Help with Regex for domain names

I'm trying to figure out how to write efficiently write a regex for
domain names with a particular top level domain. Let's say, I want to
grab all domain names with country codes .us, .au, and .de.

I could create three different regexs that would work:
regex = re.compile(r'[\w\-\.]+\.us)
regex = re.compile(r'[\w\-\.]+\.au)
regex = re.compile(r'[\w\-\.]+\.de)

How would I write one to accommodate all three, or, better yet, to
accommodate a list of them that I can pass into a method call? Thanks!
