Python Institute PCPP1 - Certified Professional in Python Programming 1 Sample Questions (Q26-Q31):

NEW QUESTION # 26
Select the true statements about the sqirte3 module. (Select two answers.)

A. The special name memory is used to create a database in RAM.
B. The sqlite3 module provides an interface compliant with the DB-API 2.0.
C. The fetchall method returns an empty list when no rows are available
D. The sqhte3 module does not support transactions.

Answer: A,B

Explanation:
A). The sqlite3 module in python provides an interface compliant to the DB-API 2.0. Thus, it follows a standard performance metric that allows for consistency in database programming with python.
B). The special name 'memory' is used to create a database in RAM using the sqlite3 module. Thus, when you use it as the name of the database file while opening a connection, it creates a temporary database that exists only in memory.
Reference: Official Python documentation on sqlite3: https://docs.python.org/3/library/sqlite3.html

NEW QUESTION # 27
Analyze the following snippet and select the statement that best describes it.

A. The code is an example of explicitly chained exceptions.
B. The code is erroneous as the OwnMath class does not inherit from any Exception type class
C. The code is fine and the script execution is not interrupted by any exception.
D. The code is an example of implicitly chained exceptions.

Answer: A

Explanation:
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.

NEW QUESTION # 28
Select the true statements about the json.loads() function.
(Select two answers.)

A. It returns a JSON string.
B. It takes Python data as its argument.
C. It takes a JSON string as its argument.
D. It returns a Python entity.

Answer: C,D

Explanation:
The correct answers are C and D. The json.loads() function is used for JSON deserialization. It accepts a JSON-formatted string, bytes, or bytearray and converts that serialized JSON data into an equivalent Python object. For example, a JSON object becomes a Python dictionary, a JSON array becomes a Python list, JSON strings become Python strings, and JSON numbers become Python numeric values.
Option A describes json.dumps(), which takes Python data and serializes it into JSON text. Option B is also incorrect because returning a JSON string is the job of json.dumps(), not json.loads(). Therefore, json.loads() takes JSON text as input and returns a Python entity.

NEW QUESTION # 29
Which methods can be invoked in order to draw a triangle?
(Select two answers.)

A. create_triangle_shape()
B. create_shape()
C. create_line()
D. create_polygon()

Answer: C,D

Explanation:
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().

NEW QUESTION # 30
What isa___traceback___?
(Select two answers )

A. A special method delivered by the traceback module to retrieve a full list of strings describing thetraceback
B. An attribute owned by every exception object
C. An attribute that is added to every object when the traceback module is imported
D. An attribute that holds interesting information that is particularly useful when the programmer wants to store exception details in other objects

Answer: B,D

Explanation:
Explanation
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.
