I would like to import classes located into a folder named
some-dir/
and named class*.py
and finally instantiate them.
Wich is the best way to look inside the folder, import classes and instantiate them?

2What have you tried? Have you read about the import statement? Since this is what import does, I can't understand your question.S.Lott– S.Lott2009-06-11 16:22:39 +00:00Commented Jun 11, 2009 at 16:22

Try:
import os
#get files
files = os.listdir("some-dir/")
classes = []
for f in files:
#find python modules in file listing
if(f.find(".py") != -1):
#remove file extenstion
f = f.rstrip(".py")
#create string to add module to global namespace, import it and instantiate
#class
importStr = "global " + f +";import " + f + "; classes.append(" + f +"())"
#execute the code
exec(importStr)
That's a first stab at it. This assumes you don't have any parameters to pass to the class instantiation.
Don't know if it works, but it's somewhere to start. The "exec" statement lets you execute strings as python code.
Hope this helps you in the right direction.

Don't like the use of exec(), sorry
