When Python interpreter runs a script what is the script translated into?
An interpreter is a kind of program that executes other programs. When you write Python programs , it converts source code written by the developer into intermediate language which is again translated into the native language / machine language that is executed.
What statement accurately describes what a mutator is in the Python language quizlet?
What statement accurately describes what a mutator is in the Python language? A mutator is a method that is devoted entirely to the modification of the internal state of an object.
What statement accurately describes the use of a parameter in Python quizlet?
What statement accurately describes the use of a parameter in Python? A parameter is the name used in the function definition for an argument that is passed to the function when it is called.
What makes up a Python program’s namespace quizlet?
What makes up a Python program’s namespace? The set of all its variables and their values. 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?
When a Python script is running as a standalone program what will the __ name __ variable be set to?
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__“. A list is a sequence of data values known by either of what two terms? (Choose two.)
What are local variables and global variables in Python?
Global variables are those which are not defined inside any function and have a global scope whereas local variables are those which are defined inside a function and its scope is limited to that function only.
What are the two different types of loops that are used within the Python language choose two?
There are two types of loops — those that repeat an action a predefined number of times(definite iteration) and those that perform the action until the program determines that it needs to stop (indefinite iteration).
Which of the following is not a valid name that can be used for a variable?
Which of the following is not a valid variable name declaration? Explanation: Variable name cannot start with a digit. 5.
What two items are included in the class header of a class defined in Python choose two?
What two items are included in the class header of a class defined in Python? The list of one or more parent classes. The class name.
What is the __ str __ method used for?
The __str__ method in Python represents the class objects as a string – it can be used for classes. The __str__ method should be defined in a way that is easy to read and outputs all the members of the class. This method is also used as a debugging tool when the members of a class need to be checked.
When executing the print statement Python first displays the value and then evaluates the expression?
When executing the print statement, Python first displays the value and then evaluates the expression. When writing Python programs, you should use a . pyt extension. THe interpreter reads a Python expression or statement, also called the source code, and verifies that it is well formed.
What is the return value for a function that has no return statement defined Python?
So, if you don’t explicitly use a return value in a return statement, or if you totally omit the return statement, then Python will implicitly return a default value for you. That default return value will always be None .
What makes up a Python programs namespace?
Namespaces in Python. A namespace is a collection of currently defined symbolic names along with information about the object that each name references. You can think of a namespace as a dictionary in which the keys are the object names and the values are the objects themselves.
How do you create a new variable in Python?
To summarize: Python lets you create variables simply by assigning a value to the variable, without the need to declare the variable upfront. The value assigned to a variable determines the variable type. Different types may support some operations which others don’t.
What type of error is raised when the Python virtual machine runs out of memory resources to manage a process group of answer choices?
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.
What is __ name ___ in Python?
The __name__ variable (two underscores before and after) is a special Python variable. It gets its value depending on how we execute the containing script. Sometimes you write a script with functions that might be useful in other scripts as well. In Python, you can import that script as a module in another script.
What does __ main __ mean in Python?
In Python, the special name __main__ is used for two important constructs: the name of the top-level environment of the program, which can be checked using the __name__ == ‘__main__’ expression; and. the __main__.py file in Python packages.
What __ __ means in Python?
The use of double underscore ( __ ) in front of a name (specifically a method name) is not a convention; it has a specific meaning to the interpreter. Python mangles these names and it is used to avoid name clashes with names defined by subclasses.
What is the global variable in Python?
Variables that are created outside of a function (as in all of the examples above) are known as global variables. Global variables can be used by everyone, both inside of functions and outside.
What is local variable and global variable?
A global variable is a variable that is accessible globally. A local variable is one that is only accessible to the current scope, such as temporary variables used in a single function definition.
