How to add authentication to a specific page in a dash application

I have a dash app with multiple pages.

I just want to prompt the use for an admin password when they try to access the /apps/exome route. is there a way to do that?

Flask-ImportError: ModuleNotFoundError: No module named 'mycode'

ImportError while loading conftest '/home/rohit/flask/src/tests/conftest.py'.
conftest.py:6: in <module>
from mycode import create_app
E ModuleNotFoundError: No module named 'mycode'
when running pytest form the src folder above mycode folder, it gives ModuleNotFoundError
The directory structure is as follow
├── mycode
│   ├── auth
│   ├── auth.py
│   ├── db_insert.py
│   ├── db.py
│   ├── __init__.py
│   ├── __pycache__
│   │   ├── auth.cpython-37.pyc

└── tests
├── conftest.py
├── data.sql

│   └── conftest.cpython-37-pytest-5.4.1.pyc
└── test_factory.py

Your __init__.py file needs to go in the folder named mycode. If the above is already true then try the following.
Rename __init__.py to mycode.py

What's the purpose of package.egg-info folder?

I'm developing a python package foo. My project structure looks like this:
.
├── foo
│   ├── foo
│   │   ├── bar.py
│   │   ├── foo.py
│   │   ├── __init__.py
│   ├── README.md
│   └── setup.py
├── footest
│   ├── test.py
test.py only has 1 line: import foo
In order for test.py to be able to import the package foo I install it with the command pip3 install -e foo.
Now a new folder called foo.egg-info is created under foo/
.
├── foo
│   ├── foo
│   │   ├── bar.py
│   │   ├── foo.py
│   │   ├── __init__.py
│   ├── foo.egg-info
│   │   ├── dependency_links.txt
│   │   ├── PKG-INFO.txt
│   │   ├── requires.txt
│   │   ├── SOURCES.txt
│   │   ├── top_level.txt
│   ├── README.md
│   └── setup.py
├── footest
│   ├── test.py
What's the purpose of this folder? I tried deleting it and test.py still ran properly. Is is just leftover garbage, similar to the .o files when compiling C projects? If so, is there a way to automatically remove it?

The package.egg-info saves meta data about your installed package like version.
It is used when you for example uninstall it, or "pip list" to see what is installed.
you can open it and take a look.

Why is pytest not running my tests and skipping them

I am using pytest-django to test my django application. My directory structure is like this :

The file : test_models.py is like below :
from django.contrib.auth import get_user_model
import pytest
#pytest.mark.django_db
class TestUserCreation:
def test_create_user_with_email_successfull(self):

assert user.email == email
assert user.check_password(password)
def test_new_user_email_normalized(self):

email = "test#GMAIL.COM"

user = get_user_model().objects.create_superuser(

assert user.is_superuser
assert user.is_staff
and the file : test_admin.py is like so :
import pytest
from django.contrib.auth import get_user_model
from django.urls import reverse
def test_something_simple():
names = ["Subhayan", "Shaayan"]
assert len(names) == 2

I am not sure what is wrong . Can someone please throw some more light on this . The pytest.ini file is as follows

PyCharm launching Django console for Flask app

For whatever reason, PyCharm thinks my Flask project is a Django project, and thus launches a Django console instead of a Python console in the toolbar:
The project interpreter is configured properly:

Just because there is a module called manage.py doesn't mean I'm working on a Django project!
How can I fix this?

You can disable Django support for your project here:
Settings > Language & Frameworks > Django
