Ever heard the word “Django”? Most answer going to be ‘YES’

A scene from movie named Django Unchained

Not this one, I mean Python web framework = Django. If YES then congratulations you just have to read the blog completely else then congratulations you just have to read the blog completely.

What is Django?

Django is a web framework based on python that allow to create web application with ease. It is robust, monotype in nature, easy to understand and believes in less code(relief) by making the code reusable but how? We will see this later in example.

There are a lot of web framework present there…


Is Python interpreted or compiled?

Before this, let’s understand difference between compiler and interpreter.

Compiler: Compilation involves translating your human understandable code to machine understandable code, or Machine Code. Machine code is the base level form of instructions that can be directly executed by the CPU. Upon successful compilation, your code generates an executable file. Executing this file runs the operations in your code step by step.

Interpreter: it converts source code written by the developer into intermediate language which is again translated into the native language / machine language that is executed.

Let understand by a diagram:

Machine code…


When it comes to work human always find the easy way to do it because we are quiet lazy in nature. So, when it comes to do a work like programming and coding most of us(human) want a language in which the lines of code should be minimum to execute our problem. So, in this case Python have the higher priority to the rest of others.

What is Python- a snake or programming language?

Python is a snake but we don’t have to discuss it here, lets discuss about python programming language.

  1. Python is a high-level, interpreted, interactive and object-oriented…

What is Database?

In home you have refrigerator or fridge to store food, veggies and other items, so in electronic/digital world the food is called data and the refrigerator is known as Database.

What is NoSQL database?

Before NoSQL lets understand what is SQL database. SQL database has a defined structure to store data or information that is in the form of table(Row, Column) just like your refrigerator’s cabinet(well defined space).

SQL Database example

From above figure it can be noticed that all the data is in row, column format and none of the data is null. If any data is null or empty we have to write null there.


Whenever I meet an IT/ CS guy they usually ask besides coding/ language is do you know AWS, OpenShift, DevOps? I answer ‘a little bit’. But whenever I ask them “can you please tell me about the Booting Process of operating System”?

The Answer from other side: “he he you are a funny guy. Just power on the computer that's it.”

Booting means starting up a computer. It is a short form of bootstrapping.

Everyone knows what class representative/ monitor means, the person who tells everything to the teacher and becomes the favorite student.

Meet Prometheus an application that has the same characteristics but instead of a teacher it tells everything to the user using it. Prometheus is a monitoring tool that keeps an eye on every process and creates a graph for better visuals.

Why a monitoring tool?

Suppose you are a chief manager of a development team that handles a website like Facebook.com having a huge database and huge visitors.


Previous article: Beginner’s Machine Learning (ML)

Dealing with a real-life problem, there is hardly any dataset that has only one dependent variable. Taking the example of a SmartPhone, everyone owns a phone which has a vast specification and took a lot of time to buy it. Because the phone was chosen on the basis of requirement whether it is for PUBG, MasterChef or ‘ये रिश्ता क्या कह लाता है’ |

Here the dependent variable is your requirement and independent variables are the specifications. For our youth, the best example is:

and if you are really searching this then watch YOUTUBE VS TIKTOK

In the above example, the y=Tik Tok and the x1=camera…


Python whose syntax and libraries made everyone a programmer or a coder, just import the library, a little bit code, and a clean & clear output. “CODER”.

But what happens when python is integrated with scripting languages like HTML, JavaScript, PHP, and so on. Sounds awesome right…

Everyone mostly heard about Flask and Django, but for integration, I used CGI (common gateway interface).

What is CGI?

The common gateway interface (CGI) is a standard way for a Web server to pass a Web user’s request to an application program and to receive data back to forward to the user or…


The term ‘Machine Learning’ sounds quite fantastic and revolving in the air all time. Here we going to learn Machine Learning (ML).

Before heading towards ML there is some vocabulary to know:

Data- facts and statistics collected together for reference or analysis or things are known or assumed as facts, making the basis of reasoning or calculation.

Data

Data Analysis- Data analysis is a method in which data is collected and organized so that one can derive helpful information from it. …


a package installer

Talking about Linux (Redhat) when it comes to software or package there are three command to play with package. The extension of software in Linux is ‘rpm’ such as ‘firefox.rpm’.

But what is Package Manager?

Answer-A package manager deals with packages/software, distributions of software and data in archive files. Packages contain metadata, such as the software’s name, description of its purpose, version number, vendor, checksum (preferably a cryptographic hash function), and a list of dependencies necessary for the software to run properly.

The first one is “rpm” command, it is similar to the ‘double click on software’s setup in windows’…
