Python is a general-purpose, high level programming language developed by Guido van Rossum in 1991. It was structured with an accentuation on code comprehensibility, and its syntax allows programmers to express their concepts in fewer lines of code which makes it the fastest-growing programming language in current times....

Before stepping into a new project, the software developing team goes through a severe discussion in order to choose the best language, framework, or methodology for their project. As we are aware, the different technologies have their different pros and cons and similarly the technology which is looking vibrant for one project might be lacking for others.

Every Ruby source file can run as the BEGIN blocks when the file is being loaded and runs the END blocks after the program has finished executing. The BEGIN and END statements are different from each other. A program may contain multiple BEGIN and END blocks. If there is more than one BEGIN statement in a program, they are executed in the order If there is more than one END statement, they are executed in the reverse of the order. the first END one is executed last. An open curly brace always come after BEGIN and END keyword. Syntax:...

Graphs are basic data structures that represent the connections between different items. They are made up of edges (links) that show the connections between the entities and vertices (nodes) that represent the entities themselves. Numerous applications, such as social networks, navigation systems, routing algorithms, scheduling issues, and more, heavily rely on graphs....

Before studying about Ruby Mixins, we should have the knowledge about Object Oriented Concepts. If we don’t, go through Object Oriented Concepts in Ruby . When a class can inherit features from more than one parent class, the class is supposed to have multiple inheritance. But Ruby does not support multiple inheritance directly and instead uses a facility called mixin. Mixins in Ruby allows modules to access instance methods of another one using include method. Mixins provides a controlled way of adding functionality to classes. The code in the mixin starts to interact with code in the class. In Ruby, a code wrapped up in a module is called mixins that a class can include or extend. A class consist many mixins....
