Python 如何判断两个字符串列表的匹配百分比

发布于06月23日

I am a beginner at python. Here I had a problem with comparing two lists. My first problem is the list should not be compared exactly. But It should be compared about 70% matching with other list and return true if exist. contains() method doesn't help in this case. Here is my list:

TotalTags = ["citrus", "orange", "vitamin-C", "sweet", "yellow", "vitamin-A"] #etc
LikedTags = ["citrus", "orange", "vitamin-D"]

fuzzywuzzy library in Sahil Desai's answer looks really simple.

Here is an idea with basic functions.

TotalTags = ["citrus", "orange", "vitamin-C", "sweet", "yellow", "vitamin-A"] #etc
LikedTags = ["citrus", "orange", "vitamin-C", "sweet", "yellow"]

print(len(set(TotalTags).intersection(set(LikedTags))) / len(TotalTags))  # 0.8333333
print(sum([True for x in TotalTags if x in LikedTags]) / len(TotalTags))  # 0.8333333
