The second style is strongly discouraged. As Alan pointed out, it can lead to surprises when you import more than you expect. I was once surprised to find out that when I write something like a.py #### foo = 1 bar = 2 b.py #### from a import * c.py #### from b import * Now foo and bar are defined in module c!! The other reason to avoid this style is it removes clues about where a name is defined. If in module c above you want to know where foo comes from, it would be hard to find out. On the other hand if I wrote from a import foo then a search within c would show me where foo is defined.
