Python

Python

1. Programming language

   • Even kids can use it
   • It's very popular
     • Used by software engineers, mathematicians and data analysts

2. Algorithms

   • The steps we give computers to solve problems
   • Precise steps to solve problems in computing
   • The simplest steps available

3. Sequencing

   • Computers use a lot of sequencing
   • Order is important
   • Accuracy is important
   • It is putting steps in order

4. Debugging

   • Taking problems out
     • Removing errors from the coding

5. IDLE Python

   • Save Python files as (insert filename).py
   • Keep variables the same
     • eg: X needs to stay as X and not change to x
   • Python example: m=5 n=6 t=m+n print t
   • IDLE = Integrated Development Environment
   • Has two modes
     • Interactive and script mode
       • Interactive mode lets you see your progress as you type the code

6. Decomposition

   • Breaking steps down
     • Then problems can be solved (easier)
   • Decomposition leads to algorithms being made
