Free Python Institute PCPP-32-101 Exam Actual Questions
The questions for PCPP-32-101 were last updated On Nov. 19, 2023
Which of the following methods allow you to load a configuration using ConfigParser? (Select two answers.)
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.
Select the true statements about the json.-dumps () function. (Select two answers.)
The json.dumps() function is used to convert a Python object into a JSON string1. It takes Python data as its argument, such as a dictionary or a list, and returns a JSON string.
1. It returns a JSON string.
This statement is true because the json.dumps () function takes a Python object as its argument and returns a JSON-formatted string that represents the object. For example, json.dumps ([1, 2, 3]) returns '[1, 2, 3]'.
What is ElementTree?
ElementTree is a Python built-in module that provides a simple and efficient API for parsing and creating XML data. It allows you to access and manipulate XML data in a very straightforward way, making it easy to write XML processing applications.
This statement is true because ElementTree is a module in the standard library of Python that provides an API for working with XML data. The module supports parsing XML from strings or files, creating XML trees from scratch or modifying existing ones, searching and iterating over XML elements, and writing XML data to strings or files.
What is true about the unbind () method? (Select two answers.)
Option B is true because theunbind()method is invoked from within a widget's object1.
Option D is true because theunbind()method needs the event name as an argument1.
Theunbind()method in Tkinter is used to remove a binding between an event and a function. It can be invoked from within a widget's object when a binding is no longer needed. The method requires the event name as an argument to remove the binding for that specific event. For example:
button = tk.Button(root, text='Click me')
button.bind('<Button-1>', callback_function) # bind left mouse click event to callback_function
button.unbind('<Button-1>') # remove the binding for the left mouse click event
Look at the following code snippets and decide which ones follow PEP 8 recommendations for whitespaces in expressions and statements (Select two answers.)
A)
No whitespace immediately before the opening parenthesis that starts the list of arguments of a function call:
B)
A whitespace immediately before a comma, semicolon, and colon:
C)
No whitespace between a trailing comma and a following closing parenthesis:
D)
A whitespace immediately after the opening parenthesis that starts indexing or slicing:
