Introduction to Python



What is Programming Language?
--------------------------
1.A programming language is a set of rules that
provides a way of telling a computer what
operations to perform.

2.A programming language is a set of rules for
communicating an algorithm

3.It provides a linguistic framework for
describing computations
provides a way of telling a computer what
operations to perform.

Types of computer languages:
--------------------------
Machine Language :

     1.The fundamental language of the computer’s processor, also called Low Level Language.
     2.All programs are converted into machine language before they can be executed.
     3.Consists of combination of 0’s and 1’s that represent high and low electrical voltage.

Assembly Language :
     1.A low level language that is similar to machine language.
 2.Uses symbolic operation code to represent the machine operation code.
      Eg :
LOAD r1,b
LOAD r2,h
MUL r1,r2
DIV r1,#2
RET

High level Language :

1.Computer (programming) languages that are easier to learn.
2.Uses English like statements.
3.Examples are Python,C ++, Visual Basic, Pascal, Fortran and …....

What is Python?
-----------------
1. Python is an easy to learn, powerful programming language. The application development process much faster and easier
2. The programming language Python was conceived in the late 1980s, and its implementation was started in December 1989 by
    Guido van Rossum at  Netherlands as a successor to the ABC (programming language)
3. Python First release happened in 1991.
4. Python was named for the BBC TV show Monty Python's Flying Circus.


Why python?
-----------
1. Easy to understand
2. Beginners language
3. Portable
4. Less lines of code
5. Simple to implement
6. Huge libraries supports

Feautures of python:
-------------------
1. Easy to learn and use.
2. Expressive language
3. Interpreted language.
4. Cross platform language(windows,linux,mac)
5. Free to install and opensource
6. Object oriented language
7. Extensible, Awesome online community
8. Large standard library(numpy,scipy)
9. GUI programming (Tkinter)

Python Implemenation alternatives:
-------------------------------
1. CPython(stadnard implemenation of python)
2. Jython(Python for java)
3. IronPython( Python for .net)
4. Stackless (Python for concurrency)
5. PyPy ( Python for speed)

Python Packages :
---------------
1. Web devlopment - Django,Flask frameworks,Pylons,Web2py framworks.
2. Artificiat Intelligence : Scikit-learn,Keras,TensorFlow,OpenCV
3. GUI - TKinter
4. Desktop Applications : Jython, WxPython
5. Game Development : pygame
6. Testing : Spliter Tool,pytest framework
7. Bigdata : Pydoop,DASK,PySpark Libraries
8. DataScience : NumPy,Pandas,matplotlib,seaborn libraries
9. AWS : boto
10. Robotic process : pyro
11. Web Scraping : Beautifulsoup4,urllib2,mechanize
12. Devops & System Admin : Os,Sys,Shutil,Glob,Subprocess,PathLib,fabric
13. Networking : Twisted,socket,client and server

Who uses Python :
------------------

Data engineers, data scientists, System administrators and
developers. Python is not industry specific, but task specific—great
for data processing, business intelligence, and some application
development

Variables, Data Types and Math Operations

  In order to do anything interesting in a program, we must have the ability to store and manipulate values. What allows us to do that are what we call variables. Now a variable, simply put, is just named data storage. Now Java is a strongly ‑ typed language. Now what that means is that when we declare a variable like, in this case, we have a variable named data Value, we have to specify the type of that variable, in this case, it's what we call an int, something that can store integers. So, what that means is that the data Value variable can only store things that are compatible with the type int. As we go through the course, we'll talk about this idea of one type being compatible with another. Now when we declare a variable, we can, of course, then assign a value to it, so our variable data Value now holds the value 100. Now when we use variables, we can do it the way we've done here where we declare it, then assign it, or as a matter of convenience, we can declare them a...

JRE vs. JDK

  The JRE and the JDK are two terms you hear people mention very frequently in the Java world, and what they are the two parts that we need in order to run and create Java applications. The JRE is the Java Runtime Environment. JDK is the Java Development Kit. And so, the JRE is what you require in order to run Java applications, and end users normally install the JRE. They're the ones who are going to run our apps. The JDK provides the tools that we need to create Java apps. So, normally, developers are the ones who install the JDK on their machines. And in order to develop apps, you need to run them, so the JDK installation includes a JRE. So how does all this work together? If we sit down, and we type up a Java source file with our program code inside of it, and we want to go ahead and run that in some host environment, how do we do it? A host environment might be Windows, Linux. It could be Mac. It could even be a browser. It might be a phone running Android. How do we get from ...
