Like Juan says,
Read the documentation for modules and dictionaries and I think you will be
better off. However, here is a quick rundown of your questions:
AUTH_PASSWORD_VALIDATORS = [
{
'NAME': 'django.contrib.auth.password_validation.
UserAttributeSimilarityValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.
MinimumLengthValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.
CommonPasswordValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.
NumericPasswordValidator',
},
]
1. The first item in the list is the first dictionary that is present. A
dictionary in Python starts with a { and ends with a }. So the first item
is:
{
'NAME': 'django.contrib.auth.password_validation.
UserAttributeSimilarityValidator',
},
The AUTH_PASSWORD_VALIDATORS is a list of dictionaries with only one key
("NAME") and one item in them. So this is the first item and therefore the
first validator in this case.
2. Your assumption on dictionaries is wrong because "NAME" is not the
dictionary, but rather a KEY IN a dictionary (the entire first dictionary
is under bullet point 1 here).
3. The dot notation (as you call it) references a class that you can find
if you look in the django package, under folder contrib, folder auth, file
password_validation.py you will find a class class
UserAttributeSimilarityValidator. See the "dots" as directories / files
(they are modules).
So there is really not that much to explain here - it is probably simpler
than you expect it to be :-)

Andréas
