1. IDE

   • Python IDLE 3.5.0
   • PyCharm
   • PyScripter

2. TREE

   • Translators (Compiler and Interpreter)
     • When you run the code, a translator (such as an interpreter) is used to translate the high level code into low level code.
   • Editor
     • Colour codes command words Auto indents code Some also autocomplete code as you type it
   • Run Time Environment
     • Allows you to run your code quickly so that you can test to see that it works. This is used during iterative testing (Testing when you are developing the program.
   • Error Diagnostics (Debugging tools)
     • Used to debug your code. It locates errors and suggests ways in which to fix it.

3. Translators

   • 1st generation
     • Machine code (1's and 0's)
   • 4th generation
     • Facts and Rules are stated e.g. SQL or prolog ( an A.I. language)
     • Known as a Declarative Language
   • 3rd generation
     • A high level language e.g. python
     • Compiled or interpreted
     • One high level instruction = many machine code instructions
   • 2nd generation
     • Assembly language: uses a simple command for each collection of 1's and 0's. Uses an assembler to convert to machine code
     • One assembly code command = One machine code instruction
