Hi Satish! Thanks for reaching out. Your code is correct. I am referring to both

Numbers =[1, 5, 64, 24, 5]
sum(Numbers)

and

list_1=[1,2,3,4]
sum(list_1)

(for the latter, please not that 'list' is a keyword in Python, so it is not good to use it as a variable name as well. Adding a number, particularly for the purpose of this course, solves the problem quite well!). What you need to do to solve the issue is execute the lines where you assign a value to the variable in question. I.e. in your case, please execute Numbers =[1, 5, 64, 24, 5] first and only then execute sum(Numbers). Otherwise what you have is code, but please remember that without executing it, it stays like that - just code. We must always execute it for it to have an effect on our work. Hope this helps.
Best,
Martin
