Accessing variable, stored in package's init from file in package

Question

I have a package named pkg and array named arr in __init__ file of this package. Also, I have file file.py in this package where I write from pkg import arr but it throws ImportError. How to import array properly?

Tree would look like this

pkg
- file.py
- __init__.py

__init__.py

arr = ['a', 'b', 'c']

file.py

from pkg import arr # ImportError raises here

print (arr)

Answer 1

__init__.py defines how your package looks from outside.

Try importing like this from . import arr, this basically means from current module import arr.

When asking about an error you should also provide the error message, ImportError is not enough. It could be a circular-import related error or a missing-library kind of error. The message usually helps a lot.

Answer 2

If you want to access the list arr in this manner. The file file.py should be in the base directory not in the package.

Hence the tree should be:

base
  - pkg   
    - __init__.py
  - file.py

Or, if you want to access the list from inside the package the import statement should be as the following:

from __init__ import arr
