How to override an old sqlite3 module with pysqlite3 in django settings.py

settings.py

# ⚠️ USE AT YOUR OWN RISK
# first: pip install pysqlite3-binary
# then in settings.py:

# these three lines swap the stdlib sqlite3 lib with the pysqlite3 package
__import__('pysqlite3')
import sys
sys.modules['sqlite3'] = sys.modules.pop('pysqlite3')

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

This gives the error
NameError: name 'sqlite3' is not defined

import('pysqlite3')
import sys
sys.modules['sqlite3'] = sys.modules.pop('pysqlite3')
