Lesson 1: Python

Lesson 1: Python

1. Python is a simple coding language

2. Program on Python IDLE

   • De-bugging is taking the bug out of the code
   • You need to be consistent with lowercase or capitals
     • not m=25 n=25 T=m-N
     • e.g m=25 n=25 t=m-n

3. Development environment

   • Called IDLE
     • Intergrated Development Environment
     • 2 Modes
       • Interactive mode where you can see your results as soon as you do it. Generally used for small amounts of code.
       • In script mode you write your code in a text file then save it with a . py extension which stands for "Python". Generally used for larger amounts of code.

4. Used around the world.

   • Used by NASA, Google, etc.
     • Can be used for AI, data collection etc.

5. You need to sequence instructions

   • Once you put the steps in order, it is an algorithm
     • The steps we give to the computer is the algorithm. They need to be simple steps.
     • If it's in the right order, it's an algorithm
     • The action of breaking apart the problem into smaller steps which leads you to find an algorithim is called decompostion; the simplest precise steps
