One of the reasons that Python is so valuable is that there are several packages that we can install that extend the capabilities of Python. For example, if we want MATLAB-like functionality matrices numerical analysis, you can use numpy, optimizers, and differential equation solvers. Further, several other packages like matplotlib help us plotting, while Pygame helps develop a graphical user interface and build diverse games. xlwings, on the other hand, allows us to interface with excel. In addition, we have others like open CV, computer vision, etc.

Python packages are collections of modules (reusable code) that extend and improve the basic Python language’s capability. Python developers contribute to the official Python Package Index (PyPI ) repository, making their packages open source and available to the Python community. The Python Packaging Authority (PyPA ) is in charge of the repository and provides a collection of tools for creating, distributing, and installing Python packages.

Python IDLE is a primary and straightforward IDE with less functionality than other Python IDEs. Python IDLE has the following capabilities to make Python programming and testing easier. It has several essential features that we’ll examine deeply and see examples of later in this guide.

The Domain Name System, usually known as DNS, is an internet phonebook that contains information about domain names. DNS transforms domain names into IP addresses, allowing browsers to access the resources.

Bits are a stream of binary numbers that computers use to store many types of data. It ultimately comes down to ones and zeros, whether you’re working with text, photos, or videos. Bitwise operators in Python allow you to alter individual bits of data at the most granular level.

Python inner functions have a wide range of applications. They can be used to offer encapsulation and hide your functions from external access and write useful inner functions, closures, and decorators. In the following sections, you’ll learn about the first two use cases of inner functions in this section and how to create closure factory functions and decorators.

Managing the dependencies between projects is one of the most frustrating aspects of working with many Python projects. For instance, project A requires Python 2.7 and relies on older versions of a package. In contrast, Project B requires Python 3.7 and a slew of additional packages, including the most recent version of the same program.

Python Turtle graphics is a fun way for youngsters and beginners to learn the fundamentals of programming. However, to learn to program using Python Turtle, you must first comprehend why someone would want to program or draw with it.

Modern online applications are frequently created using a server-side language that serves data via an API and a front-end JavaScript framework that presents the data to the end-user easy-to-use. Python is a dynamic programming language that is widely used by businesses and professionals. The language’s core ideals indicate that software should be readable and straightforward, allowing developers to be more productive and happier.

Python Memory Error or, in layman’s terms, you’ve run out of Random access memory (RAM) to sustain the running of your code. This error indicates that you have loaded all of the data into memory. For large datasets, batch processing is advised. Instead of packing your complete dataset into memory, please save it to your hard disk and access it in batches.

If you’ve worked with other programming languages such as C or Java, you’re familiar with the concept of null. It is used in many languages to represent a pointer that doesn’t point to anything, indicate that a variable is empty, or indicate default parameters that haven’t been supplied yet. In such languages, null is frequently defined as 0, however null in Python is different.
