Where to place the import statements in Django?

Question

I have a lot of import statements in my views.py.

Does it help in terms of performance if instead putting all of the imports at the beginning of the file I put the imports in the views exactly where they are needed?

Having them in the particular view where they are needed helps also if you for example have to remove a view you don't have to scroll up and remove the unneeded imports.

No. If all imports will be placed at the beginning of the file, the import is performed only once - when the django-process starts.

And what if I put the imports in the view functions? Does this mean that the Python tries to import (but doesn't) every-time the view is called? – Al Bundy Oct 11 '12 at 19:28
If shortly: The module will be imported one time, but the function will be performed a little slower. See detailed answer here: http://stackoverflow.com/questions/128478/should-python-import-statements-always-be-at-the-top-of-a-module – defuz Oct 11 '12 at 19:33
