+# and the other is a number, 
+# and returns the list obtained by shifting the elements in the list n places to the right (left) 
+# when n is positive (negative). 
+# Use wrap-around: if an element is shifted beyond the end of the list, 
+# then continue to shift starting at the beginning of the list.

+# ```
+# Example
+# Inputs>>> [1, 2, 3, 4, 5], 2

+# Inputs>>> [1, 2, 3, 4, 5], -2
