    Overview

When you're working on multiple coding projects, you might want a couple different version of Python and/or modules installed. That way you can keep each project in its own sandbox instead of trying to juggle multiple projects (each with different dependencies) on your system's version of Python. This intermediate guide covers one way to handle multiple Python versions and Python environments on your own (i.e., without a package manager like conda). See the Using the workflow section to view the end result.
Use cases


Working on 2+ projects that each have their own dependencies; e.g., a Python 2.7 project and a Python 3.6 project, or developing a module that needs to work across multiple versions of Python. It's not reasonable to uninstall/reinstall modules every time you want to switch environments.
If you want to execute code on the cloud, you can set up a Python environment that mirrors the relevant

                How to patch Polymer paper-dialog so appears in-front of its backdrop
              
          
    This howto is especially for when using a custom modal paper-dialog that is not within the <body> element - for example within a custom page element.
Add the following to your custom element:
// https://github.com/PolymerElements/paper-dialog/issues/7
patchOverlay: function (e) {
  if (e.target.withBackdrop) {
    e.target.parentNode.insertBefore(e.target.backdropElement, e.target);
 }
