import { BrowserRouter as Router, Route, Switch } from 'react-router-dom' What is the relationship between Router, Route, Switch and BrowserRouter? Is this a form of destructuring? If so, I thought destructuring was done using the following syntax:
Should I use from foo import bar OR import foo.bar as bar when importing a module and there is no need/wish for changing the name (bar)? Are there any differences? Does it matter?

I was able to import this certificate into a keystore by first stripping the first and last line, converting to unix newlines and running a base64-decode. The resulting file can be imported into a keystore (using the keytool command).
You can theoretically import all variables and functions with from os.path import *, but that is generally discouraged because you might end up overwriting local variables or functions, or hiding the imported ones. See What's the difference between "import foo" and "from foo import *"? for an explanation.
