从特定行向后追加到新文件

Question

我想从url链接后面的某一行添加链接，该链接是一个.txt文件，包含类似于以下内容的内容：

X-Y-Z

3 -- 5-1

6 -- 4-2

7-2-3

等等..。我只设法让它读取所有的文件并将它们附加到一个新的文件中，但是我想省略第一行。

import urllib.request as ur
import shutil
with ur.urlopen(#link) as link, open("#filePath", 'ab') as Data:
        shutil.copyfileobj(link, Data)

有没有一种方法可以分割url中的行以附加到新文件中？

Answer 1

只需显式跳过第一行：

import urllib.request as ur
import shutil
with ur.urlopen(#link) as link, open("#filePath", 'ab') as Data:
    link.readline()  # Reads one line, discards it, leaves link positioned after it
                     # next(link, None) should also work; there are subtle differences,
                     # but either should work here
    shutil.copyfileobj(link, Data)
