Answer : A, D

ConfigParser is a built-in library in Python that allows you to read and write configuration files. The read method is used to read the configuration file which can be in any of the supported file formats, such as INI, YAML, and JSON. The read_dict method is used to read the configuration from a Python dictionary. The read_conf and read_str options are not valid methods in the ConfigParser module.

Therefore, the correct options to load a configuration using ConfigParser are A. read and D. read_string.

Answer : C

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()

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.

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 (''500x500+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).

Answer : A, C

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.

Answer : A, C

Option A is true because PEP 8 recommends avoiding extraneous whitespace immediately inside parentheses, brackets or braces1.

Option C is true because PEP 8 recommends avoiding extraneous whitespace between a trailing comma and a following close parenthesis1.

Answer : B

The true statement related to PEP 257 isOption B. According to PEP 257, string literals occurring elsewhere in Python code may also act as documentation. They are not recognized by the Python bytecode compiler and are not accessible as runtime object attributes (i.e. not assigned todoc), but two types of extra docstrings may be extracted by software tools: String literals occurring immediately after a simple assignment at the top level of a module, class, orinitmethod are called ''attribute docstrings''.String literals occurring immediately after another docstring are called ''additional docstrings''1.
