What is python?

  • Python is a type of programming language executes the program directly by translating each statement into a sequence of one or more subroutines, and then into machine language.
  • It’s a high level language.
  • It’s a stand alone executable software so Python-based code can be distributed and can be used on various environments. It’s designed to be highly standardized, with a clear protocol for any task.
  • The main aim of this language is to make programmers write codes easily for small and large projects.

Why python?

Easy to understand:

If it is your first time programming, Python is a great choice because its friendly and easy to learn compared to most other major programming languages (like C ,c++ and java), with fewer exceptions and special cases.It handles a lot of complexity for you. Python also uses plain English keywords.

Use-ability:

Even though it has not yet been adopted as a first language by many computer science programs, Python is widely used by industry experts to code programs. It can run on a wide variety of hardware platforms and has the same interface on all platforms. Python provides a better structure and support for large programs than shell scripting. It supports for an interactive testing and debugging.

Libraries :

Python has been around for over 20 years.There are currently 118932 packages here, being an open source programming language, a lot of this has been released for others to use.  The Python Package Index is a repository of software for the Python programming language. Almost all of it is collected on https://pypi.python.org, You can install this software on your system to be used by your own projects. There are libraries for pretty much any use from image manipulation, to scientific calculations, to server automation. 

GUI(Graphical user interface):

Python supports GUI applications that can be created and shared to many systems. GUI makes python written programs to be more interactive. Various GUI toolkit like PyQt, PyGtk, wxPython etc are available which help developers create highly functional (GUI).

Availability of resources:

The standard implementation of Python, CPython, is free and open source. All the materials used to become a coding master from beginner level is available on the net (check out our further blogs as well for the information).

Difference between Python 2 and Python 3:

Before getting too excited about learning python lets see the difference between Python 2 and Python 3.Choose either one of them so that it’ll not be confusing for you in the future. Each version has its own pros and cons.

Overall difference: Python 3 is the latest generation of the language although many programmers still use Python 2.7 because python 2 was developed in the late 2000s so programmers tend to continue that trend. It’s not difficult to transfer code from Python 2 to Python 3 with a few modifications. Python 3 was released in late 2008 to modify the flaws in the python 2. Now a days Python 3 is slowly gaining more developers.

Code Difference:

  1. Print: In Python 2 print is treated as a statement instead of a function.
    Eg: print “Hey there! Whats up?”
    In Python 3 print() treated as a function.
    Eg: print(“Hope you are doing well”)
  2. Unicode support: Python 2 will handle the string as ASCII. ASCII is not a very flexible method for encoding characters especially non english characters. Python 3 stores strings as Unicode by default which is much better than ASCII.
  3. Division with Integers : Python 2 treats any number that you type without decimals as integer by default. But while dividing using integers you might not get the most accurate answer as you will receive a whole number ,you can still convert it to float and execute it. However, Python 3 will return the accurate decimal as a result by default which makes integer division more intuitive and easy to use.

Applications of Python

  • Artificial Intelligence.
  • Ethical hacking.
  • Machine Learning.
  • Deep Learning.
  • Games and 3D Graphics.
  • Big Data Analytic.
  • Robotics & IoT.
  • Blockchain.
  • Web and Android Applications.

What Type Of Jobs Are Available To Python Programmers?

Not only there’s a high demand and career opportunities for Python developers but also the job availabilities are growing daily due to the popularity of python.

  1. Research Analyst.
  2. Data Analyst.
  3. Web developer.
  4. Web designer.
  5. Game developer.
  6. Geospatial industry (like GPS, radar).
  7. DevOps Engineer.
  8. IoT Developer.
  9. Android Developer.
  10. Data Scientist.

Future of Python:

“The Future” for Python and Python Programmers is bright because demand will be going up with every new computer sold. More computers means more customer demand for software. This will mean more people will use more software like Python in more places. The opportunity is massive and I don’t see it slowing down for decades.
