How Can I Determine the Name of the Calling Method in Python?

Finding the Caller's Method Name in Python

In object-oriented programming, methods can often call other methods on the same or different objects. In situations where a called method requires information about its caller, obtaining the caller's method name can be valuable.

Identifying the Problem

Consider the following Python code:

In this example, we have two methods, method1 and method2. Assume we want to obtain the name of the caller of method2 from within that method itself. Specifically, we want to determine that method1 is the caller.

Unveiling the Solution Using Introspection

Python provides the inspect module, which offers introspection capabilities. Here's how we can leverage it to achieve our goal:

By calling inspect.getouterframes(frame, 2), we obtain a list of outer frames representing the call stack. The second frame in this list corresponds to the caller of method2, which, in our case, is method1. The fourth element in each frame tuple represents the method name, which we print to the console.

Cautions

While introspection can be useful for debugging and development, it's not recommended to rely on it for production-critical functionality.
