How Python implements “Data Encapsulation”?


Data privacy or “data encapsulation” is provided by Python by default. In Python every variable or method is scoped within its parent code block. Look at the below function-
  1. def newcurrencynote():
  2. newnote = 2000
  3. print("This is new" + newnote + "currency note")
  4. print(newnote)
  5. print(example())

In the above function newcurrencynote() the variable newnote inside the function has “ local” scope within that function, in other words it is private to that functions only and is not accessible outside that function . So, the first print function gives an error stating that you should initialize the variable first and then print it, but since the second function is trying to access the function itself so it will print the value of the variable.

How To Install Tensorflow On Windows

Why I am writing this tutorial ?
Recently I have started learning machine learning specifically DeepLearning for one of my pet projects, and during this quest of mine I wanted to learn TensorFlow library which is developed by Google. Learning is one thing but first I needed to install the library, but there was this problem which I faced during the installation. I am using Anaconda as my package manager and trying to install the Tensorflow library on my work computer which is behind a proxy, installing directly from the anaconda cloud while behind a proxy always displayed a proxy error.

How did I resolve the issue? Well this is exactly what I am going to write down in the below tutorial. The Steps To Follow
Before we get all cosy with this short tutorial on Tensorflow installation, let me tell you that
this tutorial is on the assumption that you have already installed Anaconda on your machine and you know at least a few basic things or two about python.
If you want to learn basic pyt…

What I learned from writing a guest post

Recently I wrote a python tutorial for Datacamp, while writing this tutorial I learned a couple of things which I am going to share with you right here in my blog post. May be you can use my experiences in your own endeavours as a writer.
IdeaThe first step is idea generation. You can either search through any previous topics in your blog post if you have one or you can go through your past learning, experiences or any problem statement that you might have gone through and you will find that while doing that you can get tons of ideas to start your article. If you fall short of ideas then you can ask for help from may be your social media followings your friends or your family, for example I asked the people at Datacamp themselves and they suggested me a couple of topics which got me started on the right note. So, be prompt to ask for help and you will be surprised how easily you can crowd-source ideas and there's nothing wrong in it.

Encountering The Python
What is Python? As per Wikipedia “Python is a widely used high-level, general-purpose, interpreted, dynamic programming language.” Python is an open source programming language which was conceived in the late 1980s and its implementation began in December 1989 by Guido van Rossum (more on it here).
What kind of programing language?To give a better idea let's look at the below mentioned summary-
High level language- Python is a high-level language because it provides strong “abstraction”.Interpreted - Python is an Interpreted language because it does not run on a compiler.Dynamically typed language - Python is dynamically typed because in python every variable is bound to an object.Why should I learn Python?Python is a very powerful programming language, secondly it's easier to learn and since it's interpreted language the code is easier to understand. Lastly there is a huge community supporting Python so if you get stuck anywhere lot's of help are a…
