## Python: Tips of the Day

Maps the values of a list to a dictionary using a function, where the key-value pairs consist of the original value as the key and the result of the function as the value:

Example:

```def tips_map_dictionary(itr, fn):
ret = {}
for a in itr:
ret[a] = fn(a)
return ret
print(tips_map_dictionary([2,4,6], lambda a: a * a))
```

Output:

```{2: 4, 4: 16, 6: 36}
```
