How to retrieve source code from Python objects?

To retrieve source code from a Python object, you can use the inspect module. Specifically, you can use the getsource() function to return the source code of a given function.

Here’s an example:

import inspect

def my_function():
    print("Hello world!")

source_code = inspect.getsource(my_function)
print(source_code)

This code defines a function called my_function() and then uses the getsource() function from the inspect module to retrieve its source code. The output of the code will be:

def my_function():
    print("Hello world!")

You can use this technique to retrieve the source code of any function or class in your Python code.

Note that the getsource() function will only work if the source code is available. If your Python code is compiled or packaged in a way that makes the source code unavailable, you may not be able to retrieve it using this method.
