Option A is true because PEP 8 recommends avoiding extraneous whitespace immediately inside parentheses, brackets or braces  1 .

Option C is true because PEP 8 recommends avoiding extraneous whitespace between a trailing comma and a following close parenthesis  1 .

This statement is true because the code uses the logging module to create a logger object and set its level to logging.INFO. The logging module provides a way of reporting events that occur during the execution of a program. The logging level determines which events are reported and which are ignored. The logging module defines five levels of severity: DEBUG, INFO, WARNING, ERROR, and CRITICAL. The lower the level, the more events are reported.

The code then uses the logger object to log two messages: one with the level logging.DEBUG and one with the level logging.INFO. The logger object only reports the messages that have a level equal or higher than its own level. Therefore, the message with the level logging.DEBUG is ignored, while the message with the level logging.INFO is reported. The default format for reporting messages is “level name: message”. Therefore, the output of the code is:

INFO: Loading data…

If purple can be obtained from mixing red and blue, which color codes represent the two ingredients? Select two answers)

A. #FFFFFF

B. #0000FF

C. #FF0000

D. #000000

In Python,  type  is the built-in metaclass that serves as the base class for all new-style classes. All new-style classes in Python, including built-in types like  int  and  str , are instances of the  type  metaclass and inherit from it.

A static method is a method that belongs to a class rather than an instance of the class. It is defined using the  @staticmethod  decorator and does not take a  self  or  cls  parameter. Static methods are often used to define utility functions that do not depend on the state of an instance or the class itself.

The correct answers are B and C. In Python, exception objects have a __traceback__ attribute that stores traceback information connected with the point where the exception was raised. This makes option C true. The traceback object can be processed using functions from the traceback module, including traceback.format_tb(), which formats traceback entries into readable strings, so option B is also true. Option A is wrong because __traceback__ is not a special method and is not “delivered” by the traceback module; it is an exception attribute. Option D is also incorrect because the attribute is not limited only to exceptions in an explicit or implicit exception chain.

The correct answers are  A. An attribute owned by every exception object  and  D. An attribute that holds interesting information that is particularly useful when the programmer wants to store exception details in other objects . A traceback is an attribute of an exception object that contains a stack trace representing the call stack at the point where the exception was raised. The traceback attribute holds information about the sequence of function calls that led to the exception, which can be useful for debugging and error reporting.

The correct answers are B and D. In Tkinter’s Canvas widget, there is no built-in method named create_shape() or create_triangle_shape(). A triangle can be drawn either with create_line() by connecting three line segments between three coordinate points, or with create_polygon() by providing three vertices. create_polygon() is the more direct method because a triangle is a polygon with three sides, and Tkinter can render it as a filled or outlined shape. create_line() is also valid when the programmer manually draws the three sides and closes the shape. Therefore, the valid Canvas methods for producing a triangle are create_line() and create_polygon().

C. w.resizable()

The  resizable()  method takes two Boolean arguments,  width  and  height , that specify whether the main window can be resized in the corresponding directions. Passing  False  to both arguments makes the main window non-resizable, whereas passing  True  to both arguments (or omitting them) makes the window resizable.

Here is an example that sets the dimensions of the main window to 500x400 pixels and makes it non-resizable:

import tkinter as tk

root = tk. Tk ()

root. geometry ( "500x400" )

root. resizable (False, False)

root. mainloop ()
