Running Command Prompt In Python
by Am Ra Feb. 29, 2024

Feb. 29, 2024

Hi, I am trying to activate and run command prompt in python but I am stuck in one section of the code. Below I will explain what I have done so far and what issue I am dealing with. Importing os, and using os.system to connect to Command Prompt. [image: image.png] Then, dmel922.exe will be activated to generate an empty csv file from a raw dataset. [image: image.png] Up to here it is working as it is supposed to. However, it goes on a pause and not adding any data to the empty csv file because it is waiting on the user input which is “Enter y to Continue”. As we see in the picture below, the Command Prompt is asking the user to press y to continue. As soon as, I press y in the Command Prompt it will continue and finish the task. [image: image.png] I just cannot figure out how to write a code in python to answer that “Enter y to Continue” prompt or bypass that so that the system continues and finishes its task. Please advise. Thank you very much. Sincerely, Mike

file accessibility across directories?
by James Hartley Feb. 29, 2024

I am having issues with accessing files across different directories. The file structure I am using is simple: +-project | +- .git +-src | | | +- foo.py | +- bar.py | +- tests | | | +- test_foo.py | +- utils | +- baz.py Test files within project/tests reference classes successfully in foo.py through Pytest as: from src.foo import Foo Pytest is actually executed from the ./project directory successfully as: python -m pytest -v tests/test_foo.py baz.py had been in the src directory, where it successfully referenced class Foo as: from foo import Foo Now baz.py has been moved to utils/baz.py. I would think that this would require the import statement to changed to: from src.foo import Foo ...but I receive a "ModuleNotFoundError: No module named 'src'" error. I have tried adding an empty src/__init__.py file which doesn't change the error received. I always invoke the Python interpreter from the project directory. Always. The ./project/tests directory does not have a __init__.py file present. To date, I have not required this file anywhere, so I have not created it. Any insights shared which can help me resolve this simple issue would be appreciated.

Regarding importing from a sub-directory

There's no need Alan, to post either of my previous messages to the list. I have discovered the answer to the problem. It's IDLE that's the problem. VS Code does not have a problem importing from a sub_directory. -- Regards, Phil

Importing a class from a sub-directory
by Phil Feb. 10, 2024

Thank you for reading this and this is a problem that I've struggled with for quite some time. The simple fix was to copy myclass into whatever project directory that I was working on at the time, but of course, this means that I have to maintain multiple copies of the same class. Say I have myclass.py saved in ~/Python and I want to import myclass into myproject.py that is saved in ~/Python/Tkinter/myproject. How do I do that? I have tried countless possibilities including: from ..myclass import Myclass I've created a file named "__init__.py and saved myclass.py into that file I've tried from "~/Python/myclass" import Myclass but that's a syntax error I've scoured the Internet looking for a solution and read several tutorials and even consulted my AI friends and I'm still at a lose to solve this seemingly simple problem. Using the tree command I have confirmed that I have the following directory structure: ~/Python |__ myclass.py |__ Tkinter |_ myproject.py -- Regards, Phil
