Please show us your attempt here. If you have not done a real try by yourself first, please do this and then come back.

But i will give you some hints:

- take some numbers as input. use input() function, give all numbers in one line, separated by comma or space
- split this input according the separator used at the input
- all input will be returned as string from input funtion. as you want to calculate with the numbers, you have to convert them from str to int
- using split creates a list with all input numbers as integers
- use a variable that will hold the current value of calculation
- to calculate, you need to use a for loop iterating over ste list of numbers, that gives you one item per iteration
- use the items from the for loop and calculate it with the variable
- if iteration of for loop is finished, you will have the requested result.
