使用预先存在的字典向int值添加

Question

我试图建立一个函数，计算两部电影的相似性得分。已有的词典以电影为关键词，导演、体裁或主要演员都是价值观。有三个演员字典（列出每部电影的3个主演）。代码基本上运行良好，但有时我得到的结果比我应该得到的分数还要高。在

# create a two-variable function to deterime the FavActor Similarity score: 
def FavActorFunction(film1,film2):

    #set the result of the FavActor formula between two films to a default of 0.
    FavActorScore = 0
    #add 3 to the similarity score if the films have the same director.
    if direct[film1] == direct[film2]:
        FavActorScore += 3
    #add 2 to the similarity score if the films are in the same genre.
    if genre[film1] == genre[film2]:
        FavActorScore += 2
    #add 5 to the similarity score for each actor they have in common.
    if actor1[film1] == actor1[film2] or actor2[film2] or actor3[film2]:
        FavActorScore += 5
    if actor2[film1] == actor1[film2] or actor2[film2] or actor3[film2]:
        FavActorScore += 5     
    if actor3[film1] == actor1[film2] or actor2[film2] or actor3[film2]:
        FavActorScore += 5
    #print the resulting score.                    
    return FavActorScore

我的假设是，在计算演员的共同点时，有些事情是两次计算的。有没有办法修改代码的这一部分，以便得出更准确的结果？在

尝试使用in条件：

if actor1[film1] in (actor1[film2], actor2[film2], actor3[film2]):
   FavActorScore += 5 
if actor2[film1] in ( actor1[film2], actor2[film2], actor3[film2]):
   FavActorScore += 5
if actor3[film1] in (actor1[film2], actor2[film2], actor3[film2]):
   FavActorScore += 5

当你写a==b or c or d时，如果a等于b，或者如果c为真，或者如果d为真，则如果a等于b或c或d，则为true
