Accessing dictionary in django template engine

lets say I have a dictionary called credit_facilities, where I map credit facility id to its verbal reprsentation.

credit_facilities = {1 : 'Yes',2:'No',3:'Not sure'}

I have model object where I retrieve values to be used as key for the dictionary. For instance lets say the model is named "customer" and it has attribute called "credit_facility". So, customer.credit_facility give either 1,2 or 3. I want to use this value as a key in dictionary. Meaning, is there an equivalent in django template language for the follwoing epression. 

credit_facilities[customer.credit_facility]

Use a choices argument for your credit_facility field and the (automagic) get_credit_facility_display() method to get the associated label:

class Customer(models.Model):
    CREDIT_FACILITY_CHOICES = (
      (1, "Yes"),
      (2, "No"),
      (3, "Not sure")
      )
    credit_facility = models.IntegerField(
       "credit facility", 
       choices = CREDIT_FACILITY_CHOICES
       )

then:

>>> c = Customer(1)
>>> c.get_credit_facility_display()
"Yes"
