You are asking about self-modifying code, which is a terrible idea.

Siri uses machine learning, which is a difference concept.

Just write the function, and then call it.

If you write a function:

def foo(x):
   return x + 1


now you can use foo() like any other function, len(), str(), etc.


Have you done the Python tutorial? It sounds like you should consider doing
the tutorial.
