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: Mathematical Operators
Operator Description + Addition – Subtraction * Multiplication / Division // Floor division ** Power % Reminder Addition Output: Subtraction Output: Multiplication Output: Division Output: Floor Division Output: Reminder Output: Power Output: Precedence of Mathematical Operators Not all operators have the same precedence. Based on the operators’ priority/precedence, the evaluation sequence will change. Let’s check … 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.
Python: package
Python package is a collection of modules in a directory. To tell Python, that this directory should be considered a package, we have to add a file named __init__.py Python package is a directory that contains a __init__.py file and a set of modules. The name of the directory is considered as the name of … Read more
Python: Function
Functions enable us to isolate and encapsulate a certain piece of code into its own block. And then it can be used in different places of the program without repeating the same code over and over again. NOTES In Python, functions are first-class objects(entities), so a function can be- Let’s see how we can define … Read more
Python: if…else [Control Flow]
In the code, we sometimes want certain pieces to be executed, and we ignore certain parts of the code. Keywords like “if“, “else“, and “elif” help us with that. if Condition Using the “if” condition we ask the interpreter to execute the code under the “if” block, only if the provided condition. Check the general … Read more
