Not really. But, why not create an instance of some custom type in x.py, and 
import that instance into the current namespace? Just as convenient.

x.py
----
mylist = {"one":1,"two":2}
class test(object):
    def __getattr__(self,name):
        return mylist.get(name,None)
test = test()
---

y.py
---
from x import test
print test.one
print test.two
print test.three
