python3-virtualenv - 20.17.1+ds-1 main

virtualenv is a tool to create isolated Python environments, each invokable
with its own Python executable. Each instance can have different sets of
modules, installable via pip. Virtual Python instances can also be created
without root access.
.
Since Python 3.3, a subset of it has been integrated into the standard library
under the venv module (python3-venv in Debian). The venv module does not
offer all features of this library, to name just a few more prominent ones:
.
* is slower (by not having the app-data seed method),
* is not as extendable,
* cannot create virtual environments for arbitrarily installed Python
versions (and automatically discover these),
* does not have as rich programmatic API (describe virtual environments
without creating them).
.
This is the Python 3 version of the library. It includes the command line
script.
