I started a new job last year at a place that has a large percentage of their codebase in Python after many years of working with OO and relatively "modern" PHP. Of course, taking PHP's reputation online to heart, you can imagine my glee! To know that I would soon be working with a language that has a little more respect, clout, and professionalism!
Oh, how wrong I was.
One of the first things I noticed was the package management disaster, along with the virtual environment and local/global package issues. Just shy of a year later, and I'm absolutely flabbergasted that Python doesn't get utterly roasted online for how bad and fragmented some of the tooling is. I could go on about other frustrations I have with the broader Python ecosystem, but I'll just leave it at the point that Python folks shouldn't cast _too_ many stones in the direction of JS or PHP without knowing what the current state of tooling in those languages are.
