adding numbers in a list

[Nickd12]

what im looking to do is add 25 to elements in a list but add 25 plus the last number

example

list = [0,0,0,0]

i want the output to be

list = [0,25,50,75]

25 plus the last number plus the spot on the first list? What would be the answer if the first list were [5, 10]?

If I follow the example

>>> def add_num_to_list(lst, num): ... new_list = [lst[0]] ... for i in lst[1:]: ... new_list.append(i+num+new_list[-1]) ... return new_list ... >>> print(add_num_to_list([0,0,0,0], 25)) [0, 25, 50, 75] >>> print(add_num_to_list([5,10], 25)) [5, 40]

Where the last printout is an answer to the question asked by @bowlofred

But if I follow the text description:

>>> def add_num_to_list(lst, num): ... new_list = [] ... for i in lst: ... new_list.append(i+num+(new_list[-1] if new_list else 0)) ... return new_list ... >>> print(add_num_to_list([0,0,0,0], 25)) [25, 50, 75, 100] >>> print(add_num_to_list([5,10], 25)) [30, 65] >>>
