New Python Institute PCPP-32-101 Dumps & Questions Updated on 2026 [Q11-Q30]

The correct answers are B. Option B and D. Option D . Both options B and D are compliant with PEP 8 recommendations for line breaks and indentation. PEP 8 recommends using 4 spaces per indentation level and breaking lines before binary operators. In option B, the arguments to the print function are aligned with the opening delimiter, which is another acceptable way to format long lines according to PEP 8. In option D, the second line is indented by 4 spaces to distinguish it from the next logical line.

The correct answers are C and D. In Python’s sqlite3 module, the string ‘:memory:’ is passed to sqlite3.
connect() to create an in-memory SQLite database. This establishes a valid database connection, but the database exists only in RAM and normally disappears when the connection is closed. It is useful for testing, temporary storage, fast operations, and examples where no persistent database file is required.
Option A is wrong because :memory: does not load an existing file-based database into memory. Option B is also incorrect because it is not a deletion command or database management operation. It is simply a special database name recognized by SQLite to create a temporary in-memory database.

The correct answer is B. The ConfigParser.sections() method returns a list of section names, but it does not include the special DEFAULT section. Therefore, even though config[‘DEFAULT’] = {} is present, DEFAULT is excluded from the printed result. The code then creates three regular sections: mysql, postgresql, and redis. Assigning config[‘redis’] = config[‘postgresql’] creates or updates a separate section named redis using the values from the postgresql section; it does not duplicate the section name postgresql in the section list. Therefore, the output contains only the normal section names: [‘mysql’,
‘postgresql’, ‘redis’] .

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.

The correct answers are C and D. Custom application exceptions should normally inherit from Exception, not directly from BaseException. BaseException is intended for system-exiting exceptions such as SystemExit, KeyboardInterrupt, and GeneratorExit, so deriving ordinary errors from it can interfere with normal control flow. PEP 8 also discourages broad or bare except: clauses because they catch too much and can hide programming errors or prevent expected interruption behavior. Specific exception handling is clearer, safer, and easier to debug. Option A reverses the intended guidance:
exception hierarchies should help code distinguish what went wrong programmatically. Option B is false because a bare except: can catch system-level exceptions, which is exactly why it should be avoided.

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

The unbind_all() method in Tkinter is used to remove all event bindings from a widget. It is a method of the widget object and can be called on any widget in the Tkinter application. Therefore, option A is the correct answer.
Option B is incorrect because the method can be called on any widget, not just the main window widget.
Option C is correct as unbind_all() does not take any parameters.
Option D is incorrect because the method only removes event bindings and does not cause the widgets to disappear.
So, the correct answers are A and C.

Explanation
A socket object is usually created using the socket() constructor provided by the socket module in Python. The correct invocation is socket.socket(socket_domain, socket_type). This creates a new socket object with the specified socket domain and type.

Explanation
The socket.gaierror exception is raised when an address-related error caused by the getaddrinfo() and getnameinfo() functions occurs. These functions are used to translate hostnames to IP addresses and vice versa, and the gaierror exception is raised if they fail to perform this translation.

The correct answers are C and D. PEP 8 recommends that module names should be short and entirely lower-case; underscores may be used only when they improve readability. This keeps imports clean and predictable. PEP 8 also warns against using the single-character variable names l, O, or I because they can be visually confused with 1 and 0 in many fonts. Option A is incorrect because Python class names should normally use the CapWords convention, not mixedCase. Option B is incorrect because exception names are class names and should follow class naming conventions; if the exception represents an error, the name should usually end with Error.

Explanation
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 500×400 pixels and makes it non-resizable:
importtkinter as tk
root = tk.Tk()
root.geometry(“500×400”)
root.resizable(False, False)
root.mainloop()

The resizable () method of a tkinter window object allows you to specify whether the window can be resized by the user in the horizontal and vertical directions. You can pass two boolean arguments to this method, such as w.resizable (False, False), to prevent both dimensions from being changed. Alternatively, you can pass 0 or
1 as arguments, such as w.resizable (0, 0), to achieve the same effect1.

1: https://stackoverflow.com/questions/36575890/how-to-set-a-tkinter-window-to-a-constant-size Other methods that can be used to control the window size are:
* w.geometry () : This method allows you to set the initial size and position of the window by passing a string argument in the format “widthxheight+x+y”, such as w.geometry (“500×500+100+100”)12.
* w.minsize () and w.maxsize (): These methods allow you to set the minimum and maximum size of the window in pixels, such as w.minsize (500, 500) and w.maxsize (1000, 1000)12.
* 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).

Explanation
In the given code snippet, an instance of OwnMath exception is raised with an explicitly specified __cause__ attribute that refers to the original exception (ZeroDivisionError). This is an example of explicitly chaining exceptions in Python.

Explanation
The socket.gaierror exception is raised when an address-related error caused by the getaddrinfo() and getnameinfo() functions occurs. These functions are used to translate hostnames to IP addresses and vice versa, and the gaierror exception is raised if they fail to perform this translation.

Explanation
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.

Explanation
The correct answer is C. Excalibur is the value passed to an instance variable. In the given code snippet, self.name is an instance variable of the Sword class. When an instance of the Sword class is created with varl = Sword(‘Excalibur’), the value ‘Excalibur’ is passed as an argument to the __init__ method and assigned to the name instance variable of the varl object.
The code defines a class called Sword with an __init__ method that takes one parameter name. When a new instance of the Sword class is created with varl = Sword(‘Excalibur’), the value of the ‘Excalibur’ string is passed as an argument to the __init__ method, and assigned to the self.name instance variable of the varl object.

Explanation
According to PEP 8, Python’s official style guide, line breaks before binary operators produce more readable code, especially in code blocks with long expressions. This is stated in several sources (1,2,6,8) and is a widely accepted convention.

Explanation
A socket is a connection point that enables a two-way communication between programs running in a network.
This statement is true because a socket is a software structure that serves as an endpoint for sending and receiving data across a network. A socket is defined by an application programming interface (API) for the networking architecture, such as TCP/IP. A socket can be used to establish a communication channel between two programs running on the same or different network nodes12.
A socket is always the secure means by which computers on a network can safely communicate, without the risk of exposure to an attack.
This statement is false because a socket by itself does not provide any security or encryption for the data transmitted over the network. A socket can be vulnerable to various types of attacks, such as eavesdropping, spoofing, hijacking, or denial-of-service. To ensure secure communication, a socket can use additional protocols or mechanisms, such as SSL/TLS, SSH, VPN, or firewall3.
A socket is a connection point that enables a one-way communication only between remote processes.
This statement is false because a socket can enable both one-way and two-way communication between processes running on the same or different network nodes. A socket can be used for connection-oriented or connectionless communication, depending on the type of protocol used. For example, TCP is a connection-oriented protocol that provides reliable and bidirectional data transfer, while UDP is a connectionless protocol that provides unreliable and unidirectional data transfer12.
A socket can be used to establish a communication endpoint for processes running on the same or different machines.
This statement is true because a socket can be used for inter-process communication (IPC) within a single machine or across different machines on a network. A socket can use different types of addresses to identify the processes involved in the communication, such as IP address and port number for network sockets, or file name or path for Unix domain sockets12.

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.
