如何在多個類別中搜索和替換python中的關鍵字？

Question

假設我有一個字符串，其內容爲：

''' 
Looking closely we find Pepsi and Coca-cola have been the two two biggest brands of soda in the world for the past four years. 
''' 

，我想表示詞映射到其類別爲：

classes={"NAME":["pepsi","coca-cola", "james","jill"...],"CATEGORY":["soda","food","automobile"....],"NUMBER":["one","two","three","four"....]} 

所以，在最後我想有原始字符串：

Looking closely we find NAME and NAME have been the two biggest brands of CATEGORY in the world for the past NUMBER years 

一個簡單的字典，如：

rep = {"NAME": "pepsi", "CATEGORY": "soda"....} 

我可以替換上述詞典中的詞，但如果每個鍵有多個詞，我該怎麼辦？

這是我到目前爲止有：

stringh=sentence.lower() 

for i,j in rep.items(): 
    stringh = stringh.replace(j, i) 

print stringh 

Answer 1

通過列表

stringh=sentence.lower() 

for i,j in rep.items(): 
    for k in j: 
     stringh = stringh.replace(k, i) 

print stringh 

迭代
