Python 2/3 Note

1. How does Python work?

Python gets wirtten some code, we use some translation service called an interpreter(it will translate our code line by line) to run our code and then, our shell will spit out some instruction for our machines.

2. What is a good code?

1. use space make code clean
2. readability, is easy to understand, name does not confuse, comments
3. predictability
4. DRY, do not repeat again gain

3. What do we need scope ?

why do we put everthing in global? Our machine does not have infinite memory power.
Nonlocal can reduce use location in memory, once we termine our function that will destroy all variable in this function, soon we can not call variable in this function. It is nice feature in Python.

3. What is the Functional Programming?

Functional programming is all about separation of concerns, It´s all about packaging our code into separate chunks so that everything´s well organized in each part od our code. PURE FUNCTIONS
