I also tried to change ‘TA’ to ‘TA.apps.TAConfig’,but it did’t work too.

In your terminal where you are running your command python manage.py runserver there you can see if the environment directory is activated
something like this, here you can see `(env)` which is my environment folder where everything is installed for this particular project.
```auto
jlp-020@jlp020:~/Projects/POC-SingleVendor-BookanAppointment-BE$ source env/bin/activate
(env) jlp-020@jlp020:~/Projects/POC-SingleVendor-BookanAppointment-BE$
```
Note: I’m using ubuntu os, in windows there is different command to activate and even creating a virtualenv

When you [run your tests](https://docs.djangoproject.com/en/4.2/topics/testing/overview/#running-tests), the default behavior of the test utility is to find all the test cases (that is, subclasses of [`unittest.TestCase`](https://docs.python.org/3/library/unittest.html#unittest.TestCase)) in any file whose name begins with `test` , automatically build a test suite out of those test cases, and run that suite.
```python
def test_judgesex(self):
student=Student(sno='001',sname='ggg',sage=23,ssex='Male',sbirth='2000-09-19')
self.assertIsInstance(student,Student)
```
