Because you defined a in your current file.
You need to define it in features.

So you need to define a in features.
Note that if you define a in features to be an empty list you can 
add/delete items to that list from the importing module.

########## features.py##########
a = []

###########main.py##########

import features
print features.a

features.a.append(66)
print features.a

features.a.remove(66)
print features.a


Does that help?

NB. I don't really recommend this approach, but it is a way 
to do what I think you want...
