Can You Print the Original Variable Names in Python After a Function Return?

Printing Variable Names in Python After Function Return

In Python, it is common to use enumerated variables such as myEnum.SomeNameA and myEnum.SomeNameB. When these variables are returned from functions, it can be useful to print their names rather than their values.

Short Answer: Not Possible

The short answer is that it is not possible to print the original variable names after they have been returned from a function. This is because Python variables are not objects that have names associated with them.

Long Answer: Hacky Workarounds

There are some workarounds that may allow you to achieve something similar, but these methods are generally not recommended for production code. One such workaround involves using the traceback, inspect, and other modules to access information about the call stack. This can be achieved using code similar to the following:

<code class="python">import inspect
import traceback

def get_variable_name(value):
    # Get the current stack frame
    frame = inspect.currentframe()
    # Get the function that called this function
    function = frame.f_back.f_code
    # Get the line number of the call
    line_number = frame.f_back.f_lineno
    # Get the source code for that line
    source_line = function.co_lines[line_number - 1]
    # Find the variable name
    var_name = source_line.split("=")[0].strip()
    return var_name</code>

However, it is important to note that such workarounds may be complex and error-prone, and they may not be suitable for all situations.

Workaround Alternatives

Instead of trying to print variable names, you could consider using a different approach based on your specific use case. For example, you could maintain a dictionary that maps values to their corresponding names or use a logging framework to record variable names along with their values.
