How to write a function to return the variable name?

Question

I want a function that can return the variable/object name as str like this :

Answer 1

Perhaps you can use traceback.extract_stack() to get the call stack, then extract the variable name(s) from the entry?

def getVarName(a):
    stack = extract_stack()
    print(stack.pop(-2)[3])

bob = 5
getVarName(bob);

Output:

getVarName(bob)
