They did share it, until you assigned an instance variable in b, which
shadowed the class variable.  Example:

>>> class Test1:
	myInt = 4

	
>>> a = Test1()
>>> b = Test1()
>>> a.myInt
4
>>> b.myInt
4
>>> Test1.myInt
4
>>> b.myInt = 3
>>> a.myInt
4
>>> b.myInt
3
>>> Test1.myInt
4

As soon as you bound the name b.myInt to a new value, it created an
instance variable.  That hides the value of Test1.myInt.
