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.

While Loop in python : How to become a Python Jedi - Beginners Python Programming Tutorial - Part 6

Welcome back friends to another post on TheCodingProject and we are back with the sixth chapter of the Beginner Python programming tutorial - How to become a python Jedi. This time we are going to learn how to use while loop in python.
The While Loop statement? In Python Programming, There are 3 types of loops →
While loop For loop Nested loops
Now to get into some action→
Let’s consider that two groups of aliens have landed on earth  out of these two one of the group is good & the other are the bad guys. The govt. Has given you the task of designing a system that takes in input from different eyewitnesses & then classify that whether the aliens that these eyewitnesses encounter are the good guys or bad guys.










Copy & paste the above code in your editor and run this code. What do you get ? When the input is Autobots it matches the condition aliens == "Autobots" & it enters the loop to prints the statement pointed by the print method.
We can also use negative conditions…

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…

For Loop in python 3 : How to become a Python Jedi - Beginners Python Programming Tutorial - Part 7

I am back again with another part in the beginner python programming tutorial series. We will continue with "Loops" but this time we are going to learn how to use for loop in python 3. 


Difference between For loop and While Loop
A "For Loop" and "While Loop" have a common connection that both are looping statement, but major difference is that unlike while loop, a for loop gets executed a specified number of times.



We can break down the For loop into the following components(Refer to the for loop flow chart below).
for keywordvariable namecall to the range functioncolon operatorclause or block of code Hovering over the flow-chart
The above flow-chart is..well horrible I know, but I make my own drawings because I can't afford an artist. So, bear with me. In the above flowchart is a very basicy, laymanish representation of a for loop. The decision box contains the For statement along-with it's soulmate i.e the Range function. As long as the variable I …
