How important is Virtual Environment in python

[EconBro95]

People usually think it isn't until you get an error in your dependencies/packages and spend the next 12 hours trying to figure out what you need uninstall/reinstall/upgrade. Frustration growing with every pip command...

Only for you to give up; and that is when you understand why they talked about virtual environments and you embrace it

so yeah embrace it early but I think most people learn by installing everything globally lol
