Firstly, in Python circles we prefer to call them "attributes" rather 
than variables.

Since this is Python, it is trivially easy to test this for yourself. 
Start an interactive Python interpreter, and then in under a dozen lines 
you can test it:

py> class Test:
...     attr = "Hello World!"  # Shared class attribute.
...
py> class MyTest(Test):
...     pass
...
py> x = MyTest()
py> x.attr
'Hello World!'


Works perfectly! (It would be a funny programming language where it 
didn't, since this is one of the most fundamental parts of inheritance. A 
language that didn't do something equivalent to this couldn't really 
claim to be object-oriented.)
