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.

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.

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.

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 bdist
$python bdist_wheel
$python sdist

To publish to PyPI, we may…

🆗 Now, let’s cut to the chase!

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