What would be the result of the following code? ages = {'aaron' : 6, 'kelly' : 3, 'abigail' : 1 } value = ages['brianna']

This code will no get executed properly.It will give keyerror Brianna.

Explanation:

In this dictionary we defined in the code the there is no key Brianna hence there is no corresponding value to Brianna.So assigning ages['Brianna] to value will obviously give error since there exits no key with this name.So the code will give error.
