 Virtual environments are not just a feature of Python -

+most modern programming languages use a similar mechanism to isolate libraries or dependencies
+for a specific project, making it easier to develop, run, test and share code with others.
+Some examples include Bundler for Ruby, Conan for C++, or Maven with classpath for Java.
+This can also be achieved with more generic package managers like Spack,
