Python Features

1.Easy

Easy to code :

Python is extremely easy to code. Compared to other popular languages like Java and C++, it’s easier to code in Python. Anyone can learn Python syntax in only a couple of hours. Though sure, mastering Python requires learning about all its advanced concepts and packages and modules. That takes time. Thus, it’s programmer-friendly language.

Easy to read :

Being a application-oriented language, Python code is sort of like English. looking at it, you’ll tell what the code is meant to try and do. Also, since it’s dynamically-typed, it mandates indentation. This aids readability.

2. Expressive

First, let’s study expressiveness. Suppose we have two languages A and B, and every one programs which will be made in B using local transformations. However, there are some programs which will be made in B, but not during a, using local transformations. Then, B is claimed to be more expressive than A. Python provides us with a myriad of constructs that help us specialize in the answer instead of on the syntax. this can be one among the outstanding python features that tell you why you should learn Python.

3. Free and Open Source

Firstly, Python is freely available. you’ll download it from the Python Website. Secondly, it’s open-source. this suggests that its source code is out there to the general public. you’ll download it, change it, use it, and distribute it. this can be called FLOSS(Free/library and Open Source Software). because the Python community, we’re all headed toward one goal- an ever-bettering Python.

4. High-Level

It’s a application-oriented language. this suggests that as programmers, we don’t need to remember the system architecture. Nor can we need to manage the memory. This makes it more programmer-friendly and is one among the key python features.

5. Portable

Let’s assume you’ve written a Python code for your Windows machine. Now, if you would like to run it on a Mac, you don’t need to make changes to that for an equivalent. In other words, you’ll take one code and run it on any machine, there’s no need to write different code for various machines. This makes Python a transportable language. However, you want to avoid any system-dependent features during this case.

6. Interpreted

If you’re aware of any languages like C++ or Java, you want to first compile it, then run it. But in Python, there’s no need to compile it. Internally, its source code is converted into an instantaneous form called byte code. So, all you would like to try and do is to run your Python code without fear about linking to libraries, and many other things. By interpreted, we mean the source code is executed line by line, and not all directly. due to this, it’s easier to debug your code. Also, interpreting makes it just slightly slower than Java, but that doesn’t matter compared to the advantages it’s to supply.

7. Object-Oriented

A programming language which will model the real world is claimed to be object-oriented. It focuses on objects and combines data and functions. Contrarily, a procedure-oriented language revolves around functions, which are code that may be reused. Python supports both procedure-oriented and object-oriented programming which is one among the key python features. It also supports multiple inheritances, unlike Java. a category may be a blueprint for such an object. it’s an abstract data type and holds no values.

8. Extensible

If needed, you’ll write a number of your Python code in other languages like C++. This makes Python an extensible language, meaning that it can be extended to other languages.

9. Large Standard Library

A software isn’t user-friendly until its GUI is formed. A user can easily interact with the software with a GUI. Python offers various libraries for creating Graphical interface for your applications. For this, you’ll use Tkinter, wxPython or JPython. These toolkits allow you for straightforward and fast development of GUI.

10. Dynamically Typed

Python is dynamically-typed. this suggests that the sort for a worth is set at run-time, not before. this is why we don’t need to specify the sort of knowledge while declaring it.

Python Language Introduction


Python is a widely used general-purpose, high level programming language. It was initially designed by Guido van Rossum in 1991 and developed by the Python Software Foundation.It was designed primarily to highlight the readability of the code, and allows its syntax for programmers to communicate concepts in fewer lines of codes.

Below are some facts about Python.

  • Python may be a widely used general-purpose, high-level programing language.
  • Python allows programming in Object-Oriented and Procedural paradigms.
  • Python programs generally smaller than other programming languages like Java and C++.
  • Programmers need to type relatively less and indentation requirement of the language, makes them readable all the time.
  • Python language is getting used by most tech-giant companies like – Google, Amazon, Facebook, Instagram, Dropbox, Uber… etc

The biggest strength of the Python is large library which may be used for the subsequent.

  1. Machine Learning
  2. GUI Applications (like Kivy, Tkinter, PyQt etc. )
  3. Web frameworks like Django (used by YouTube, Instagram, Dropbox)
  4. Image processing (like OpenCV, Pillow)
  5. Web scraping (like Scrapy, BeautifulSoup, Selenium)
  6. Test frameworks
  7. Multimedia
  8. Scientific computing
  9. Text processing and many more

Python is a programming language that permits you to work quickly and integrate systems more effectively.There are two major Python versions- Python 2 and Python 3. Both are quite different.

Beginning with Python programming:

  • Finding an Interpreter:


Before we start Python programming, we need to have an interpreter to interpret and run our programs. There are certain online interpreters like https://www.onlinegdb.com/online_python_interpreter, https://ideone.com/ or https://repl.it/languages/python3 that can be used to start Python without installing an interpreter.

Windows:There are many interpreters available freely to run Python scripts like IDLE ( Integrated Development Environment ) which is installed once you install the python software from http://python.org/
Linux:For Linux, Python comes bundled with the linux.

  • Writing first program:

Following is the first program in Python

#script begins
print("Hello Mr.Bigdata ") 
#output
Hello Mr.Bigdata

Let us analyze the script line by line.


Line 1 : [Script] starts in Python’s view #. So this statement is for readability of code and ignored by the Python interpreter.


Line 2 : [print (“Hello Mr. Bigdata”)] Python script is used to print on the console font function () but a line is printed (and including line drawing unlike C). The difference between Python 2 and Python 3 is the printed statement.. In Python 2, the “print” statement is not a function, and therefore can be invoked without parentheses. However, in Python 3, it is a function, and must be invoked with parentheses.

Python certainly is here for the long run. Are you?
