[Harry Potter] Has anyone ever changed houses after their initial sorting?

I don't believe something like that is ever mentioned in the books. It would probably be a bad idea as your classes are largely sorted by Houses, as such a change in House would lead to a pretty radical change in timetable. Besides, there wouldn't be much point as a big theme in Deathly Hallows is that whatever House you are is not a true measure of your worth, i.e Snape was ultimately brave and passionate despite being a Slytherin and Wormtail was a sniveling coward despite being a Gryffendor.
