What happens when you downgrade a Django library?

Question

Django

People, what will happen in the virtual environment if there is a library, let's say django-url-filter version 0.3.0, and I will put django-url-filter version 0.2.0 on top. Will the previous higher version be overwritten or will they be installed together?
