我使用pdfminer将pdf转换为txt。问题是pdfminer在pdf行的末尾添加了\ n，但句子并未在此结束。您会在下面的文本中看到每一行都是句子，这是不对的。我还给出了其他版本的文本，以显示新行字符在哪里。例如
quan-
tum population.
应该用一句话。因此，我用\ n替换了\ n，此问题已解决。但是其他\ n都替换了我不想要的。
Balanced Quantum Classical Evolutionary Algorithm(BQCEA)
Muhammad Shahid, Hasan Mujtaba, Muhammad Asim, Omer Beg
Abstract
With advancement in Quantum computing, classical algorithms are adapted and integrated
with Quantum properties such as qubit representation and entanglement. Although these
properties perform better however pre-mature convergence is the main issue in Quantum
Evolutionary Algorithms(QEA) because QEA uses only the best individual to update quan-
tum population. In this paper, we introduced a new way to update the quantum population
of QEA to avoid premature convergence

我已经尝试过此代码。
lines =tokenize.sent_tokenize(txt_str)
for l in lines:
s = l.replace('\n', '')
print(s)
这导致此。

我不希望空行消失。希望您能理解。
您可以如下尝试-\n的特定用例：
re.sub(r"-\n","",l)
输出：
