RE: please im new to django.Need help understanding small code of django poll app.Highlighted with ******************

You are creating a dictionary with the name "context".

A dictionary is initialized by surrounding key-value pairs in braces.  { }

The key and the value is separated by a colon. :

The pairs are separated from each other by a comma.  ,

Example:  dictionary = { key1: value1, key2: value2, key3: value3 }

 

 

Inside the context dictionary is one key of a string with the data 'latest_question_list'.

That key is assigned the value of latest_question_list, which is a name that points to the value returned by Question.objects.order_by('-pub_date')[:5].

 

template.render is a function that takes a context and a request.

request was an argument passed into the view function named index.

context is the dictionary with the value we assigned it above.

 

template.render returns a value that is passed to HttpResponse, which the view named index returns.

 

If you are new to programming, you may want to take a look at the Python tutorial:

https://docs.python.org/3.6/tutorial/

    latest_question_list = Question.objects.order_by('-pub_date')[:5]

    template = loader.get_template('polls/index.html')

  ************please Explain me this part specially ('latest_question_list'= latest_question_list) ******** context = {

        'latest_question_list': latest_question_list,

    }
