python -m SimpleHTTPServer no longer working

python -m SimpleHTTPServer 8000 was working fine in order to render my web pages on localhost. When it quit, I used 7800, which also failed eventually, and now no numerical string works. For example, having launched the server using python -m SimpleHTTPServer 7600, I get the following when trying to render through the browser (any browser):
Serving HTTP on 0.0.0.0 port 7600 ...
127.0.0.1 - - [21/Feb/2022 20:14:04] code 404, message File not found
127.0.0.1 - - [21/Feb/2022 20:14:04] "GET /favicon.ico HTTP/1.1" 404 -
127.0.0.1 - - [21/Feb/2022 20:14:19] code 404, message File not found
127.0.0.1 - - [21/Feb/2022 20:14:19] "GET /FrontandBackMatter/css/style.css HTTP/1.1" 404 -
I get this result having changed nothing in the files.

Using Flask with Google App Engine Dev Server, swagger ui not found?

I am developing a website using Flask and Flask Restplus. I tried to use Google App Engine to deploy the app, however when I run dev_appserver.py on my computer, all the swagger-ui files cannot be found. I have no ideas why this happens? Can anyone tell me how to solve this?
Here is the example logs 404 for the resource:
INFO 2017-06-14 04:21:52,859 module.py:809] default: "GET /api/ HTTP/1.1" 200 3710

You need to put swaggerui inside your project. I suggest making a libs directory at the root of your project (same level as app.yaml).
Then, use GAE's vendoring method. To use vendoring, create (or modify) appengine_config.py in the root of your project, as follows:
from google.appengine.ext import vendor
# Add 3rd party libraries in the "libs" folder.
vendor.add('libs')

Flask can't find/run my app even though its in my Pythonpath

I have a very simple Flask app setup locally but when I try to run it I get this error:
NoAppException: The file/path provided (cowork_map) does not appear to exist. Please verify the path is correct. If app is not on PYTHONPATH, ensure the extension is .py
Im in a virtual env with flask and all other requirements installed and up to date, I have added the path to my project folder to my $PYTHONPATH and have checked that its there.
I have also used the second answer here to force check if its in my sys.path:
How to add something to PYTHONPATH?
I have tried force running it with 'python -m flask run' as advised here
Flask can't find app file
I ran export 'FLASK_APP=myapp.py' as advised in the official docs.
I have also tried running with with 'FLASK_DEBUG=1' and this is the output:
127.0.0.1 - - [05/Mar/2017 16:55:13] "GET /? __debugger__=yes&cmd=resource&f=style.css HTTP/1.1" 200 -

127.0.0.1 - - [05/Mar/2017 16:55:13] "GET /?__debugger__=yes&cmd=resource&f=console.png HTTP/1.1" 200 -
Whats even stranger is that I have another Flask project folder with its own env and that runs just fine, I can't see whats different with this one though.
I should add that everything in my app file is setup correctly with a Flask app initialized.
Also, if I run 'python -mflask run' (with DEBUG on) I get this error on the page when viewed locally:
__main__.NoAppException
but just 'flask run' displays this:
flask.cli.NoAppException

OK I figured this out, I have both Python 2.7 and 3 on my machine and there was a module I had imported that was installed on the other version of Python to the one I was using in my env. A very noob error I suppose!

Problems with Django static files

I have downloaded this project and trying to make it work: http://sourceforge.net/p/etconf/git/ci/master/tree/
The problem is, after I managed to install all prerequisites, it runs, but does not load staticfiles. According to settings it should look for them in the /media directory, but however I tried to change MEDIA_ROOT, STATIC_URL and various different parameters in settings.py it shows in the console:
[09/Oct/2015 10:56:08] "GET /static/configurator/admin/css/base.css HTTP/1.1" 404 2281
[09/Oct/2015 10:56:08] "GET /static/configurator/configurator.css HTTP/1.1" 404 2275
[09/Oct/2015 10:56:08] "GET /static/configurator/prototype.js HTTP/1.1" 404 2263
[09/Oct/2015 10:56:08] "GET /static/configurator/configurator.js HTTP/1.1" 404 2272
What am I doing wrong? Maybe it's some sort of old bug or something (project is using python 2 and django 1.1)

I guess you missed to run below command after configuration:
python manage.py collectstatic
What I see is you get 404 error for static files which means that the files are not located where it is been searched for.

Locally I dont have any problem with this but in deployment it gives alot of problem. My site totally becomes slow and throws internal server error..
Why I am getting this error

perhaps you forgot to runpython manage.py collectstatic on your server.
That dosen't affect the runserver command but the real webserver.
