摆脱重复

Question

有人可以帮忙吗？ 我有这样一个文件：

file = """he is a good man
she is a beautiful woman
this is a clever student
he is a bad neighbour"""

我想在文件中标记形容词，所以我在列表中提取它们，我想用另一种格式替换原始文件，如括号之间。所以列表形容词看起来像这样

ad =  "good, bad, clever, beautiful,"

我试过这个

for line in file.splitlines():
    for a in ad.split(','):
        if a in line:
            newline = line.replace(s, '[' + s + ']')
            result = file.replace(line, newline)
            print result

这给了我这个重复的结果：

he is a [good] man
she is a beatiful woman
this is a clever student
he is a bad neighbor

he is a good man
she is a[ beatiful] woman
this is a clever student
he is a bad neighbor

he is a good man
she is a beatiful woman
this is a[ clever] student
he is a bad neighbor

he is a good man
she is a beatiful woman
this is a clever student
he is a[ bad] neighbor

虽然我期待这样的结果

he is a [good] man
she is a [beautiful] woman
this is a [clever] student
he is a [bad] neighbour

Answer 1

问题在于你的循环。你没有很好地分割你的形容词，如果你打算使用替换，则不需要分割线。所以，你的代码应该如下：

adj = [word.strip() for word in ad.split(",") if word != ""]
for a in adj:
  if a in file:
    file = file.replace(a, '[' + a + ']')
print file
