Hi,
Is it possible to convert a string to a function parameter?
Ex:
str = 'True, type=rect, sizes=[3, 4]'
and I should be able to use it as:
test(convert(str)) and the behaviour should be same as calling test
with those values :
i.e. test(True, type=rect, sizes=[3, 4])
I tried eval, but it did not work. And any other mechanism I think
turns out to be creating a full fledged python parser.
Is there any mechanism with which we can do this straight away?
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...)
The difficulty in writing such a function is that values don't have
unique names, if they have names at all. What should be returned in
these cases?
m = [654, 54, 65]
def function(m):
m2 = m
m3 = m[:]
takethenameof(m)
takethenameof(m2)
takethenameof(m3)
takethenameof(m[:])
takethenameof(2)
takethenameof(2+2)
There are samples online that try to do a "reasonable" job of this, but
my googling isn't turning them up...
