Python

Question

我有一个 python 脚本可以打印主目录中的所有目录。我想要的是打印除旧目录（我包含在排除列表中）之外的所有目录。

为此，我使用以下脚本：

include = 'C://Data//'
exclude = ['C:/Data//00_Old']

for root, dirs, files in os.walk(include, topdown=False):
    dirs[:] = [d for d in dirs if d not in exclude]
    for name in dirs:
        directory = os.path.join(root, name)
        print(directory)

问题是：它正在打印所有目录，包括被排除的目录。我做错了什么？

Answer 1

文件系统相关需求最好使用pathlib模块。我建议尝试这样的事情。

from pathlib import Path

files = list(Path('C:/Data/').glob('**/*')) #recursively get all the file names
print([x for x in files if 'C:/Data/00_Old' not in str(x)])

Answer 2

要进一步简化它，您可以这样做：

from pathlib import Path

# I'm assuming this is where all your sub-folders are that you want to filter.
include = 'C://Data//' 
# You don't need the parent 'C://Data//' because you looping through the parent folder.
exclude = ['00_Old']

root_folder = Path(include)

for folder in root_folder.iterdir():
    if folder not in exclude:
        # do work

Python - 打印除一个目录外的所有目录

Python - Print all the directories except one

os.walk
