What is cyber physical system (CPS)?

A cyber-physical system (CPS) is a mechanism controlled by a computer based algorithm, strongly integrated with internet and its users. 

Examples of CPS are as follows: medical monitoring, process control systems, smart grid, robotics systems, autonomous automobile systems and automatic pilot avionics.

Python Comments

Python Comments can be used to
                  - explain Python code.
                  - make the code more readable.

Comments starts with a #, and Python will ignore them:
Single line comment
Examples
1)     #This is a comment
        print("Good Morning")
2)     print("Welcome") #This is a comment
3)    #print("Good Morning")
        print("Good Evening")

Multi Line Comments
Python does not really have a syntax for multi line comments.
To add a multiline comment you could insert a # for each line:
Example
#This is a comment
#written in
#more than just one line
print("good evening")

Multiline string(triple quotes)
multiline string (triple quotes) place your comment inside it
Example

"""
This is a comment
written in
more than just one line
"""
print("Hello, Good Morning")

What is Python ?

• Python is a programming language.
• Python is a case-sensitive language.
• It was created by Guido van Rossum, and released in 1991.
• Python is used for web development (server-side), software development and mathematics.
• Python can connect to database systems.
• Python can be used to handle big data and perform complex mathematics.
• Python is a cross-platform language,It means that Python works on different platforms i.e Windows, Mac OS X, Linux, Raspberry Pi, etc.
• Python has syntax that allows developers to write programs with fewer lines than some other programming languages.
• Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
• Python can be treated in a procedural way, an object-orientated way or a functional way.
• Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses.
• Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions and classes. Other programming languages often use curly-brackets for this purpose.
