I was daunted by the complexities of projects when I started my data science career. We were using Virutalenv in all our Python projects.<\/p>\n\n\n\n
I’m impressed by the Node Package Manager (npm) and always wondered why we don’t have one like that in Python.<\/p>\n\n\n\n
\nI was yearning for a single tool to maintain isolated environments, manage dev and production dependencies, packaging, and publishing.Thankfully, we have Poetry now.<\/p>\n<\/blockquote>\n\n\n\n
In a nutshell, Poetry is a tool for dependency management and packaging in Python.<\/p>\n\n\n\n
But this official definition is incomplete because I found Poetry does more than manage dependencies and packaging.<\/p>\n\n\n\n
Poetry is not a substitute for virtual environments. It complements them with intelligent ways to manage environments and more.<\/p>\n\n\n\n
Here’s why I fell in love with Poetry at first sight.<\/p>\n\n\n\n
\n\n\nGrab your aromatic coffee <\/a>(or tea<\/a>) and get ready…!<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
Unlike Virtualenv, I can rename and relocate my project with Poetry.<\/h2>\n\n\n\n
Virtual environments are tied to a specific path. If I move or rename the project folder, the original path doesn’t change.<\/p>\n\n\n\n
I’d be in great trouble if I ever wanted to do it.<\/p>\n\n\n\n
Whenever I changed the path, I created a new virtual environment and installed packages.<\/p>\n\n\n\n
It was painstaking.<\/p>\n\n\n\n
Virtualenv has a
--relocatable<\/code> flag to help with it. But I’m not satisfied with this option either. Whenever I installed a new package, I had to flag the environment.--relocatable<\/code>.<\/p>\n\n\n\n
