Question

In python, I want to make a class variable static so I can to use it from a different instance. is there any solution?

I don’t follow your question exactly, but it seems to me you’re asking how to make instance variables in Python. The answer is to set them inside a method, preferably __init__() using the self reference.

class Foo(object):
    classVar = 0 #this is a class variable. It is shared between all instances
    def __init__(self, instanceVar):
        self.someVar = instanceVar

obj1 = Foo(10)
obj2 = Foo(42)

print obj1.classVar # prints 0
print obj2.classVar # prints 0

print obj1.someVar #prints 10
print obj2.someVar #prints 42
