At ValidExamDumps, we consistently monitor updates to the Python Institute PCPP-32-101 exam questions by Python Institute. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Python Institute PCPP1 - Certified Professional in Python Programming 1 exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Python Institute in their Python Institute PCPP-32-101 exam. These outdated questions lead to customers failing their Python Institute PCPP1 - Certified Professional in Python Programming 1 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Python Institute PCPP-32-101 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
What is true about type in the object-oriented programming sense?
In Python,typeis 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 likeintandstr, are instances of thetypemetaclass and inherit from it.
Analyze the following snippet and decide whether the code is correct and/or which method should be distinguished as a class method.
The correct answer isB. The getNumberofCrosswords() method should be decorated with @classmethod. In the given code snippet, thegetNumberofCrosswordsmethod is intended to be a class method that returns the value of thenumberofcrosswordsclass variable. However, the method is not decorated with the@classmethoddecorator and does not take aclsparameter representing the class itself. To makegetNumberofCrosswordsa proper class method, it should be decorated with@classmethodand take aclsparameter as its first argument.
1. ThegetNumberofCrosswords()method should be decorated with@classmethod.
This is because thegetNumberofCrosswords()method is intended to access the class-level variablenumberofcrosswords, 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@classmethoddecorator to the function.
Here's an example of how to definegetNumberofCrosswords()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@classmethoddecorator, and theclsparameter is used to access the class-level variablenumberofcrosswords.

The following snippet represents one of the OOP pillars Which one is that?
The given code snippet demonstrates the concept of encapsulation in object-oriented programming. Encapsulation refers to the practice of keeping the internal state and behavior of an object hidden from the outside world and providing a public interface for interacting with the object. In the given code snippet, the__init__andget_balancemethods provide a public interface for interacting with instances of theBankAccountclass, while the__balanceattribute is kept hidden from the outside world by using a double underscore prefix.
What is true about the invocation of the cget () method?
The cget() method in Python is used to read the configuration options of a widget in Tkinter. It retrieves the value of a specified configuration option for a Tkinter widget. Hence, option A is the correct answer.
If w is a correctly created main application window, which method would you use to foe both of the main window's dimensions?
1. w.resizable()
Theresizable()method takes two Boolean arguments,widthandheight, that specify whether the main window can be resized in the corresponding directions. PassingFalseto both arguments makes the main window non-resizable, whereas passingTrueto 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()

Other methods that can be used to control the window size are:
w.pack_propagate () and w.grid_propagate (): These methods allow you to enable or disable the propagation of the size of the widgets inside the window to the window itself. By default, these methods are set to True, which means that the window will adjust its size according to the widgets it contains. You can set these methods to False or 0 to prevent this behavior, such as w.pack_propagate (0) or w.grid_propagate (0).
w.place (): This method allows you to place the window at a specific position and size relative to its parent window or screen. You can use keyword arguments such as x, y, width, height, relx, rely, relwidth, and relheight to specify the coordinates and dimensions of the window in absolute or relative terms, such as w.place (x=0, y=0, relwidth=1, relheight=1).
