A variable is named and also assigned a value or expression. If multiple values are assigned to the same named variable, the last assignment is the one used. = Correct Answer- assignment operator, assigns a value == Correct Answer- a comparison operator used to compare if one operator is equal to another > Correct Answer- a comparison operator used to compare if one operator is greater than another >= Correct Answer- a comparison operator used to compare if one operator is greater than or equal to another A = True / B = False: not (A and B) Correct Answer- Answer: not (True and False) = not (False) = True A = True / B = False: not (A or B) Correct Answer- Answer: not (True or False) = not (True) = False A = True / B = False: not A and not B Correct Answer- Answer: not True and not False = False A = True / B = False: not A or not B Correct Answer- Answer: not True or not False = True A biologist wants to process water salinity measurement until water temperature falls below a certain level. Which control structure supports this biologist's needs? Correct Answer- While loop abstraction Correct Answer- Focus on the essential qualities of something rather than one specific example.Activity Correct Answer- The actions required to achieve or abandon a goal Actor Correct Answer- A person or entity that interacts with a system actors Correct Answer- An Actor in a use case is anything with behavior who lives outside of your system, outside of your application, but has a goal they want to accomplish within. Addition Operator (Also Concatenates Strings) Correct Answer- + algorithm Correct Answer- A set of commands that returns a value. This differs from a procedure, which is a set of commands that doesn't necessarily have to return a value. append() Correct Answer- Mutates <List> by adding <Element> to the end of the list. argument Correct Answer- The inputs to a procedure. Also called operands. Assignment Operator (Assigns A Value) Correct Answer- = attributes Correct Answer- Characteristics of an object which may be used to reference other objects or save object state information. base case Correct Answer- An expression that has a value and is not defined in terms of some other thing we are defining. This breaks the chain of recursion. benchmark Correct Answer- A known value of performance that can be compared against at a future time and under a specific load. Boolean Correct Answer- A value that is either True or Falsecircular definition Correct Answer- A definition that doesn't give us answers because it never finishes. It is stuck in a loop with each reference pointing to another reference. It has no base case. class <ClassName> (<BaseClass>): <Block> Correct Answer- How to define a class in Python class Correct Answer- Describes what an object will be, but it isn't the object itself. This is a blueprint for that object. class diagram (UML) Correct Answer- The most common diagram in Object-Oriented Design. Shows the system classes and relationships between them. Diagrams the primary attributes and primary operations for each class. code modularity Correct Answer- Dividing software or an application into smaller modules. This provides prewritten code which saves resources and provides greater manageability. comparison operator Correct Answer- Used to make a comparison between two values. Comparison Operator Equal To Correct Answer- == Comparison Operator Greater Than Correct Answer- > Comparison Operator Greater Than or Equal To Correct Answer- >= Comparison Operator Less Than Correct Answer- < Comparison Operator Less Than or Equal To Correct Answer- <=Comparison Operator Not Equal Correct Answer- != compiled language Correct Answer- You write source code, and compiler goes through that code and creates a separate file containing the machine code. That new file is used to run the program. Can be faster than interpreted code. Must be compiled for a specific platform. compiler Correct Answer- A program that takes source code and converts it to machine code by producing a separate file. Compiler Correct Answer- Converting high-level instruction into machine language. concatenate Correct Answer- To connect or link in a series or chain. constructor Correct Answer- A special type of function used to create a class or object. The constructor prepares the new object for use. def <Name>(<Parameters>): Correct Answer- Defines a function in Python. dictionary Correct Answer- Provides a mapping between keys, which can be values of any immutable type, and values, which can be any value. Because this is implemented using a hash table, the time to lookup a value does not increase (significantly) even when the number of keys increases. Division Operator Correct Answer- / Editor Correct Answer- Writing the program.encapsulation Correct Answer- Surrounding something to both keep the contents together and also to protect those contents. In Object Orientation this refers to the idea of taking our attributes and behaviors and bundling them together in the same unit, or the same class. Exponent Operator Correct Answer- ** expression Correct Answer- Any Python construct that has a value False and False Correct Answer- False False and True Correct Answer- False False or False Correct Answer- False False or True Correct Answer- True for <Name> in <Collection>: Correct Answer- Executes a block once for each element of a collection. For Loop Correct Answer- Uses a counter to control iteration. framework Correct Answer- Huge amounts of code already written, already tested, ready for you to link to and use within your programs. Also called libraries. function Correct Answer- In programming, this is a named section of a program that performs a specific task. It only executes when invoked. Is able to [Show More]
