python如何将变量名作为字符串输出

import inspect

def retrieve_name(var):
“”"
Gets the name of var. Does it from the out most frame inner-wards.
:param var: variable to get name from.
:return: string
“”"
for fi in reversed(inspect.stack()):
names = [var_name for var_name, var_val in fi.frame.f_locals.items() if var_val is var]
if len(names) > 0:
return names[0]
