But i don't understand complete.

I want to log user (with username or email and password)

log user means you want to create a log file and login means something else. I don't understand if you are saying log the user or login the user? — Arpit Solanki

login the user is easy if you are using default user model from django.contrib.auth.models

from django.contrib.auth import authenticate, login
def user_login(request):
    # check here that request.method is POST or not.
    user = authenticate(username=request.POST.get('username'), password=request.POST.get('password'))
    if user is not None:
        login(request, user)
        # send some http response here that login successful or redirect to some other page

    else:
        # return an error page saying that username password not correct

authenticate function will check for username and password in User table in the database if it founds a user matching query then it returns the user object else it will return None. You might not want to manage sessions as django already sets a cookie for every user that successfully logs in so if user has logged in once then he will not be required to enter password again.

It will not set session?just return user's object?

it won't return username and password. session is set in request object and when you send any response from django after login it will set session in the browser
