Type conversion issue while using Descriptor in Python3

[mailnsuresh]

This is a little tricky one. Needs more attention since it is a minute thing. There are two classes in the given code. 'celsius' attribute of temperature is handled by 'Celsius' descriptor. Requirement is to have temperature maintained in both fahrenheit and celsius. When executed the code below, as per my understanding, the output should be

32 0.0
32.0 0.0

but the one we get is

32 0.0
32 0.0

Can anyone help me understand why the fahrenheit value in the second line is still an 'int' eventhough it is converted into 'float' in the __set__ method in the descriptor class?

#!/bin/python3   import sys import os   class Celsius():     def __get__(self, instance, owner):         return float(self.__celsius)     def __set__(self, instance, value):         self.__celsius = value         self.__fahrenheit = float(value * 9/5 + 32)   class Temperature():     celsius=Celsius()     def __init__(self,fahrenheit):         self.fahrenheit=fahrenheit         self.celsius=(fahrenheit-32)*(5/9)   t1 = Temperature(32)[size=medium][/size] print(t1.fahrenheit, t1.celsius) t1.celsius=0 print(t1.fahrenheit, t1.celsius)

This should point out the problem. You are not seeing Celsius.__Fahrenheit

1 2	t1.celsius=10 print(t1.fahrenheit, t1.celsius)

Output:
32 10.0

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

class Temperature():     def __init__(self, fahrenheit):         self.__fahrenheit = fahrenheit       @property     def celsius(self):         return (self.__fahrenheit - 32) * 5/9       @celsius.setter     def celsius(self, value):         self.__fahrenheit = value * 9/5 + 32        @property     def fahrenheit(self):         return self.__fahrenheit       @fahrenheit.setter     def fahrenheit(self, value):         self.__fahrenheit = float(value)   t1 = Temperature(32) print(t1.fahrenheit, t1.celsius) t1.celsius=10 print(t1.fahrenheit, t1.celsius)
