I need the exact opposite, what is the inverse function?
example: i pass to a function an argument

m=[654,54,65]
def function(m):
    return takethenameof(m)

and it have to return to me 'm' not [654,54,65] or '[654,54,65]'

anybody can help?
i think that when one is talking about a function he have to talk also of the inverse function (also because google have problems searching about this...)
