Instantiate a Python class from a name
Question: So i have a set of classes and a string with one of the class names. How do I
instantiate a class based on that string?

    
    
    class foo:
      def __init__(self, left, right):
         self.left = left
         self.right = right
    
    str = "foo"
    x = Init(str, A, B)
    

I want x to be an instantiation of class foo.


Answer: In your case you can use something like

    
    
    get_class = lambda x: globals()[x]
    c = get_class("foo")
    

And it's even easier no get class from the module

    
    
    import somemodule
    getattr(somemodule, "SomeClass")
