A data structure

[akulamartin]

Hi all how would you write a function called manipulate_data which acts as follows:

When given a list of integers, return a list, where the

first element is the count of positives numbers

and the

second element is the sum of negative numbers

.
NB: Treat 0 as positive.

What have you tried? Show us your best attempt and ask specific questions regarding possible problems/errors.

def manipulate_data(list):
 for num in range(list):
   if list.item()<0:
   
   if list.item()>0:

how would i write it?

as a module!

but i probably would code the function and caller in the same file to make testing go smoother since this is a very complicated data structure.

akulamartin, we're happy to help you learn Python but we're not going to do your homework for you. When you post here, you should ask your question, not copy-paste your homework prompt.

In this case, you need to provide your code (with any input hard-coded to reproduce the problem), your expected output, and your actual output, which may be an error message (which should be included in full), along with a natural language explanation of what you think it should work when it doesn't, or a question other than "why doesn't this work?" There are loads of resources if you're not quit there yet.

def manipulate_data(list):
 for num in range(list):
   if list.item()<0:
   
   if list.item()>0:

1) don't call your variable "list", that's a builtin function that you shouldn't overwrite.
2) why are you using range()?  for num in list works fine.
3) you'll get an error without a body in the if blocks.
