Creating Software

1. IDE

   • Integrated development environment
   • TREE
     • Translators
       • Compiler and interpreter
     • Run time environment
     • Editor
     • Error diagnostics
       • Debugging tools
   • Examples
     • PyCharm
     • PyScripter
     • Python IDLE (used in schools)
       • Editor
         • Color codes command words
         • Auto indents code
         • Some also autocomplete code as you type it
       • When you run the code, a translator is used to translate the high level code into low level code
       • Error
         • Used to debug your code. it locates errors and suggests ways in which to fix 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 using the program

2. Translators

   • Machine code
     • 1st generation
       • A 1st generation translates all of the original program code into an executable program
       • No language translate needed
     • A collection of binary digits (1s and 0s)
   • Assembly language
     • 2nd generation
     • Assembly language uses a very simple command rather than a collection of numbers, allowing humans to more easily read computer code
   • Compiler
     • Translates the entire source code in one go
