When you want a variable to be available both inside and outside a function, you declare it as a _______ variable.
- Global
- Instance
- Local
- Non-local
To make a variable accessible both inside and outside a function, you declare it as a 'global' variable. It has a global scope.
While iterating through data entries, you want to avoid processing entries labeled as 'SKIP.' Instead of terminating the loop upon encountering such entries, what should you use to continue to the next entry?
- break
- continue
- pass
- return
To continue to the next entry without terminating the loop, you should use the continue statement. It skips the current iteration and moves on to the next one in the loop, allowing you to bypass processing entries labeled as 'SKIP' and continue with the rest of the loop.
When using a nested loop inside a list comprehension, the _______ loop should be specified first.
- Inner
- Outer
- Primary
- Secondary
When using nested loops in list comprehensions, the inner loop should be specified first. This is because the inner loop is executed more frequently and iterates over each element in the inner sequence, while the outer loop iterates over the outer sequence. The inner loop determines how the elements are constructed in the resulting list comprehension.
You have a base class Vehicle and a derived class Car. The base class has a method start(). If you want to add additional functionalities to the start() method specifically for the Car class without affecting the base class, what should you do?
- Use method overloading to create a new start() method in the Car class
- Use method overriding to override the start() method in the Car class
- Use multiple inheritance to inherit from both Vehicle and Car classes and create a new start() method in the Car class
- Use the super() keyword to extend the start() method in the Car class
In this case, you should use method overriding in the Car class. By using the super() keyword, you can extend the functionality of the start() method specific to the Car class without modifying the base class (Vehicle) method. This approach follows the principle of object-oriented programming and avoids redundancy.
When writing nested if statements, each new condition should be indented under the ______ statement.
- elif
- else
- if
- while
When writing nested if statements in Python, each new condition should be indented under the 'if' statement to indicate it's a part of that condition's block.
Which of the following symbols is used to define a tuple in Python?
- ( )
- < >
- [ ]
- { }
In Python, tuples are defined using parentheses ( ). For example, my_tuple = (1, 2, 3) creates a tuple named my_tuple.
Which Python Enhancement Proposal (PEP) introduces the concept of "The Zen of Python"?
- PEP 20
- PEP 42
- PEP 64
- PEP 8
"The Zen of Python" is introduced in PEP 20. It encapsulates the guiding principles and philosophy of Python's design.
In Python, to create a private attribute in a class, you prefix the attribute name with _______.
- @private
- __private
- _private
- private:
In Python, a private attribute is created by prefixing the attribute name with a double underscore, like "__private".
Which Python feature allows functions to accept any number of keyword arguments?
- **args
- **arguments
- **kwargs
- *arguments
The feature in Python that allows functions to accept any number of keyword arguments is **kwargs. This is often used when you want to pass a variable number of keyword arguments to a function. The double asterisk ** before kwargs allows you to collect keyword arguments into a dictionary within the function.
You've received a JSON file with non-ASCII characters, and while reading the file using the Python json module, you're facing an encoding issue. What can be done to correctly parse the JSON?
- Convert the non-ASCII characters to their Unicode equivalents.
- Use a different JSON parsing library that supports non-ASCII characters.
- Use the 'json.load' function with the 'encoding' parameter.
- Use the 'open' function with an explicit encoding argument.
To correctly parse a JSON file with non-ASCII characters, you can use the 'open' function with an explicit encoding argument to specify the correct character encoding used in the file.
