It's generally not a good idea to use from module import *. Wildcard importing leads to namespace pollution; you imported more names than you need and if you accidentally refer to an imported name you may not get the NameError you wanted.

Also, if a future version of the library added additional names, you could end up masking other names, leading to stranger bugs still:

from foo import bar
from spam import *

If you upgrade spam and it now includes a spam.bar it'll replace the foo.bar import in the line above.
