Python如何将连字号与换行符合并?

上面的代码不起作用,我尝试了几种不同的方法
我希望遍历整个文本文件并删除所有表示换行符的连字符。例如:
with open(filename, encoding="utf8") as f:
file_str = f.read()
re.sub("\s*-\s*", "", file_str)
with open(filename, "w", encoding="utf8") as f:
f.write(file_str)
任何帮助都将不胜感激。您不需要使用正则表达式:
I want to say that Napp Granade
serves in the spirit of a town in our district
of Georgia called Andersonville.
但是你当然可以,而且它比较短:
filename = 'test.txt'
# I want to say that Napp Granade
# serves in the spirit of a town in our dis-
# trict of Georgia called Anderson-
# ville.
with open(filename, encoding="utf8") as f:
lines = [line.strip('\n') for line in f]
for num, line in enumerate(lines):
if line.endswith('-'):
# the end of the word is at the start of next line
end = lines[num+1].split()[0]
# we remove the - and append the end of the word
lines[num] = line[:-1] + end
# and remove the end of the word and possibly the
# following space from the next line
lines[num+1] = lines[num+1][len(end)+1:]
text = '\n'.join(lines)
with open(filename, "w", encoding="utf8") as f:
f.write(text)
# I want to say that Napp Granade
# serves in the spirit of a town in our district
# of Georgia called Andersonville.
我们查找一个-
,后跟\n
,并捕获以下单词,即拆分单词的结尾。我们用捕获的单词和换行符来替换所有这些
不要忘记使用原始字符串进行替换,以便正确解释
\1
。连字号是否始终位于行尾,或者换行符之前是否也有空格字符?
with open(filename, encoding="utf8") as f:
text = f.read()
text = re.sub(r'-\n(\w+ *)', r'\1\n', text)
with open(filename, "w", encoding="utf8") as f:
f.write(text)
