Linux Command: clear and reset (with clear left and right hotkeys)
Use the following command to get a clear terminal screen. The following commands are handy and provide very easy-to-use options and/or shortcuts.
Linux Command: Piping (output of one command, as input of another)
Using the technique of piping we can send the standard output of one command as the standard input of another command. This way we can build a complex and advanced process(step-by-step) to perform complicated tasks.
Linux Command: cd (change working directory)
Use “cd” to change the working directory.
Linux Command: Aliases(create command aliases or shortcuts)
We can create a shortcut or alias of any command. This is useful when we have some complex command that we use frequently, and we want an easy way to run that command, instead of copying and pasting it over and over again.
Linux Commands
Linux commands are case-sensitive and are written in lowercase. Let’s take a look at some basic information about Linux commands, and then we will dive deep into the individual commands.
Python: Class and Object
An object in Python(and in general OOP) is a collection of data, and the behavior associated with the different aspects of the object. Object-Oriented Programming(OOP) refers to, objects being the primary focus while programming and modeling all real-world entities as objects. So when we analyze a problem, we need to identify 2 things- Class is … Read more

Python: Generator
Generator is a special type of function that produces a series of values over time. That means we can use a generate and get a value, then stop, and later get the next value. This is the process of lazy generation of sequence of values.
