary. Therefore, the correct statement that best describes the code is:
The *args parameter holds a list of unnamed parameters, while the **kwargs parameter holds a dictionary of named parameters.

Reference:

The arg parameter holds a list of unnamed parameters. In the given code snippet, the f1 function takes two arguments: *arg and **kwarg. The *arg syntax in the function signature is used to pass a variable number of non-keyword (positional) arguments to the function. Inside the function, arg is a tuple containing the positional arguments passed to the function. The **kwarg syntax in the function signature is used to pass a variable number of keyword arguments to the function. Inside the function, kwarg is a dictionary containing the keyword arguments passed to the function.

QUESTION: 7

Analyze the following snippet and decide whether the code is correct and/or which method should be distinguished as a class method.

There is only one initializer, so there is no need for a class method.
The getNumberofCrosswords () method should be decorated With @classmethod.
The code is erroneous.
The gexNumberOfcrosswords () and issrived methods should be decorated with @classzoechod.

Answer(s): B

Explanation:

The correct answer is B. The getNumberofCrosswords() method should be decorated with @classmethod. In the given code snippet, the getNumberofCrosswords method is intended to be a class method that returns the value of the numberofcrosswords class variable. However, the method is not decorated with the @classmethod decorator and does not take a cls parameter representing the class itself. To make getNumberofCrosswords a proper class method, it should be decorated with @classmethod and take a cls parameter as its first argument. B. The getNumberofCrosswords() method should be decorated with @classmethod. This is because the getNumberofCrosswords() method is intended to access the class-level variable numberofcrosswords, but it is defined as an instance method, which requires an instance of the class to be created before it can be called. To make it work as a class-level method, you can define it as a class method by adding the @classmethod decorator to the function. Here's an example of how to define getNumberofCrosswords() as a class method:
class Crossword:
numberofcrosswords = 0

def __init__(self, author, title):
self.author = author
self.title = title
Crossword.numberofcrosswords += 1

@classmethod
def getNumberofCrosswords(cls):
return cls.numberofcrosswords
In this example, getNumberofCrosswords() is defined as a class method using the

@classmethod decorator, and the cls parameter is used to access the class-level variable numberofcrosswords.

QUESTION: 8

Analyze the code and choose the best statement that describes it.

___ne___() is not a built-in special method
The code is erroneous
The code is responsible for the support of the negation operator e.g. a = - a.
The code is responsible for the support of the inequality operator i.e. i =

Answer(s): D

Explanation:

The correct answer is D. The code is responsible for the support of the inequality operator i.e. i != j.

In the given code snippet, the __ne__ method is a special method that overrides the behavior of the inequality operator != for instances of the MyClass class.
When the inequality operator is used to compare two instances of MyClass, the __ne__ method is called to determine whether the two instances are unequal.
