command line interface

where you type commands on the keyboard at a prompt to tell the terminal what to do

where you start your terminal and REPL

to start a code

type python into your terminal, otherwise nothing will ever happen

REPL

read execute print loop

top box in python

used to edit a module of code that will eventually be run in the terminal or Trailhead

Boolean

a type of data that evaluates to True or False

technically they are strings but they are typed as bools

used when making logical decisions

indexing

using [] to pull a variable out of a line and print it alone

%

used to find remainders when dividing two numbers

remainders will pretty much only work with positive whole numbers

len()

used to find the length of a string

isalpha

used when strings are only made up of alphabetical letters

isdigit

used when expressions are only made up of digits

algorithm

a series of steps that end up producing a result

high-level

can also be expressions (a single int can be an expresssion)

conditional statement

statements that only happen if and only if something else occurs

assignment operator

assigns a variable some value

used to assign local variables usually

pseudocode

fake code, simplified

used to write out code before actually typing it in

loop statement

a statement that performs an action only a certain number of times

identifier

the function's name

ex. tea_bags

->

leads to the return type of the function

string concatenation

a joining of multiple elements

floats

will always prevail in terms of PEMDAS - they are the most precise

string x int

you can multiply a string times an integer and it will print as expected

return keyword

need to have this in there for a function to return an output

signature

the whole top line of the function

stack

shorter term memory of Python

names and frames are stored here

heap

definitions are housed here, longer term memory

keyword argument

specifies the name of the parameter

functions

used to help you extract from processes, go higher level

function call syntax

need a function name and argument list

function definition syntax

def function name (parameter list) -> return type:

docstring

what you function does

==

to show if too things are equal

expressions

can totally switch them out if they evaluate to the same type

string comparison

doesn't always work the way you think it will - be very careful
