OOP and Design Pattern:

Association, Aggregation and Composition:

The distinction between aggregation and composition goes to old times for language like C++ where there is manual memory management. For languages with dynamic memory management everything is compositon.

Association: Multiple objects have their own life cycle and there is no owner. Ex teacher and student, independent life cycle.

Functions

List Operations:

++ == extends

:+ == append

REST Design Important Points:

1. Use Nouns but no Verbs

Ex: /cars, /cars/23 ... Correct

/getCarData, /get/car/data ... wrong

2. GET method & query parameter should not alter the state use PUT, POST and DELETE for changing the state
3. Do not mix up singular and plural nouns use only plural nouns

Subprocess:

One class Popen and others are wrapper over it. 
shell=True: This argument spawns a new intermediate process and run the command. If False, the command run in current process.

Popen: non blocking

subprcess call vs Popen:

call: is a wrapper over Popen and takes all the pamaters of popen. It is blocking and does not return until process has        finished.
