如何在Python中读取行和删除行？

我想编辑一个文本文档，每10-12行末尾都有页码（将PDF转换为文本，并在页面末尾有页码）。我想删除这些特定的页码整数，不是在文本中，因为可以有页码50，也可以是一行，其中可以有50作为整数。所以我只想删除页码为整数的行

文本文档示例：

1 





militant Muslims use scriptures such as the 
Genesis story describing the destruction of 
Sodom and Gomorrah as justification (from Allah) 
for the hatred they vent on all things  non-
Muslim and especially on gay men.

A Word from the Author 

Today, in the 21st Century the majority of Muslims 
hold middle 

3 


Into The Darkness

were dozing fitfully in the rear of the van, they

4 


down. It blocked the narrow road.  
Ali Azzizi was the other man accompanying 
the women. 
5 

我希望从1-5中删除这些页码，但如果这些相同的页码出现在行与行之间的任何位置，则不应删除

我的代码

filename = input('filname')
filedata = None

temp = 1

with open(filename, 'r', encoding="utf8") as file:
    filedata = file.read()
    filedata.join(line.strip() for line in file)
    rahul = '                                                                                                                                    '
    for line in file:
        if(line=='1'):
         filedata = filedata.replace(line, ' ')







with open(filename, 'w', encoding="utf8") as file:
  file.write(filedata)

如果python的使用不是强制性的，您可以使用

grep-v'^[0-9][\s]*'test.txt

cristian@nb:~/$ grep -v '^[0-9][\s]*' test.txt

你有密码吗？在这里提问之前，你至少应该试着自己解决你的问题。您可以尝试使用正则表达式，因为您要删除的数字似乎在新行之间（数字5除外…），到目前为止您尝试了什么？你遇到的问题在哪里。表明你已经付出了努力…将所有内容读入内存，编辑文本，将所有内容写入文件。或者逐行读lin并决定哪一行写入新文件。然后删除旧文件，并将新文件重命名为旧名称。SRY我忘记了请看我的编辑问题。我被这个问题弄糊涂了，因为它几乎是的复制+粘贴，除了另一个是Java。为什么你想用不同的语言做同样的事情？
