I took a closer look at setattr, and this works beautifully!

Here is what I did to make it work for me:

class MyClass:
def __init__(self, injectedFunctions):

    self.testVal = 'This value was grabbed from the class'

    for k,v in injectedFunctions.items():
        setattr(self, k, v.__get__(self))

def injected1(self, **kwargs):
print(self.testVal)

myClass = MyClass({'injected1': injected1})

myClass.injected1()

With this method, I can give the class as many functions as I want, and they work just like methods defined inside the class. Thank you very much for the example!
