+
+Maps the values of a list to a dictionary using a function, where the key-value pairs consist of the value as the key and the mapped value.
+
+Use a `for` loop to iterate over the list's values, assigning the values produced by `fn` to each key of the dictionary.
+
+```py
+def map_object(itr, fn):
+  ret = {}
+  for x in itr:
+    ret[x] = fn(x)
+  return ret
+```
+
+```py
+map_object([1,2,3], lambda x: x * x) # { 1: 1, 2: 4, 3: 9 }
+```
