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

NEW QUESTION # 26
Select the true statements about the sqlite3 module. (Select two answers.)

A. The execute method allows you to perform several queries at once
B. The fetchalt method returns None when no rows are available
C. The fetchone method returns None when no rows are available
D. The execute method is provided by the Cursor class

Answer: C,D

Explanation:
C). The execute method is provided by the Cursor class
This statement is true because the execute method is one of the methods of the Cursor class in the sqlite3 module. The Cursor class represents an object that can execute SQL statements and fetch results from a database connection. The execute method takes an SQL query as an argument and executes it against the database. For example, cur = conn.cursor (); cur.execute ("SELECT * FROM table") creates and executes a cursor object that selects all rows from a table.
D). The fetchone method returns None when no rows are available
This statement is true because the fetchone method is another method of the Cursor class in the sqlite3 module. The fetchone method fetches the next row of a query result set and returns it as a single tuple or None if no more rows are available. For example, row = cur.fetchone () fetches and returns one row from the cursor object or None if there are no more rows.

NEW QUESTION # 27
Select the true statements about PEP 8 recommendations related to using blank lines. (Select two answers.)

A. You should surround top-level functions and class definitions with one blank line.
B. You should surround top-level functions and class definitions with two blank lines.
C. You should not put any blank lines between groups of imports.
D. You should surround method definitions inside classes by a single blank line.

Answer: B,D

Explanation:
The correct answers are C and D. PEP 8 recommends surrounding top-level function and class definitions with two blank lines. This improves readability by clearly separating major program units in a module. Inside a class, method definitions should be separated by a single blank line because methods are more closely related and need less visual separation than top-level definitions. Option A is incorrect because imports are commonly grouped into standard library imports, third-party imports, and local application imports, with blank lines separating those groups. Option B is incorrect because one blank line is insufficient for top-level functions and classes under PEP 8. These spacing rules support clean, predictable, maintainable Python code layout.

NEW QUESTION # 28
Which of the following methods allow you to load a configuration using ConfigParser? (Select two answers.)

A. read_conf
B. read_dict
C. read
D. read_str

Answer: C,D

Explanation:
Explanation
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.

NEW QUESTION # 29
Look at the following examples of comments and docstrings in PythonSelect the ones that are useful and compliant with PEP 8 recommendations (Select the two best answers.) A)

Answer: A,D

Explanation:
Explanation
According to PEP 8 recommendations, the two best options are Option B and Option D.
Option B follows PEP 8's suggestion that all lines should be limited to 79 characters and for longer blocks of text like docstrings or comments, the length should be limited to 72 characters1. Option D follows PEP 8's conventions for writing good documentation strings (a.k.a. "docstrings") which are immortalized in PEP
257. It suggests writing docstrings for all public modules, functions, classes, and methods2.

NEW QUESTION # 30
Look at the following examples of comments and docstrings in Python. Select the ones that are useful and compliant with PEP 8 recommendations. (Select the two best answers.)

A. val = val + 1.15 # Compensate for diminished value.
B. n = n - 1 # Decrement n by 1.
C. def total_cost(q):
'''Takes the q argument and multiplies it by 1.15.'''
return q * 1.15
D. def net_expense(q, price):
"""Return the total cost of items before tax."""
return q * price

Answer: A,D

Explanation:
The correct answers are A and C. Option A uses a concise one-line docstring that explains the function' s purpose in a useful way. It follows the common Python documentation style by describing what the function returns rather than repeating implementation mechanics. Option C is also useful because the inline comment explains why the value is being adjusted, not merely what the code already shows.
Option B is poor because it restates the obvious operation n = n - 1; such comments add noise instead of clarity. Option D is weaker because the docstring describes internal mechanics and argument handling rather than the function's intended result. Good Python comments should clarify intent, purpose, or non-obvious reasoning.
