can't call an existing function from python shell

I have a python/django project, with a django app called "testApp". under "testApp" I have a python file: "hello.py". The file reads:

class Hello():
  def sayHello():
    print ("hello")

How can I activate the sayHello function from python manage.py shell

importing "testApp" doesn't help as calling "Hello.sayHello()" gives out an undefined error.

What am I doing wrong?

You need to import the actual name you want to use. Just importing testApp won't do anything; you would need to do from testApp.hello import Hello.

Note also that since for some reason you have a class, sayHello is an instance method and therefore needs to accept the self parameter; also, you would need to instantiate the class before calling the method. However, Python is not Java, and there is absolutely no need for the Hello class to exist.
