Question

我有一些相当不寻常的文字，内容如下：

[1]  It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, co
[2]  Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover .
[3]  Limit of Liability and Disclaimer of Warranty: e authors have used their best e orts in preparing this book, and the information provided herein as is. e information provided is sold without warranty, either express or implied.
[4]  Neither the authors nor Cartwheel Web will be held liable for any damages to be caused either directly or indirectly by the contents of this book.
[5]  Trademarks: Rather than indicating every occurence of a trademarked name as such, this book uses the names only in an editorial fashion and to the bene t of the trademark owner with no intention of infringement of the trademark.

..即括号中的行号，后跟行。

通常情况下，我会这样做：

    fn = "fn.txt"
    with open (fn, "r") as myfile:
        data=myfile.read().strip()

..但是，在[1] [2] ..中存储值之前，我有行号data后跟两个我想要删除的空格。我想知道如何在python中做到这一点。

Answer 1

您只需要在第一次出现的空白时进行拆分，然后取出每行的其余部分。所以，使用你的＆＃39; fn＆＃39;文件：

In [69]: with open('fn') as infile:
    data = [line.strip().split(None,1)[1] for line in infile]
   ....:     

In [70]: data
Out[70]: 
["It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, co",
 "Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover .",

Answer 2

由于行号可能具有不同的长度，但可能也不包含您可以依赖的将“行号”与文本分开的“两个空格”模式，最简单的方法是将字符串分开图案：

number, spaces, line = line.partition('  ')

Answer 3

您只需要找到第一个出现的两个空格

>>> new_data = ""
>>> with open (p, "r") as myfile:
...    for i in myfile.readlines():
...        new_data += i[i.find("  ")+2:]

组合行（删除行号）从python中的文本文件中创建段落
