ImportError: attempted relative import with no known parent package :(

Question

I'm attempting to import a script from my Items file but I keeps on getting an error

 from .Items.Quest1_items import *

gives

from .Items.Quest1_items import *
ImportError: attempted relative import with no known parent package

Process finished with exit code 1

Here my project tree, I'm running the script from the main.py file

Quest1/
|
|- main.py
|
|- Items/
| |- __init__.py
| |- Quest1_items.py

Answer 1

Remove the dot from the beginning. Relative paths with respect to main.py are found automatically.

from Items.Quest1_items import *

Answer 2

You can only perform relative import (ie., starting with a dot), inside a package that you import. For instance, imagine the situation:

project/
├ main.py
├ mylib/
├ __init__.py
│ ├ module1.py
│ └ module2.py

in main.py , you would have import mylib or from mylib import * , but inside module1.py , you could have from. import module2 from. import module2 , because here the . stands for mylib (which is a python package, because you imported it within main.py ).

So, the solution is simply remove the dot, it's not useful in your situation.

Answer 3

To put it simply: if you use relative import, you can run the file you want to run with 'python -m your_module_path' on the two layers above the outermost file used by your code.

Like the following, if you want to run run.py , you need to go to two layers above it, then run python -m dir1.dir2.run (without .py ).

.../dir1/dir2/
    -test
        -test1.py
            from .test2 import *
        -test2.py
    -run.py
        from .test.test1 import *
