I was going to ask this for ages now.
For example we've got a controller.
import os
class MyController(BaseController):
def do_stuff():
import os
os.open(...)
def do_more():
import os
os.do(...)
The question being, what's the best practice here for this exactly in
pylons.
When the server is launched, the top level import is done, making it
availible for everyone in the module.
If I'll only import os in the method, won't it cause more work to
import it every single time the method is run?
On the other hand, won't it probably be more efficient to import only
for the time, the method that actually uses this import works and then
(i believe) garbage collection will free the memory until the next
time it'll be used.
I do understand that this question is only loosely related to pylons,
but I'm new to python and don't know know where I can find this low
level behaivior explained, especially in relation to Pylons and WSGI
apps.
If there're sources out their, I'd really appreciate if you'll point
me their. I'd love to rtfm :)
Thanks a lot!
