Python Institute PCPP1 - Certified Professional in Python Programming 1 Sample Questions (Q43-Q48):

NEW QUESTION # 43
Look at the following examples of comments and docstrings in PythonSelect the ones that are useful and compliant with PEP 8 recommendations (Select the two best answers.) A)

Answer: B,D

Explanation:
Explanation
According to PEP 8 recommendations, the two best options are Option B and Option D.
Option B follows PEP 8's suggestion that all lines should be limited to 79 characters and for longer blocks of text like docstrings or comments, the length should be limited to 72 characters1. Option D follows PEP 8's conventions for writing good documentation strings (a.k.a. "docstrings") which are immortalized in PEP
257. It suggests writing docstrings for all public modules, functions, classes, and methods2.

NEW QUESTION # 44
In the JSON processing context, the term serialization:

A. names a process in which a JSON string is turned into Python data.
B. names a process in which Python data is turned into a JSON string.
C. names a process in which a JSON string is remodeled and transformed into a new JSON string
D. refers to nothing, because there is no such thing as JSON serialization.

Answer: B

Explanation:
Explanation
In the JSON processing context, the term serialization: A. names a process in which Python data is turned into a JSON string.
Serialization refers to the process of converting a data object, such as a Python object, into a format that can be easily transferred over a network or stored in a file. In the case of JSON, serialization refers to converting Python data into a string representation using the JSON format. This string can be sent over a network or stored as a file, and later deserialized back into the original Python data object.

NEW QUESTION # 45
In the JSON processing context, the term serialization:

A. names a process in which a JSON string is turned into Python data.
B. names a process in which Python data is turned into a JSON string.
C. names a process in which a JSON string is remodeled and transformed into a new JSON string
D. refers to nothing, because there is no such thing as JSON serialization.

Answer: B

Explanation:
In the JSON processing context, the term serialization: A. names a process in which Python data is turned into a JSON string.
Serialization refers to the process of converting a data object, such as a Python object, into a format that can be easily transferred over a network or stored in a file. In the case of JSON, serialization refers to converting Python data into a string representation using the JSON format. This string can be sent over a network or stored as a file, and later deserialized back into the original Python data object.

NEW QUESTION # 46
What is true about the constructor's argument, which sets the button's title to a desired string?

A. It is the third argument of the constructor.
B. It is a keyword argument named text.
C. It is a keyword argument named title.
D. It is the second argument of the constructor.

Answer: B

Explanation:
The correct answer is D. In Tkinter, the text displayed on a Button widget is normally configured with the keyword argument text. For example, Button(root, text="OK") creates a button whose visible caption is OK. This value is not determined by the second or third positional argument in a reliable, recommended way. Tkinter widget constructors are designed to receive the parent widget first and then configuration options as keyword arguments. The keyword title is not the standard option for button captions; titles are associated more with windows, such as setting a top-level window title. For a button' s label, the correct constructor argument is text.

NEW QUESTION # 47
Select the true statements related to PEP 8 naming conventions. (Select two answers.)

A. You should always use self as the first argument to instance methods, and cls as the first argument to class methods.
B. Constants should be written in all lower-case letters with words separated by underscores
C. Function and variable names should be lower-case with words separated by underscores.
D. Modules should have short names written in CameICase.

Answer: B,C

Explanation:
Explanation
Option A is true because PEP 8 recommends that function and variable names should be lowercase, with words separated by underscores .
Option D is true because PEP 8 recommends that constants should be written in all capital letters with words separated by underscores .
PEP 8 is the official style guide for Python code. It provides guidelines for how to write readable code that follows consistent naming conventions. The aim of PEP 8 is to improve the readability of Python code and make it easier to understand and maintain.
According to PEP 8, variable and function names should be written in all lower-case letters with words separated by underscores, as stated in A. Constants, which are variables whose value is expected to remain constant throughout the code, should be written in all upper-case letters with words separated by underscores, as stated in D.
