return programming

return
if n>=0: 
  

Here is what the above code is Doing:
1. It’s checking if the number is positive or negative.
2. If the number is positive, it’s adding up all the numbers from 1 to n.
3. If the number is negative, it’s subtracting all the numbers from n to 1.
4. Finally, it’s returning the sum.

You can test the function by calling it like this:

print(sum_numbers(10))
# Should return 55
print(sum_numbers(-10))
# Should return -55
