1.2.1 - 1.2.3 Notes

Question 1

a group of instructive code that exists as an independent unit, which is easy to use with other code as needed

Answer 1

modular code

Question 2

one type of abstraction, that provides a name for a process, may extract features in order to generalize functionality (allows reuse), allows the program to execute the statements within a procedure before continuing

Answer 2

procedural abstraction

Question 3

the process of breaking a complex problem or system into parts that are easier to understand, conceive, program, and maintain

Answer 3

problem decomposition

Question 4

a named group of programming instructions that may have parameters/return values

Answer 4

procedure

Question 5

a trigger from the user or from a program that causes a specific part of the program to execute

Answer 5

event

Question 6

connecting an event to a function

Answer 6

event handling

Question 7

program statements are executed when triggered rather than sequentially

Answer 7

event-driven

Question 8

a variable that can be used in any part of a program

Answer 8

global variable

Question 9

similar to a list, declared by parentheses, but cannot be edited/changed within the code

Answer 9

tuple

Question 10

common method for referencing the position of elements in a list or string using natural numbers

Answer 10

list index

Question 11

each item in a specific location in one list correlates to the item in the same location within another list

Answer 11

parallel lists

Question 12

attaching two things side-by-side with strings of text

Answer 12

concatenate

Question 13

an ordered collection of items or values

Answer 13

list

Question 14

native type of Python representing a sequence of characters

Answer 14

strings

Question 15

any value that a method or function gives back ti the statement command from which the function/method is called

Answer 15

return values

Question 16

used to test the relationship between two variables, expression, or values

Answer 16

relational operators

Question 17

compare two Boolean expressions using and, or, not

aka Boolean operators

Answer 17

logical operators

Question 18

helps to detect is a key will/won’t work when pressed by the user

Answer 18

onkeypress

Question 19

the value that are sent to the function when it is called

Answer 19

argument

Question 20

the input variables of a procedure, a set of information included to help a process or function operate as intended

they are declared when writing the function

Answer 20

parameters

Question 21

a fixed value in source code such as 5 or “hello”

Answer 21

literal

Question 22

a repeating portion of an algorithm, repeats a specified number of times or until a condition is met

Answer 22

iteration

Question 23

parts of a algorithm are executed based on a condition being true/false

Answer 23

selection

Question 24

application of each step of an algorithm in the order in which code statements are given

Answer 24

sequencing

Question 25

a literal value ( 5 or “hello”), that is hard coded into a program instead of being assigned to a well-named variable. When used in large programs, they can be hard to find, their purpose hard to learn, and debugging them difficult

Answer 25

magic numbers

Question 26

very common concept in comp sci and info tech meaning that a lot of detail of a system or a process is hidden, allowing the user to focus on the important details Ex: lists, functions

Answer 26

abstraction
