Week 2: Methods, strings and lists/17b. Count positive and negative elements

@@ -0,0 +1,81 @@
+The program has a preformatted list variable numbers, which points to an integer-type list.
+Your task is to count how many negative and how many positive elements there are in the list. 
+Print the result as shown in the example below:

+Example execution:
+Positives: 10
+Negatives: 6
