procedural programming

procedural programming

1. Coding in Python

   • Loops and Variables
     • Iteration is the process of repeating a section of code multiple times
     • A loop is the section of code that repeats under specified circumstances

2. computers don't think for themselves.

3. Everything that the computer does follows a clearly defined instuction

4. The simplest programmes are the procedural programmes because they are a sequence of commands that run in order

5. function and methods

   • methods in functions contain a group of functions called object
   • a function can tell the programme to do something.
   • each function does something difffrent
   • print() - displays some text in the console input() - gets some text from the keyboard round() - rounds a number to a given decimal place
   • Random.randint() - generates a random whole number Random.random() - generates a random decimal number between 0 and 1 Turtle.forward() - moves a turtle forward

6. Arguments

   • the brackets () are arguments which are extra data used at the end of a function

7. Python

   • Data is stored in a named store called a variable
   • We can name variables anything we like, as long as it starts with a letter
   • A + symbol can be used to combine strings together into bigger strings This is called concatenation
   • To make programs far more useful, we can get inputs from the user and store those in variables, which we can use later.
