title: Given an instance of a type object, how do you call the constructor of the class (equivalent of GetConstructor in other languages)
body: <p>It seems simple, but I can't figure out how to get a class constructor if given only a type.
  For clarity I created a code snippet demonstrating the problem as a function stub.</p>
  
  <p>Google is not turning up anything useful, maybe I can't find the right keywords to avoid the SEO driving me to popular intro to python sites.</p>
  
  <pre><code>from typing import NamedTuple
  
  class Person(NamedTuple):
      name: str
      age: int
  
  def magic_thing_maker(the_type, ctor_args):
      pass # I am stuck with what to do here
  
  some_type = type(Person)
  the_person = magic_thing_maker(some_type, {'name':'Saul Goodman', 
  'age':37})
  
  assert (the_person == Person('Saul Goodman', 37))
  </code></pre>
  
  <p>Feel free to call my unpythonic for asking this; I get that asking this question indicates I should seek healthier approaches to the problem at hand.</p>
  
  <p>Any help much appreciated.</p>
