WGU C173 Study Guide Latest 2022
Already Passed
- ✔✔subtraction operator, outputs the difference between the two input numbers
!= ✔✔a comparison operator used to compare if one operator is not equal to another
% ✔✔modulo operator, outputs the remainder of dividing the first number by the second
* ✔✔multiplication operator, outputs the product of the two input numbers
** ✔✔exponentiation operator, outputs the result of multiplying <base> by itself <power> number
of times
/ ✔✔division operator, outputs the result of dividing the first number by the second
+ ✔✔addition operator, outputs the sum of the two input numbers OR concatenation operator,
joins two values together
< ✔✔a comparison operator used to compare if one operator is less than another
< ✔✔a comparison operator used to compare if one operator is less than another
<= ✔✔a comparison operator used to compare if one operator is less than or equal to another
= ✔✔assignment operator, assigns a value
== ✔✔a comparison operator used to compare if one operator is equal to another
,> ✔✔a comparison operator used to compare if one operator is greater than another
>= ✔✔a comparison operator used to compare if one operator is greater than or equal to another
abstraction ✔✔Focus on the essential qualities of something rather than one specific example.
actors ✔✔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.
algorithm ✔✔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() ✔✔Mutates <List> by adding <Element> to the end of the list.
argument ✔✔The inputs to a procedure. Also called operands.
attributes ✔✔Characteristics of an object which may be used to reference other objects or save
object state information.
<name> = <expression> ✔✔This is an assignment statement. 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.
base case ✔✔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.
Boolean ✔✔A value that is either True or False
, circular definition ✔✔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 ✔✔Describes what an object will be, but it isn't the object itself. This is a blueprint for that
object.
class <ClassName> (<BaseClass>):
<Block> ✔✔How to define a class in Python
class diagram (UML) ✔✔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 ✔✔Dividing software or an application into smaller modules. This provides
prewritten code which saves resources and provides greater manageability.
comparison operator ✔✔Used to make a comparison between two values.
compiled language ✔✔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 ✔✔A program that takes source code and converts it to machine code by producing a
separate file.
concatenate ✔✔To connect or link in a series or chain.
constructor ✔✔A special type of function used to create a class or object. The constructor prepares
the new object for use.
