Motivation:

Security in your code is considered to be of paramount importance today, especially when we work remotely. We do a lot of proof-of-concepts, implement business logic with multiple libraries. Though most of them are open source, there could be vulnerabilities, license issues when we productize the code for commercial use. It is almost impossible to keep an eye on every single library and their possibility for commercial use. That’s why we have vulnerability scanners to make lives easier.

Motivation

Recently, I was given a task of refactoring our legacy command line application. I was thinking what more could we do to improvise a legacy command line application that’s working just fine.

Remembering the commands and their respective flags, optional parameters etc is bit hectic. Of course you could copy all the commands in a notepad and use ’em as needed. But that’s still annoying if you ask me.

So what did I do?

I came across this library called PyInquirer and rich with which we could make colorful command line applications that are interactive.To …

Objective

Do you want to get over the regular monochrome command line? Interested in building visually appealing clis? …Or want to showcase your cli with cool enhancements? If you have any of these on your mind, then you should definitely try using python’s rich library.

Support

Rich works on OSX, linux and windows platforms

Python:

≥ Python 3.6.1

Installation

pip install rich

Introducing rich

Rich is a Python library for writing rich text (with color and style) to the terminal, and for displaying advanced content such as tables, markdown, and syntax highlighted code.

Getting started

Without further ado, let’s start using the commands of the rich library…

Introduction

I hope we all are familiar how plain Python classes work and their use cases. Python also provides an indirect way to implement immutable classes using namedtuples. Wait, why are we talking about namedtuples here? Well, there is a reason why I am talking about them here.

For people, who are new to namedtuples please have a look here to understand more about it and it’s applications.

How namedtuples can be used to store attibutes like classes

A namedtuple is a container provided as part of the collections module which has the same properties as a tuple. The only difference is we can access the members of a namedtuple using…

Introduction:

Pip has been the package installer for Python libraries for a long time. However, pip has a few limitations. We don’t have a single solution to download, install, package, build and publish in Python.

Revisiting setuptools:

Traditionally we download and install dependencies using pip in Python. However, we have to rely on setuptools to build and distribute packages in Python.

We use the following commands to build a source distribution/binary distribution or a wheel file.

$python setup.py bdist
$python setup.py bdist_wheel
$python setup.py sdist

To publish to PyPI, we may have to use twine. As just discussed, we don’t have a one-stop…

Introduction:

The most common mistakes we make in interviews are the most silly ones. Do you agree? This happens because we ignore the ones which we are quite familiar. During interviews, we prepare the most difficult data structure and algo questions and seldom give importance to fibonacci or prime number programs. However, sometimes we get stuck during interviews in these petty programs. This article is a refresher for fibonacci series generation using python.

🆗 Now, let’s cut to the chase!

Fibonacci Series:

A Fibonacci series or number is the sum of preceding 2 numbers starting from 0 and 1. …

Introduction:

pip is the package manager for python.pip can be used to install python libraries from PyPI. In other words, pip is the npm of python. We use pip to install and manage python libraries that are not part of the python standard library.

Motivation:

Any python developer predeminantly uses pip day in and out.However, the usage is limited to just install and occasionally upgrade.

This article is a consolidated non-exhaustive list of all the pip commands every python developer should know. This could be a reference for any future pip commands.

Commands:

Install — plain install:

The install command is used to install the specified library…

Introduction:

Any Python application has to be packaged for a user to use it. Why package your application? Firstly, you may not want to expose your code directly to the customer. Secondly, your end-user may need a single executable or a binary file to use your application rather than digging along the script files.

Briefcase:

If you have been working as Python developer for a while now, I am pretty sure you would have packaged your application into a binary or an installable file.The most common libraries we use are pyinstaller, cx_freeze, py2exe etc. Although pyinstaller is relatively more prevalent.

We have…
