My project tree is as simple as:
test
├── __init__.py (has line: "foo = True")
├── bar.py (has line: "bar = False")
└── test.py (has line: "from . import foo; from .bar import bar")
But none of the imports in test.py work. When I run python test.py, it returns: attempted relative import with no known parent package
Did I miss anything here? I am using python 3.7.6
the issue is arising because you are trying to import foo from __init__.py file as from . import foo , but to import from __init__.py file you need to use a parent folder module, ie from test import foo as how it is structured to import from __init__.py.
Your code is fine, but the test file needs to be imported as part of a package. So I created the following files and directories, exactly how you explained:
.
└── test
├── bar.py
├── __init__.py
├── __pycache__
└── test.py
From the parent of test, I ran this:
>>> import test
>>> import test.test
>>> import test.bar
>>>
It worked fine. But if you're doing relative imports, the code you're importing needs to be imported as part of a package, not executed as a standalone script.
If you're going to import files from the same folder you are, just use their file names:
bar.py
bar = False
foo.py
foo = True
test.py
from foo import foo
from bar import bar
print(foo, bar)
Running python test.py returns:
True False
Following the same/similar file structure, I can think of 2 ways to do imports:
Use absolute import if all three files are in the same directory level, so
test.py should look like:
import foo
import bar
and python test.py should run fine from the test directory.
Move foo.py and bar.py into a new directory, let's call it package, so the structure will be changed now to:
test/
├── package
│ ├── bar.py
│ └── foo.py
└── test.py
And test.py will be:
from package import bar
from package import foo
python test.py from the test directory will work.
