Can't we do the same thing with python, flask? Yes, not compiled and strongly typed but it's still easy to instantiate a web server with a few lines of code, no?
It's going to be a lot less performant, but yes Python has a lot of library support as well and you can create a web basic web server with relatively little code. Go's HTTP stack though is part of the standard library while flask is not (there might be some standard library equivalent though).
Some people move to Go from Python for performance reasons (and other reasons).
