At the writing time of this article Python 3. Our focus will be installing the core language tools that can be used in the command line. Once you get the hang of it, software collections are fairly easy to use. Any environment changes made in the parent after the child has been created will have no effect on the child. Will you get the same version of the modules you tested your code under? Python is simple and easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Using software collections requires an extra step because you have to enable the collection you want to use.
Note: your prompt has changed to show the virtual environment. Tip: If you need to work with Python 2. If you use a version number such as python3. This will show all software collections that are installed, whether they are enabled or not.
