Day 1:

Agenda :

• Introduction to python
• Python Features
• Python Comparison with other language.

Introduction to Python:

• Python is high level object oriented scripting language.
• Python is open source language.
• Platform Independent

Python Features  :

• Python is Interpreted
• Python is Interactive
• Python is Object-Oriented(classes, objects, polymorphisom, ecapsulation etc...)
• Python is a Beginner's Language 

• Python Comparison with other languages   :

History :

1. The implementation of Python was started in the December 1989 by Guido Van Rossum at CWI in Netherland.
2. In February 1991, van Rossum published the code(labeled version 0.9.0).
3. In 1994, Python 1.0 was released with new features like : lambda, map , filter, and reduce.
4. Python 2.0 added new features like: list comprehensions, garbage collection system .
5. On December 3, 2008 , Python 3.0 (also called "Py3K") was released.
6. Python is influenced by:

                  ---- ABC language.

                   ---- Modula -3

Python used in Various applications :

• Web Development 
• Testing(ex;  Hadoop, Selium etc...) 
• Data Analysis
• Data Science
• Artificial Intelligence.
• Machine Learning 

Top Companies Using the Python:

• Dropbox
• Yahoo!
• NASA
• IBM 
• facebook
• Youtube
• Mozilla 
• Google

Day 2:

Agenda :

• How to install Python On Windows
• Different ways to Run Python code

Download and Install python on windows:

Python official website : 

https://www.python.org/downloads/

 After installing python idle we get the command  window like this:

• every python files must save with the ".py" extension.

Simple Hello World Program in Python:

                 

                  print("Hello World")

output:

                

                  Hello World

Day 3:

  Agenda :

• Variables
• Datatypes
• Concatenation

Variables:

• A variable is nothing but a reserved memory location to store values.
• Variables are used to store the data.
• Memory allocated when  the values are stored in variables.
• Every variable must have some type.

                 a=10 

               Here a is the variable and 10 is the value .i.e; this value 10 is stored in the variable a;

In c,java,c++ we must specify the data types. Where as in Python , on need to specify the type. It will automatically considered. This concept is called Dynamically typed Programming language.

So Python supports the Dynamically Typed Programming language.

Means : When ever we assign the value to the variable python will automatically take the  datatype will be treated.

Examples:

1.    a=10          ------>   Integer Type
2.    b=50.385     ---------> Float Type
3.    name="Ramu"  ---------> String Type
4.    x=True           ------------> Boolean Type

small example on Variables:

    a=10

    b=50.48

    name= "Nani"

     x=True

    print(a)

    print(b)

    print(name)

    print(x)

output :   

              10

              50.48

               Nani

               True
