/=
What makes up a Python program's namespace?
The set of all its variables and their values.
The main method of the program itself.
The defined methods of the program.
The combination of all included modules and their functions.
At the top, or root of the class hierarchy is the most abstract class. What is the name of this class?
Object
Root
ParentClass
Main
What type of processing occurs when processes run for a slice of time, then yield access to the CPU to another process, cycling through processes repeatedly?
Cooperative processing
Divisive processing
Coalescent processing
Concurrent processing
How could you overload the addition operator in the Python language?
You create a new class with the same name as the arithmetic class, and define the __add__ method.
You create a Python script named __add__.py, and then define the new method in that script, then import it.
You create a def statement with an asterisk, then specify math.__add__ as the method name.
You declare a new method with the same name, __add__, and define the method.
In a case of infinite recursion, the Python virtual machine eventually runs out of memory resources to manage the process, so it halts execution with an error message.
True
False
What concept within object-oriented programming involves the restriction of the manipulation of an object's state by external users to a set of method calls?
Inheritance
Data encapsulation
Polymorphism
Data modeling
To get a better understanding of how recursion works, it is helpful to trace its calls.
True
False
In what higher-order function do you apply a predicate to each value within a list, and if the predicate returns true, the value is added to an object?
Mapping
Reducing
Filtering
Associating
The Python interpreter picks out equality from the other comparisons by looking for an __equals__ method when it encounters the == and != operators.
True
False
A program's namespace is the set of its variables and their values.
True
False
A list is a sequence of data values known by either of what two terms? (Choose two.)
Cards
Items
Instances
Elements
What must be done in order to concatenate a string and a float object?
The float object must be converted to a string object via the str() function.
Nothing can be done, as the two data types cannot be converted to a compatible type.
The float object must be converted to an integer object via the int() function.
The string object must be converted to a float object via the float() function.
What is the __str__ method used for?
It builds and returns a string representation of an object's state.
It is used to initiate string values during instantiation.
It converts a string attribute within a class.
It is used to determine if a class attribute is a string.
Inheritance allows several different classes to use the same general method names.
True
False
