Python for Absolute Beginner

In this ebook, we thought you absolute beginning in python I believe that the best way to learn python is to read our ebook. In this ebook, we are referring you to some interesting or valuable points on python.

So let us have a look.

Why learn Python as an absolute beginner?

Before exploring, we have to understand its structure and the process.

It is divided into two categories.

1) Application

2) Organizations using Python Language

Application :

  •   GUI-based desktop applications (Games, Science, and many other things)
  •   Web frameworks and development applications.
  •   Enterprises and Business applications.
  •   Operating Systems.
  •   Language Development.
  •   Prototyping.

Organizations using Python Language :

  •   Google (components of Google spider and its search engine‚Äôs etc)  
  •   Yahoo(maps) 
  •   Youtube or Facebook.  
  •   Mozilla.  
  •   Dropbox.  
  •   Microsoft.

Introducation 

 1. So Python is an object-oriented programming language. In Python, we thought the main emphasis is on function and object-oriented programming stress objects.

2. Object means a collection of data and methods acting on those particular data. Python runs on an interpreted system, meaning that code can be executed as soon as it is written.

Basics that every Python developer has to know.

Guido van Rossum developed Python in early 1990 and its latest version is Python 3.7.1, we can simply say that Python 3 or 3.0 was released in 2008 and it is very easy to understand.

Installation of Python on your system

  • Select any updated Version of Python to Install.
  • Download Python Executable Installer.
  • Run Executable Installer to Run.
  • Verified that Python was Installed on Windows.
  • Verify Pip Was installed.
  • Add Python Path to Environment Variables (it is optional)
  • Install virtual (it is also optional)
  • Installation completed verified it on command section that which type’s of the version you installed on your system.

Making your first simple Program using Python

Navigate to a folder that you would like to create your first python file in, and create a file called test.py. Now open this file up in the editor and type the following code: print “Hello, World!” 

code shows like Hello, World!

Now we will write anything in print and it will print in the program Python.

Input or Output

Developers often need to interact with users, either to get some data or to provide the result. Most of them use dialog boxes as a way of asking the users to provide some type of input. At the same time, Python provides us with two inbuilt functions.

Data Types in Python

Data Type is essential in the concept of Programming.

Variables can store data of different types, and the data can do different things.

Python Numbers 

There are three types of numeric in Python :

  • int
  • float
  • complex

Variables of numeric types are assigned when you create a value for them.

Example :-

x = 1 #int

y = 2.8 #float

z = 1j #complex

Explain Int

Int or integer is a whole number, negative or positive number, of ultimate length without any decimals.

Explain Float

A float or floating-point number is a number negative or positive, containing one or more than one decimals.

Explain Complex

Complex numbers are written with an “a” as the imaginary part.

Making Choices

So far we learn many commands know we have to choose or compare things like greater or smaller, true or false, by giving conditional statements.

Values can be compared by using some comparison operators:-

  • < less than
  • > greater than
  • = equal to
  • != not equal

Doctypes:-

It refers to a document type that helps browsers to understand the version of Python the document is written in better than any other document present on the internet.
