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}
