[Dictionary] map key and value

문제: Implement a function that receives a list of Tuples, where every Tuple takes the form: (< Actor>,< Movie>,<Year>). The function should return two Dictionaries in a Tuple. The first dictionary should map from Actor to Movies, the second dictionary should map from Year to Movies.

 

Example 

movie_maps( [("Keanu Reeves",Reeves","The Matrix", 1999 ),("Keanu Reeves", Bill Ted's Excellent Adventure", 1989)])

#({"Keanu Reeves":["The Matrix",Matrix","Bill Ted's Excellent Adventure"]}, { 1999 :["The Matrix"], 1989:["Bill Ted's Excellent Adventure"]})

 

def movie_maps(l):
	actor_dic = {}
    year_dic = {}
    
    for t in l:
    	a, m, y = t
        
        if a not in actor_dic:
        	actor_dic[a] =[]
        if y not in year_dic:
        	year_dic[y] = []
        
        actor_dic[a].append(m)
        year_dic[y].append(m)
    
    return actor_dic, year_dic
