Python3 : import

[Andrew Z]

this has bee driving me nutz for the past few hours.
2 modules are in the same directory. I want to be able to use them both:

[code]

[az at hp tst1]$ pwd
/home/az/Dropbox/work/Prjs/tst1

[az at hp tst1]$ ls -l
total 16
-rw-rw-r--. 1 az az  66 Jul  7 12:58 db.py
-rw-rw-r--. 1 az az 182 Jul  7 15:54 uno.py
[az at hp tst1]$ 
[az at hp tst1]$ 
[az at hp tst1]$ cat ./db.py 

class DB():
	def __init__(self):
		print("I'm DB")

[az at hp tst1]$ cat ./uno.py 
from . import db

class Uno():
	def __init__(self):
		print("I'm uno")
		self.db = db.DB()

	def printing(self):
		print("Uno.printing DB")


if __name__ == '__main__':
	uno = Uno()

[az at hp tst1]$ 
[az at hp tst1]$ 
[az at hp tst1]$ python3 ./uno.py 
Traceback (most recent call last):
  File "./uno.py", line 1, in <module>
    from . import db
SystemError: Parent module '' not loaded, cannot perform relative import

[/code]


Much obliged.
