Python Basics

Comments Data Types Strings Numbers

Comments

You can write text that the program will ignore by beginning the line with a #, this helps with reminding you what certain code does or for explaining purposes.

py # This is a comment

Data Types

Variables can store data of different types, and different types can do different things.

Python has the following data types built-in by default, in these categories:
Text Type: str
Numeric Types: int, float, complex
Sequence Types: list, tuple, range
Mapping Type: dict
Set Types: set, frozenset
Boolean Type: bool
Binary Types: bytes, bytearray, memoryview

We will go more in-depth on some of these types in the next few paragraphs.

You can print the data type of a variable with the type() function:
py x = 5 print(type(x))

Strings

Strings are surrounded by either single quotation marks, or double quotation marks.


py 

x = "hello" 

y = 'hello' 

# single quotations and double quotation marks are the same

x == y # returns True

You can assign a multiline string to a variable by using three quotes:
py x = """The FitnessGram Pacer test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter Pacer test will begin in 30 seconds."""

You can check the length of a string using the len() function: py x = "hello" print(len(text)) # returns 5

Numbers

There are 2 primary, int and float

py x = 2 # int y = 2.8 # float

To verify the type of an object in Python, use the type() function:py print(type(x)) print(type(y))

Int, or integers, are whole numbers, positive or negative, without decimals.

Float is a number, positive or negative, containing one or more decimals.

Both strings and numbers are built-in data types.

C++ Basics

Strings Integers and Floating Point Numbers Print

Strings

A string is a sequence of characters representing text. Strings are typically enclosed in quotation marks and can be stored in variables for later use in a program.

#include <ostream> #include <string> int main() { // Declare a string variable std::string str = "codinghome"; }

Integers and Floating Point Numbers

Simply said, Integers are used for numbers without a decimal, and Float is used for numbers with decimals, simply said. There is more to that but we are keeping it simple.

#include <iostream> int main() { // Declare an integer variable int num = 10; // Declare a floating-point variable float fnum = 10.5; }

Print

Printing an output to the terminal/console or whatever you want to call it.

#include <iostream> int main() { // Declare an integer variable int num = 10; // Declare a floating-point variable float fnum = 10.5; std::cout << "num: " << num << std::endl; // <-- Prints the integer Variable (Variable num) std::cout << "fnum: " << fnum << std::endl; // <-- Prints the floating point Variable(Variable fnum) }

HTML Basics

Example Document HTML Headings HTML Paragraphs HTML Links HTML Images

Example Document


<!DOCTYPE html>

<html>

<body>

<h1>My first Heading</h1>

<p>My first paragraph</p>

</body>

</html>

The <!DOCTYPE> declaration represents the document type, and helps browsers to display web pages correctly. It must only appear once, at the top of the page (before any HTML tags). The <!DOCTYPE> declaration is not case sensitive.

HTML Headings

HTML headings are defined with the <h1> to <h6> tags. <h1>defines the most important heading. <h6> defines the least important heading:
<h1>Big</h1>
<h6>Small</h6>

HTML Paragraphs

HTML paragraphs are defined with the <p> tag:<p>This is a paragraph.</p> <p>This is another paragraph.</p>

HTML Links

HTML links are defined with the <a> tag:
<a href="https://example.com">This is a link</a>

HTML Images

HTML images are defined with the <img> tag. The source file (src), alternative text (alt), width, and height are provided as attributes:
<img src="example.jpg" alt="example.com" width="104" height="142">

CSS Basics

Example Document CSS Rulesets Text Elements Padding Elements Color Elements Extra: Centering Images

Example Document


h1 {

  color: black;   

  text-align: center; 

  font-size: 26px;

  font-family: verdana;

}

<p style="font-size:10px">

To put CSS files in HTML, use... <link rel="stylesheet" href="style.css">

CSS Rulesets

Selector - p {
Property - color: red;
Declaration - }

Properties - With these, you can style a HTML element, like for example; color.
Property Value - This chooses one of the possible options for a given property, like red for color.
You can also write CSS like html{color:red;}
You can also put styles in HTML elements. <h1 style="font-color:white;">
You can also select multiple elements at once like...
h1, h4, h6, h2 { color: red; }

Text Elements

font-size: 10px; - Text size, can be in pixels.
font-family: verdana; - Fonts
text-align: center; - Can align to the left side, right side, or in the center of the webpage.
text-shadow: 3px black - Shadow of text. Can be in pixels and colors.

Padding Elements

padding-top: 50px; - Separation. Can be top, left, right, and the bottom in pixels.
margin: 50px; - A margin. Can be in pixels.
border-width: 5px; - Border width. Can be thin, medium, thick, or just pixels.
border-style: dotted; - Border style. Can be dotted, dashed, solid, double, groove, ridge, inset, outset, none, or hidden. Can also be colored.
width=500px; - Width of the element. Can be pixels or percentages.

Color Elements

color: red; - Color of the element, can be hexadecimal, or RGB.
background-color: white; - Background color of the element.

Extra: Centering Images

img {

   margin: 0 auto;

   display: block;

}

JavaScript Basics

Including JavaScript in an HTML Page Call an External JavaScript File Including Comments Variables Data Types

Including JavaScript in an HTML Page

<script type="text/javascript"> //JS code goes here </script>

Call an External JavaScript File

<script src="myscript.js"></script>

Including Comments

Single line comments - // Comment
Multi-line comments - /* comment here */

Variables

var, const, let
var — The most common variable. Can be reassigned but only accessed within a function. Variables defined with var move to the top when code is executed.
const — Can not be reassigned and not accessible before they appear within the code.
let — Similar to const, however, let variable can be reassigned but not re-declared.

Data Types

Numbers — var age = 23
Variables — var x
Text (strings) — var a = "init"
Operations — var b = 1 + 2 + 3
True or fase statements — var c = true
Constant numbers — const PI = 3.14
Objects — var name = {firstName:"John", lastName:”Doe"}

Objects Example
var person = { firstName:"John", lastName:"Doe", age:20, nationality:"American" };

FROM t

GROUP BY c1;

Filter Groups using Having Clause


SELECT c1, aggregate(c2)

FROM t

GROUP BY c1

HAVING condition;

Modifying Data

Insert One Row into a Table


INSERT INTO t(column_list)

VALUES(value_list);

Insert Multiple Rows into a Table


INSERT INTO t(column_list)

VALUES (value_list), 

       (value_list), …;

TRUNCATE TABLE t;

JSON Basics

Example Document Importing JSON

Example Document


{

  "foo": "bar",

  "array": [

    "foo",

    "bar"

  ]

}

All JSON files are surrounded by { and }, which means it is a object. Unlike Javascript, you must use double quotes (") for strings, not singular quotes (')

Importing JSON

JavaScript	`fetch('example.json')`
Node.js	`import('./example.json')`
TypeScript + Node.js	`import data from 'example.json'`
Python	`import 'json'; with open('data.json', 'r') as f: data = json.load(f)`
