Python Meta Programming

Question

I'm currently working on a rather big API project written in Python. I have a couple of endpoints, in each of which I want to perform more or less the same snippet of code. However, I don't want to copy paste it, and it is rather complicated to put it into an extra function as there are always a couple of context variables like loggers or requests. Is there some sort of meta programming mechanism in Python, that lets me "expand" / dynamically "write" code on runtime / interpretation time? I'm used to this from closure, so maybe some of you know what I'm talking about.

Here is an example:

# code I want in each function that uses x, y and local logger


def f(x, y):
  # reference to the above code

  # actual code of f

def g(x, y, z):
  # reference to the above code

  # actual code of g

I tried to use a decorator, but that does not seem clean to me, and it interferes with other decorators, if used like I did.

As a note, I'm writing purely sequential / functional code.

Thanks in advance!
