I don't know if it's the same in general, but consider the following
sequence in 2.6:

import sys

class MyClass(object):
    pass

print "class--", dir(MyClass)
print "module--", dir(MyClass.__module__)
mod = sys.modules[MyClass.__module__]
print mod
print "globals--", dir(mod)

Excellent!  Exactly what I wanted, but wasn't clever enough to figure
out for myself.  Thank you very much.


But dir(mod) gives you only names, not objects (though, of course, you
can get them "manually" with getattr(mod, name)). To get from a class
the same you get from function using func_globals (i.e. dictionary with
names as keys and objects as values), use:

mod = sys.modules[MyClass.__module__]  # (as above)
vars(mod)  # or mod.__dict__, though vars(mod) seems to me more elegant

Cheers,

class version of func_globals?

Is there any way to get the global namespace of the module in which a
class was defined?  Answers for both Python 2.x and 3.x will be
cheerfully accepted.
