Yes, the first one is a syntax error because you aren't allowed empty
parentheses in a class statement but the second one is a syntax error
because you don't have a colon.

sorry ,look at this :
class myClass:
class myClass(threading.Thread):

the former is a base class, the latter inherits behaviour from the
threading.Thread class.

*please* read the tutorial before proceeding.

however,

$ python
Python 2.5c1 /.../

>>class foo():

.... pass
....

>>foo

<class __main__.foo at 0x00A3D840>

If you don't know the answer to this, then it's time to read the fine
manual. Please come back when done.

seems like a feature/bug of 2.5, why your learning a language with a
beta version?

learning?

(btw, the "c" in 2.5c1 means *release candidate*, not "beta").
