8 Popular Encryption methods real Usage

By
Encryption works as it replaces original data with some special characters and stores the data. You need a private key to decrypt the data. Else it is not possible to understand encrypted data even for hackers.

Private keys are two types. Sender uses one private key and receiver uses one other private key.
I have given in this post about 8 encryption methods.

Python for Loop Print rows using List concept

By
For loop is crucial for your python programming. Out of all the For Loop options, the list option is so popular. If you know, how to use this concept, you can write any number of programs quickly and with less effort.

Using for loop you can get index for list items. You can print list elements using for loop.

If you take any language, the loops play a vital role.

The use of For Loop When you want to deal with data of multiple values, you need loops. So, For Loop is so famous because, you can control multiple input values.

Syntax For Loop for i in my_list: print(i)
The 'i' says variable that represents value in the 'my_list'. The for helps to iterate the list values one by one.
Example Program For Loop List in Python my_list=[2,3,4] for i in my_list: print(i)

Block storage vs object storage real differences

By
Interesting questions, I am giving on the two different types of storage popular in Amazon aws. Those are Block and Object.
Object vs Block Storage in AWS Why these names are different. You need to understand storage available in AWS. You alreday know that AWS is leading provider in cloud computing.
Object StorageObject means it is a single object. You are not dividing here.In the context of AWS, object storage helps your file to store as -is. How big it is does not matter.Suppose, your file size is 10MB, it stores as 10 MB file.What happens when you update a 30MB file, simply, it deletes old object and create a brand new object.Even, for small change, you need to update whole file. So, it utlilizes lot of resources. Object storage is much better for big file and very few changes.The object storage is well managed by AWS .AWS has full control over Object storage.Block StorageBlock storage divides your file into blocksYou have selected a block size as 512 bytes, then you want to upload…

Three popular RPA tools functional differences

By
Robotic process automation is growing area and many IT developers across the board started up-skill in this popular area. I have written this post for the benefit of Software developers who are interested in RPA also called Robotic Process Automation.


In my previous post, I have described that total 12 tools are available in the market. Out of those 3 tools are most popular. Those are Automation anywhere, BluePrism and Uipath. Many programmers asked what are the differences between these tools. I have given differences of all these three RPA tools.

BluePrism Blue Prism has taken a simple concept, replicating user activity on the desktop, and made it enterprise strength. The technology is scalable, secure, resilient, and flexible and is supported by a comprehensive methodology, operational framework and provided as packaged software.The technology is developed and deployed within a “corridor of IT governance” and has sophisticated error handling and process modelling capabilities to ens…

Python Syntax Rules Eliminate Errors Before you start debugging

By
In Python, if you know syntax rules, you can eliminate errors. The basic mistakes programmers do are missing semicolons, adding extra commas, and extra spaces. Python is case sensitive. So using the wrong identifier gives an error.
Indentation is unique to Python. You cannot find this kind of rule in any other programming languages Python Syntax Cheat Sheet These are the main areas you need to focus while writing a Python program. You need to learn rules. Else you need to waste a lot of time fixing the issues or errors.
Indentation or Syntax ErrorsExceptionsHandling Exceptions
1. Indentation If you do not follow proper order, you will get an error. The details of one block shroud follow in one vertical line. The sub-block should be inside of that.

In if loop, the if, elif, and else should have same indentation. Not only, the statement inside of them should have same indentation.Understand these examples a good material on indentation for you.   2. Exceptions  Python raises exception, wh…
