I'm trying to limit a value stored by object (either int or float):
class Limited(object):
def __init__(self, value, min, max):
self.min, self.max = min, max
self.n = value
def set_n(self,value):
if value < self.min: # boundary check
self.n = self.min
if value > self.max:
self.n = self.max
else:
self.n = value
n = property(lambda self : self._value, set_n)
This works, except I would like the class to behave like built-in types, so
I can use it like this:
a = Limited(7, 0, 10)
b = math.sin(a)
So that object itself returns it's value (which is stored in a.n). Is this
possible?
Why not make it a function?
function assignLimited(value, vmin, vmax):
value = max(vmin, value)
value = min(vmax, value)
return value
a = assignLimited(7, 0, 10)
Seems like it solves your problem relatively cleanly.
Note: I also removed min/max variables because they would mask the built-in
min/max functions.
