this is great, but do you have a logical explanation why is the TEMPLATES setting is like this?

TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [
os.path.normpath(os.path.join(BASE_DIR, 'templates')),
],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request', => # "same as below"
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
'django.template.context_processors.request', => # "same as above"
],
},
},

]

is this necessary?
why not like this?
for it's more simple and understandable
