删除文本文件中没有的行\n

Question

嗨，我有一个文档，我链接了here，它有换行符。但是这些换行符不是由'/n'创建的，因为当我使用strip()甚至line[:-2]时，似乎无法摆脱它们。我想知道如何删除一些换行符--主要是在页面上运行的行，如：

Wimer John, gauger & cooper, 232 N Broad, h
1511 Callowhill

如果有帮助的话，这是pytessaract OCR文本。你知道吗

谢谢你

Answer 1

在我看来，文件的每个“记录”都由两个换行符分隔，其中“换行符”表示DOS样式的行尾，也就是说，一个回车（'\r'）后跟一个换行符（'\n'）。因此，我们应该首先对'\r\n\r\n'上的字节流进行拆分，以获得每个记录一个元素。你知道吗

然后，我们可以用replace()替换记录中嵌入的不需要的换行符（必须是未配对的）。在我看来，某些一次性嵌入的换行符前面有一个破折号，因此可能需要用空字符串替换'-\r\n'，以重新连接连字符包装的文本片段，但在此之后，我们应该用单个空格替换任何剩余的未成对换行符。你知道吗

因此我们有：

import re;

file = open('1128.txt');
lines = re.split('\r\n\r\n',file.read());
lines = map(lambda x: x.replace('-\s*\r\n','').replace('\r\n',' '),lines);
for e in lines: print e;

Answer 2

使用str字符串的strip()方法。如果没有参数，它会去掉所有类型的前导和尾随空格。你知道吗

Answer 3

可能用\r\n拆分？你知道吗

>>> file = open("1128.txt")
>>> required_stuff = file.read().split('\r\n')
>>> print required_stuff[:10]
['VVIL', '', '1076', '', 'VVIN', '', ' ', '', 'WILSTACH WILLIAM P. & CO. (Wgflliam P.', "TVz'Zsz\xe2\x80\x98ac7z Q\xc2\xbb C/mrles Scott), saddlery hardware,"]
>>> file.close()
