Programming

Programming

1. Procedural Programming

   • Sequence of Commands
   • Runs in Order

2. Functions

   • Tell a program to do something
   • e.g. print(), input(), round()

3. Methods

   • Methods are functions that are contained in a group of functions called an object
   • e.g Random.randint(), Random.random(), Turtle.forward()

4. Arguments

   • Extra information to allow functions to run
   • ("Goes in the brackets after the function")

5. Variables

   • A name assigned to a value
   • Can be used over and over again in the code
   • Can change throughout the code
   • variable = "assigned like this"

6. Strings

   • A + symbol can be used to connect strings, this is called concatenation
   • The input() function always returns a string
   • Casting turns one data type into another
   • You can cast a string to an integer by adding an int() before the input

7. Data Types

   • Whole numbers (integers) are stored as Binary
   • Words (or strings) are stores as ASCII
   • Real numbers (or floats) are stored using floating point binary
   • True or False (or Boolean) can be stored using a single 1 or 0
