class Domin():
def __init__(self , a, b) :
self.a=a , self.b=b
def where(self):
print 'face : ' , self.a , "face : " ,self.b
def value(self):
print self.a + self.b
d1=Domin(1 , 5)
d1=Domin(20 , 15)
I get this error:
Traceback (most recent call last):
File "test2.py", line 13, in <module>

self.a=a , self.b=b
TypeError: 'int' object is not iterable
Declaring multiple variables in a single declaration can cause confusion regarding the types of the variables and their initial values. If more than one variable is declared in a declaration, care must be taken that the type and initialized value of the variable are handled correctly.
You can assign the same value to multiple variables by using = consecutively. This is useful, for example, when initializing multiple variables to the same value. It is also possible to assign another value into one after assigning the same value.
You cannot put two statements on one line like that. Your code is being evaluated like this:
self.a = (a, self.b) = b
Either use a semicolon (on second thought, don't do that):
self.a = a; self.b = b
Or use sequence unpacking:
self.a, self.b = a, b
Or just split it into two lines:
self.a = a
self.b = b
I would do it the last way.
