+Combines two lists into a dictionary, where the elements of the first one serve as the keys and the elements of the second one serve as the values.
+The values of the first list need to be unique and hashable.
+
+Use `zip()` in combination with a list comprehension to combine the values of the two lists, based on their positions.
+
+```py
+def to_dictionary(keys, values):
+  return {key:value for key, value in zip(keys, values)}
+```
+
+```py
+to_dictionary(['a', 'b'], [1, 2]) # { a: 1, b: 2 }
+```
