Get list of movies directed by director- IMDbPY

I use the below code to get the director name of a particular movie. How can I get a list of all movies directed by the director. In this case I chose Interstellar and the Director I get will be Christopher Nolan. So how can I list all the movies directed by him?

from imdb import IMDb
ia = IMDb()

movie = ia.get_movie('0816692')
print "Name of the movie: ", movie
for i in movie['director']:
    print "Director: ", i
    for k in ia.search_person(str(i))[:1]:
        print k.personID

You can use the method get_person with the director's id as argument and find the names of the movies he directed by accessing the person object with the key director movie:

from imdb import IMDb
ia = IMDb()

movie = ia.get_movie('0816692')
print "Name of the movie: ", movie
for i in movie['director']:
    print "Director: ", i
    for k in ia.search_person(str(i))[:1]:
        director = ia.get_person(k.personID)
        print "Movies directed by %s" % director
        print "-------------------------------"
        for movie_name in director['director movie']:
            print movie_name

Update

I played a little bit with the library and found an even simpler approach to your problem without the nested for loops:

from imdb import IMDb
ia = IMDb()

movie = ia.get_movie('0816692')
print "Name of the movie: ", movie
for i in movie['director']:
    print "Director: ", i
    director = ia.search_person(i["name"])[0]
    ia.update(director)
    print "Movies directed by %s:" % director
    for movie_name in director["director movie"]:
        print movie_name
