Python Institute PCPP1 - Certified Professional in Python Programming 1 Sample Questions (Q12-Q17):

NEW QUESTION # 12
Analyze the following snippet and select the statement that best describes it.

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

Answer: C

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 # 13
Analyze the following snippet and select the statement that best describes it.

A. The *arg parameter holds a list of unnamed parameters
B. The code is syntactically incorrect - the function should be defined as def f1 (*args, **kwargs) :
C. The code is missing a placeholder for unnamed parameters.
D. The code is syntactically correct despite the fact that the names of the function parameters do not follow the naming convention

Answer: A

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:
B). The *args parameter holds a list of unnamed parameters, while the **kwargs parameter holds a dictionary of named parameters.
Reference:
Official Python documentation on Function definitions: https://docs.python.org/3/tutorial/controlflow.
html#defining-functions
The arg parameter holds a list of unnamed parameters . In the given code snippet, the f1 function takes two arguments: *arg and **kwarg . The *arg syntax in the function signature is used to pass a variable number of non-keyword (positional) arguments to the function. Inside the function, arg is a tuple containing the positional arguments passed to the function. The **kwarg syntax in the function signature is used to pass a variable number of keyword arguments to the function. Inside the function, kwarg is a dictionary containing the keyword arguments passed to the function.

NEW QUESTION # 14
Select the true statements about the sqirte3 module. (Select two answers.)

A. The sqlite3 module provides an interface compliant with the DB-API 2.0.
B. The special name memory is used to create a database in RAM.
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:
Explanation
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.
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.

NEW QUESTION # 15

NEW QUESTION # 16
Select the true statements related to PEP 8 programming recommendations for code writing. (Select two answers:)

A. You should write code in a way that favors the CPython implementation over PyPy, Cython. and Jython.
B. You should not write string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them
C. You should make object type comparisons using the ismstanceQ method (e.g. if isinstance (obj, int) :) instead of comparing types directly (eg if type(obj) is type(i)).
D. You should use the not ... is operator (e.g. if not spam is None:), rather than the is not operator (e.g. if spam is not None:), to increase readability.

Answer: B,C

Explanation:
The two true statements related to PEP 8 programming recommendations for code writing are Option B and Option D .
Option B is true because PEP 8 recommends making object type comparisons using the isinstance() method instead of comparing types directly 1 .
Option D is true because PEP 8 recommends not writing string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them 1 .
