reccomending, according to the selected listbox value

[umerselmani]

the code is a bit long, hope you understand it, i have this small app, where i have to implement data from 2 files, and then showing some of the values(of data) in list box. on the other side i have combined the values in nested dictionary. Now i have to recommend movie according the the value i will select from list box. Maybe the code i have written is wrong in some parts, though in the last part, when i have to write the code of recommendation, i have no clue how i have to write the code, i so it will recommend me movie, for further explanation, i will be writing in comments part if needed.

the recommendation if it is user based it will recommend movies according to the ratings they gave, if it is movie based, it will recommend acorrding to the genre

Inside the function def getRecommendations(prefs, person, similarity = sim_pearson):
its expecting the passed in prefs to be an object that can be iterated

for other in prefs:

you are calling this method with b=getRecommendations(STproject.dictionary,STproject.selected,similarity=sim_distance)
it looks like you want to be calling the instance instead of the class
b=getRecommendations(self.dictionary,self.selected,similarity=sim_distance)
The method dictionary does not return a iterable of prefs and the method selected does not return a person.
