It's in the "tmp" module, where you defined it. But because you didn't
ask for a reference to it in your import statement, it's not
accessible to you[1].
Do
import tmp
print(tmp.a)
and you can see it.

[1] Technically you can find it via the globals of the function test,
as test.__globals__['a'], but if you understand how that works, you
wouldn't have been asking the question in the first place :-)
