字符串集之间的区别不起作用

Question

首先，感谢您的帮助，我几天来一直试图解决此问题。

档案myStopWords.txt：

è
ad
più
a
b
c
17

我的代码：

stopWord = set(open("<...>/myStopwords.txt").read().split("\n"))
oldWords = set(["a","b","ad", "è", "più","17","horse"])

print( oldWords.difference(stopWord) )

结果：

{'horse', 'ad', 'più', 'è'}

为什么不从set减去"ad" ， "è" ， "più" ？

结果应为{horse} 。

Answer 1

谢谢。 如先前评论中所建议，这是解决方案：

1）将文本文件转换为UTF-8。

2）

fname = '<...>/myStopwords.txt'

with open(fname, encoding='utf-8') as f:
    content = f.readlines()

stopWord = [x.strip() for x in content] 


oldWords = set(["a","b","ad", "è", "più","17","horse"])
print( oldWords.difference(stopWord) )
