[edit] This question doesn't realy make sens and this situation could be avoided, being caused by a lack of effort from my part. Feel free to downvote to close.

I have two files : file0 which has a object Obj containing variables and file1 which needs these variables. Here is the code:

file0 :

class A :
    def __init__(self) :
        self.v0 = 0
        self.v1 = 1
Obj = A()

file1 :

from file1 import Obj
v0 = Obj.v0
v1 = Obj.v1
del Obj
print(v0, v1)

Is there a more efficient way to do this. I have tried from file0 import Obj.v0 as v0 and from file0.Obj import v0 but I get errors for both. Would someone now a better solution ? By better I mean a solution that imports directly v0 and v1 without Obj. I prefer not to declare Obj in file1 because file0 is the main file doing most of the logic, but file1 needs to acces them. I cannot just use a variable in each file that I declare with the same value. I could merge the two files but for readability reasons, it wouldn't be practical.

• python
• import
• python-import

• 3 Doing any of this in the first place seems a little weird. The better solution is probably to not do this, and instead find a different way to approach whatever underlying problem this design was supposed to solve. – user2357112 Commented 14 hours ago
• I'm voting to close this question as it lacks clarity: What objective criteria determines if a solution is "better"? – InSync Commented 14 hours ago
• 1 Was this an attempt to avoid global variables? It seems like the kind of thing someone might come up with if they heard global variables are bad, but didn't hear why they're bad. – user2357112 Commented 14 hours ago
• 1 In that case, this sounds like an XY problem (as also have been pointed out by user2357112 above). Why would you want to do this? – InSync Commented 13 hours ago
• 1 Obj = A() should happen in file1 not file2. – JonSG Commented 12 hours ago

It depends on what you need. Remember that ALL of the names in an imported file are available, so you COULD do:

# file0.py
v0 = 0
v1 = 1

# file1.py
from file0 import v0, v1
print(v0,v1)

Is that better? Well, it depends.
