confusing about running some codes in django

Hi . 
when i read the django docs,it suggested that running some code but it does not note that where to write this piece of code . the code is :

from django.contrib.auth.models import User

u = User.objects.get(username='john')
u.set_password('new password')
u.save()

i know that i can run it in django shell (manage.py shell)
but i want to write these in a file(its some confusing that every code in views.py should return a http response but this type of commands does not return any respone) 
where should i put this code ??
thanks for your attention.
