It solves more than that:

- beginers don't have to understand the whole virtualenv shenanigans. I use pew myself to replace virtualenvwrapper but I will switch to pipenv just to ease the pain of team member joining in.

- it enforces good dependency management practice with the toml file and lock file. This is an issue in almost all project I worked on, including ones from Python experts. We all use only requirements.txt file out of convenience, and never lock.

- it's one tool to do all the packaging stuff. No need for pip and virtualenv and a wrapper. You got one command.
