What are the two arguments expected by the get method for a dictionary object? (Choose two.)
An index position.
A possible key.
A list of keys.
A default value.
What is the purpose of a higher-order function?
It separates the task of transforming data values from the logic of accumulating the results.
It is a special function that ignores program scope and has access to localized variables.
It allows the definition of specialized ordering logic for data sets.
It is a mutator that can be utilized on functions to remove redundant patterns in code.
Inheritance allows a class to automatically reuse and extend the code of similar but more general classes.
True
False
What type of error is raised when the Python virtual machine runs out of memory resources to manage a process?
Input output error
Runaway process error
Out of memory error
Stack overflow error
What happens if you use the following statement to sort a list of numbers called numbers? numbers = numbers.sort()
The list is now ordered in descending order.
The numbers variable becomes a reference to a sorted list.
Numbers is a value of None
The list is now ordered in ascending order.
When you design an algorithm, it should be general enough to provide a solution to many problem instances, not just one or a few of them.
True
False
If you wanted to overload the greater than or equal operator, what method name should you define?
__gt__
__geq__
__ge__
__gte__
In Python, = means equals, whereas == means assignment.
True
False
To overload an arithmetic operator, you just define a new method using the appropriate method name.
True
False
When the step argument is a negative number, the range function generates a sequence of numbers from the first argument down to the second argument plus 1.
True
False
Moore's Law states that the processing speed and storage capacity of hardware will increase and its cost will decrease by approximately a factor of 3 every 18 months.
True
False
A class variable is visible to all instances of a class and does not vary from instance to instance.
True
False
When a Python script is running as a standalone program, what will the __name__ variable be set to?
The variable will be set to "__main__".
The variable will hold the name of the script itself.
The variable will be set to "None".
The variable will be set to "standalone".
A method is always called with a given data value called an object, which is placed before the method name in the call.
True
False
What statement accurately reflects the difference between the quotient operator and the division operator?
The quotient operator produces a float, while the division operator produces an integer.
The quotient operator produces an integer, while the division operator produces a float.
The two operators are effectively the same, unless being carried out on strings.
The quotient operator produces a float, while the division operator produces an integer + remainder.
