VS Code Python import module doesnt work ModuleNotFoundError: No module named 'words'

In VSCode I try to import module but there is the error: ModuleNotFoundError: No module named 'words'
screenshot from VS Code
Any advice? Thanks

You need to run your script, Untitled-1, in the same directory as words.py file. The import statement looks for modules on PATH and in the current directory. Mind that currently your words.py are located deep in AppData directory, which is likely not the best place to stash project files.

Put this two .py files into a folder, then open the folder in VS Code. You can import it successfully:
The folder pycache is generated after you run the file successfully.

Python test script works when using -munittest, but fails due to ModuleNotFoundError when ran directly

I've got a test script which imports modules from my application. This works when run with python -munittest, but it fails with ModuleNotFoundError if I simply use python tests/test_app.py.
This also happens with other scripts in this project which aren't unit tests.
$ python tests/test_app.py
Traceback (most recent call last):
File "tests/test_app.py", line 2, in <module>
import myapp
ModuleNotFoundError: No module named 'myapp'
$ python -munittest tests.test_app
....
----------------------------------------------------------------------
Ran 4 tests in 0.119s
OK
As you can see from the trace, it fails at the very beginning of the file, in the imports, where I use import myapp.
Project structure:
/project
/myapp
__init__.py
models.py
/otherapp
/anotherapp
/tests
test_app.py
/scripts
a_script.py
What magic is the unittest module doing to make my script load?
How do I execute my script directly?

It fails because when you run with python tests/test_app.pyyour python will look for myappin the local folder relative to the test_app.py or in PYTHONPATH and won't find it. Whereas unittest will handle importing the package while starting from project root folder.
This python documentation link explain how import statement work
When a module named spam is imported, the interpreter first searches
for a built-in module with that name. If not found, it then searches
for a file named spam.py in a list of directories given by the
variable sys.path. sys.path is initialized from these locations:
the directory containing the input script (or the current directory).
PYTHONPATH (a list of directory names, with the same syntax as the
shell variable PATH).
the installation-dependent default.
After initialization, Python programs can modify sys.path. The directory
containing the script being run is placed at the beginning of the
search path, ahead of the standard library path. This means that
scripts in that directory will be loaded instead of modules of the
same name in the library directory. This is an error unless the
replacement is intended. See section Standard Modules for more
information.
Therefore, to make your script directly executable you need to tell python to find "myapp" using one of the ways described in the documentation. Here's another SO question discussing how to use import (you can find a lot more with a quick search).

ImportError: No module named … error in Python - set PYTHONPATH still not working

I have a problem similar to that described here How to fix "ImportError: No module named ..." error in Python? but I cannot fix it with the suggestion to set PYTHONPATH.
my directory looks like:
- project
- python
- src
- ml
- __init__.py
- classifier_dnn.py
- util.py
- vectorizer
- fv_davison.py
- __init__.py
And I am running classifier_dnn.py at the project folder path:
~project&PYTHONPATH=/home/project/
~project$python3 /home/project/python/src/ml/classifier_dnn.py /home/project/data/labeled_data_all.csv /home/project/output
But an error is generated when classifier_dn imports ml.util:
Traceback (most recent call last):
File "/home/project/chase/python/src/ml/classifier_dnn.py", line 5, in <module>
from ml import util
ImportError: No module named 'ml'
I have also tried setting PYTHONPATH=/home/project/python or PYTHONPATH=/home/project/src but the same error happens.
When I test this in PyCharm, it works if set python/src to become source root, regardless what working directory is. But I cannot figure out how to set this properly when I run this from command line.
Any help please
Thanks

I have a writeup on this but I'll copy the relevant text inline.
You have two problems:
You need to export PYTHONPATH (export PYTHONPATH=/full/path/to/src)
You should run with python -m module.path instead of python path/to/file.py
The core problem is python path/to/file.py puts path/to on the beginning of the PYTHONPATH (sys.path)
This causes imports to start from (in your case) src/ml instead of the expected src.
By using -m, you avoid this path munging and it will correctly keep src as the beginning of your sys.path.
When I test this in PyCharm, it works if set python/src to become source root, regardless what working directory is. But I cannot figure out how to set this properly when I run this from command line.
You can do this by cding into the src directory

You should not put executable scripts into a library structure.
Only library modules should go into the package structure. Executables should stay outside it. This is important for installation and day-to-day use. Once you have installed your package (using distutils for example) using it would be complicated, if you leave the executable in the library. You would have to give the complete installation path into the python library (and don't forget about -m!) every time or create shortcuts or other workarounds.
Seperate executables and library. Executables are installed to something like usr/local/bin and are callable without path, -m or other problems, and your library is installed into the python library.

__init__ file doesn't work as expected in python

I have some folders and .py files in the following structure:
parent/
__init__.py
test.ipynb
code/
__init__.py
common.py
subcode/
__init__.py
get_data.py
In the __init__ file under the parent folder, I have import code and in the one of code, I have import subcode. But when I tried import code.subcode, I got such an error:
ImportError: No module named 'code.subcode'; 'code' is not a package
But when I just import code, no error is thrown. However, when I call code.subcode, this error happens:
AttributeError: module 'code' has no attribute 'subcode'
I try all of those mentioned above in the test.ipynb, which is at the root of the directory.
Do you know what is the reason and how can I fix it? Thanks!

The problem is that you are importing another module named code that is installed on your system rather than your own module. You can verify this by checking the module file path in code.__file__ after you import code.
The first thing to do is change the name of your module to avoid namespace collisions with the other code package on your system. If your new package name doesn't collide with something else, you should now either successfully be importing it and have it behave as expected, or it fails to import entirely.
If it fails to import, it is most likely because your parent directory is not in your PYTHONPATH environment variable.
There can potentially also be other more technical reasons that a module is not recognized by the interpreter such as old definitions being cached (in which case restarting the interpreter is often enough. Possibly after deleting any precompiled versions of the module). Another problem I have seen ended up being that a module contained a bug that made the interpreter unable to parse it. I am sure there are other odd possibilities out there.

You're on Python 3. You need to perform relative imports explicitly:
from . import code
The code module you're currently getting is the standard library code module.

Python - ImportError

I have a module I have installed called lts_fits, and this is its path:
~/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/lts_fits
So it is clearly in the site packages folder. Within this folder, there is a python script:
lts_linefit.py
Yet when I have this line of code in my script:
from lts_fits import lts_linefit
I get this error:
ImportError: No module named lts_fits
How? It's clearly in there, and I have tried this same syntax with other random scripts and they import just fine. For instance, a file abc.py located in the folder ~/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/sympy imports just fine when I have the line from sympy import abc. What could be going wrong?

You need an __init__.py file in that directory (you do not have to put anything into the file, all you need to do is create it).
The easiest way to create said file is by using:
touch __init__.py
from within your lts_fits directory in your command line/terminal/console.
See this SO article: What is __init__.py for?
And the Python Documentation for packages.
