You have a list of numbers represented in one single string:
"13,27,5,67,39,2,10,89,41,7,9,73"
Iterate over this numbers and increase each of them by 2 (result should looks like this: "15,29,7,...") Print the new numbers as one comma-separated string to the console (format like the origin list of numbers represented in one single string) Use loops and str.split()
numbers = "13,27,5,67,39,2,10,89,41,7,9,73"
# put your code here
print(new_numbers) # 15,29,7,69,41,4,12,91,43,9,11,75
