Can You Retrieve Original Variable Names in Python Functions?

Retrieving Original Variable Names in Python Functions

In Python, it may seem desirable to obtain the original name of a variable when it is passed to a function. However, this task is not directly supported by the language.

To address this, one can leverage the inspect module, though it is not recommended due to potential drawbacks and drawbacks.

<code class="python">import inspect

def foo(a, f, b):
    frame = inspect.currentframe()
    frame = inspect.getouterframes(frame)[1]
    string = inspect.getframeinfo(frame[0]).code_context[0].strip()
    args = string[string.find('(') + 1:-1].split(',')

    names = []
    for i in args:
        if i.find('=') != -1:
            names.append(i.split('=')[1].strip())

        else:
            names.append(i)

    print(names)

def main():
    e = 1
    c = 2
    foo(e, 1000, b=c)

main()</code>

Output:

['e', '1000', 'c']

Important Notes:

• This method should be considered a hack and not used in production code.
• It can break in certain situations, such as when using nested functions or lambda expressions.
• There are alternative approaches, such as passing the variable name as an additional argument.
