python tarfile 中 tar --strip 的等效功能，用于随机命名的子文件夹

如果您有路径 a/b/c，那么您可以在第一个 / 处拆分它并获取最后一个元素以获取 b/c

path = path.split('/',1)[-1]

您甚至可以使用变量来获得与 --Strip

Strip = 1  # 2,3,etc.

path = path.split('/',Strip)[-1]

基于您链接中的代码，但我没有对其进行测试

def members(tar,Strip):
    for member in tar.getmembers():
        member.path = member.path.Strip('/',Strip)[-1]
        yield member

# --- main ---

Strip = 1

with tarfile.open("sample.tar") as tar:
    tar.extractall(members=members(tar,Strip))

我已经想通了。 tar.extractall 中的成员文件可以使用 pathlib 库剥离其提取路径，例如 @H_469_3@member.path = p.relative_to(*p.parts[:Strip]) 其中 p = Path(member.path) 和 Strip 是剥离的文件夹数。

结果如下：

import tarfile
from pathlib import Path

def get_tar_members_Stripped(tar,n_folders_Stripped = 1):
    members = []
    for member in tar.getmembers():
        p = Path(member.path)
        member.path = p.relative_to(*p.parts[:n_folders_Stripped])
        members.append(member)
    return members

# --- main ---

Strip = 1

with tarfile.open(tarfile_path,'r') as tar:
 tar.extractall(members=get_tar_members_Stripped(tar,Strip))
