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…

Collatz sequence python : Monday fun with Python

Hello everyone. Today is Monday..well not a big deal and I know everyone knows today is a Monday. Like you I'm not a big fan of Monday, although nowadays I'm waiting eagerly for this day of the week as I get to watch a Game of Thrones episode on this day and I'm sure most of you can reciprocate the same feeling. The only thing I hate the most is the long wait till Monday night till I return to home from office and get to watch that episode for which I wait for one whole week and here I am in office waiting for the day to get over soon.

The plan To kill the time I do one of the thing that I love the most. Yes, you guessed right? I code. So, I decided to fool around some python programming code to kill the boredom. Without much ado let's code :) I decided to device a python program that would help me to devise a "collatz sequence" In case you are thinking what a "collatz sequence" is then dive into this link here.

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…
