使用預先存在的字典添加到int值

Question

我試圖設置一個函數來計算兩個電影的相似度的分數。現有的詞典以電影爲關鍵詞，導演，流派或主演員都是價值觀。有三部演員字典（每部電影的3名主角演員均被列出）。代碼大多工作正常，但有時我得到的結果比我應該得到的更大。

# 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 

我的假設是，在統計他們有共同點的演員時，它會計算一些東西兩次。有沒有辦法修改這部分代碼，以獲得更準確的結果？

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  

Answer 1

嘗試用in條件：

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 

當你寫a==b or c or d如果等於B，或者c爲真，或者如果是，如果d爲真不是真的等於這是真的b或c或d。
