Intro

Represent a value with a variable
Strings, lists, booleans, numbers
Determine the value of a variable as a result of an assignment

Defining in Pythin

To define a variable in python, just type in the variable name - one word - and use the = sign to set it equal to it's value.
variable can be defined using numbers, string, list, or boolean
Strings must have quotations around it
lists must be surrounded by square brackets

boolean: T or F

- define dictionary w curly brackets
    - create a new key and set it equal to a value
- can use floats ( a decimal)
    - can do division, multiplication, print them

Javascript

- var name = value;
- can use algebra
    - var x = x + y
- const also defines a variable

Boolean

- w = 6 and q = 5
- if w>6 boolean returns ture

Data Abstraction in Python

Manages complexity in a program and makes code easier to implement
differnt variables can hvae the same object
can split and join lists and the data inside them

numbervariable = 25
stringvariable = "i am so sleepy"
numberlist = [1, 2, 3, 4, 5]
listofstrings = ["red", "orange", "yellow", "green", "blue"]
israining = False

print(numbervariable)
print(stringvariable)
print(numberlist)
print(listofstrings)
print(israining)

25
i am so sleepy
[1, 2, 3, 4, 5]
['red', 'orange', 'yellow', 'green', 'blue']
False

number = 5  #defining the variable number
x = number * 2  #defining a variable by using another variable
print(number*2)  # multiplying a variable by 2
print(x)

10
10

list = []
list.append("flowers")
list.append("fruits")  # appending a value to a defined list
print(list)

['flowers', 'fruits']

mydictionary = {"dogies":"animals"}  # defining dictionary using curly brackets
mydictionary["banana"] = "fruit"   #add keys and values to a dict by setting a value equal to a key, like shown
mydictionary["couch"] = "furniture"  #editing a value inside the dictionary
print(mydictionary)

{'dogies': 'animals', 'banana': 'fruit', 'couch': 'furniture'}

// boolean in javascript
Boolean(w > q) //true
Boolean(w < q)  //false
