How to add two values of the same key if there are more than two values in that key itself?

Question

so i have a dictionary:

a={'price':[1,2,3],'code':['abc','abc','def']}

I need to add the first two values of the key 'price' and store it in a variable. How can i do that?

basically what i want to do is add 1 and 2 not 3 in the key 'price'.

Answer 1

The following should give what you want:

new_var=a['price'][0]+a['price'][0]


 or

new_var=sum(a['price'][:2])
