🧠 Big Idea 3 - Unit 1

📅 October 11, 2024

Summary

This lesson introduces core programming concepts like variables, naming conventions, and basic data types in both Python and JavaScript. Key data types include:

• String – text within quotes (e.g., "Hello")
• Integer – whole numbers (e.g., 7)
• Float – decimal numbers (e.g., 7.5)
• Boolean – true or false values (True, False)
• Array / List – collections of values ([1, 2, 3])
• Object / Dictionary – key-value pairs (e.g., {"name": "Kush"})

The lesson also compares different variable naming conventions: snake_case, camelCase, and PascalCase.

# String & Integer variables
subject = "Math"
birthday = "August 38th"
favoriteNumber = 7

# Boolean values
cold = False
busy = True
print(cold)  # False
print(busy)  # True

# Dictionary with a list
my_stuff = {
    'name': "Soumini",
    'age': 14,
    'subjects': ['Math', 'Chemistry', 'CSP', 'English', 'History'],
}
print(my_stuff)

name = "Soumini"
age = 14
favorite_number = 7.0
favorite_food = "none"         # snake_case
FavoriteHobby = "reading"      # PascalCase
favoriteColor = "all colors but mostly purple"  # camelCase

myList = [name, age, favorite_number]

me = {
    'name': name,
    'age': age,
    'favorite_number': favorite_number
}

// Variables
let fav_subject = "math";
let hobby = "reading";
let number = 7;

// Object
var event = {
    date: "September 36th",
    time: "4 pm",
    thing: "Birthday Party",
    location: "Saturn the Planet",
    participants: 30,
};
console.log(event);

// Concatenation and math
let first = 61409;
let second = 90709;
console.log(first + second);  // Adds numbers

let one = "I don't like ";
let two = "bell peppers";
console.log(one + two);  // Combines strings

let name = "Soumini";
let age = 14;
let favorite_number = 7.0;

let me = {
    'name': 'Soumini',
