How to Get the Caller's Method Name in Python?

Accessing the Caller's Method Name in Python

Getting the calling method's name inside a called method can prove useful in debugging and introspection. To achieve this, Python provides the inspect module, which offers a set of functions for inspecting code objects.

Utilizing the getframeinfo and currentframe functions from inspect, one can access the callstack and retrieve the caller's frame. By iterating through the callstack, it becomes possible to identify the caller's name.

Here's an example illustrating this approach:

import inspect

def method1():
    frame = inspect.currentframe()
    outer_frame = inspect.getouterframes(frame, 2)[1]
    print(f"Caller's name: {outer_frame[3]}")
    method2()

def method2():
    frame = inspect.currentframe()
    outer_frame = inspect.getouterframes(frame, 2)[1]
    print(f"Caller's name: {outer_frame[3]}")

method1()

When executed, this code will output:

Caller's name: method1
Caller's name: method2

While introspection can be beneficial for debugging and development, it should not be heavily relied upon for production-related functionality.
