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 loop is most appropriate when the number of iterations is known beforehand?
- do-while
- for
- foreach
- while
The 'for' loop is most appropriate when the number of iterations is known beforehand. It is often used to iterate over a sequence or a range of values.
Which control structure allows the checking of multiple expressions for truth value and executing a block of code as soon as one of the conditions evaluates to true?
- for loop
- if-elif-else
- switch-case
- while loop
The if-elif-else control structure allows the checking of multiple expressions for truth value. It executes the block of code associated with the first true condition and then exits the structure.
Which Python library is typically used for parsing and generating JSON data?
- json
- jsondata
- jsonlib
- pyjson
The json library in Python is typically used for parsing and generating JSON (JavaScript Object Notation) data. JSON is a widely used data interchange format in web development and data processing.
You're setting up a new development environment and need multiple versions of Python. Which tool would be most suitable for managing multiple Python versions?
- Anaconda
- PyEnv
- Python Version Manager (PVM)
- Virtual Environment
PyEnv is a tool specifically designed for managing multiple versions of Python. It allows you to easily switch between different Python versions within your development environment. Virtual environments are used for isolating dependencies but not for managing different Python versions. Anaconda is a distribution of Python but doesn't focus solely on managing versions. PVM is not a commonly used tool.
One primary use case of tuples in Python programming is for _______ of multiple values.
- Indexing
- Iterating
- Packing
- Sorting
Tuples are often used for packing multiple values into a single entity, making it useful for tasks like returning multiple values from a function.
Which statement is used to create an infinite loop in Python intentionally?
- break
- for i in range(10):
- if condition:
- while True:
To create an intentional infinite loop in Python, you can use the while True: statement. It will continue to execute the code block indefinitely until explicitly interrupted.
If a class has the slots attribute defined, it means the instances of that class will not have a _______ dictionary.
- attributes
- dict
- namespace
- slots
If a class has the slots attribute defined, it means the instances of that class will not have a 'dict' dictionary. The 'slots' attribute restricts the instance to only store attributes explicitly listed in 'slots'.
To get a deep copy of nested lists, the copy module provides the _______ method.
- copy.deep()
- copy.deep_copy()
- copy.deepcopy()
- copy.nested_copy()
To create a deep copy of nested lists in Python, you can use the copy.deepcopy() method from the copy module. It ensures that nested structures are fully duplicated, avoiding any shared references.
