Return the variable value as string in python

Question

Suppose I have two variables:

_first = True
_second = _first

print (getValue(_second))

>>> _first

Is there a way to implement getValue(or anything else) in that way ? I don't care about the real value (boole\int\string etc..) , just the name of the assigned variable.

Thanks

Variables don't refer to each other. When you use _second = _first, you aren't making _second refer to _first, you're making it refer to the value that _first refers to. This might clear some things up: Facts and Myths about Names and Values in Python.

Nice link, Ned! And it's nice to see you having fun with good old Graphviz. :) (FWIW, I programmed in various "traditional" languages (including C) for many years before coming to Python, but I'd learned about the binding approach to variables via PostScript, so I adapted to Python fairly quickly).

No; once you've assigned _first to _second, there is no longer any connection between _second and where it got its value from (as opposed to the value itself).

you cannot print out the variable's name in such a way.

But you might try using Dictionary so that you can have a key-value pair for each entry.

That way you can find the values corresponding to certain names as keys and get the key names as well. I hope that helps you.

to get help on dictionaries you can refer:
