python - os.walk 在第一次找到后停止寻找子目录

Question

我需要在目录中首次出现 repository.config 文件，然后停止在子目录中查找。

这是我的目录树:

./WAS80/base/disk1/ad/repository.config./WAS80/base/disk1/md/repository.config./WAS80/base/disk2/ad/repository.config./WAS80/base/disk3/ad/repository.config./WAS80/base/disk4/ad/repository.config./WAS80/base/repository.config./WAS80/fixpack/fp5/repository.config./WAS80/fixpack_suplements/fp5/repository.config./WAS80/supplements/disk1/ad/repository.config./WAS80/supplements/disk1/md/repository.config./WAS80/supplements/disk2/ad/repository.config./WAS80/supplements/disk3/ad/repository.config./WAS80/supplements/disk4/ad/repository.config./WAS80/supplements/repository.config

I need the ones in bold and stop looking in the subdirectories.

I started tinkering with this code, but I couldn't figure it out.

pattern='repository.config'
path='/opt/was_binaries'

    def find_all(name, path):
            result = []
            for root, dirs, files in os.walk(path):
                    if name in files:
                            result.append(os.path.join(root, name))
                            continue

            return result

这应该做你想做的:

import os

res = []

for here, dirs, files in os.walk(startdir, topdown=True):
    if 'repository.config' in files:
        res.append(os.path.join(here, 'repository.config'))
        dirs[:] = []

print(res)

每当遇到'repository.config' 文件时，将dirs 设置为[] 以防止os.walk从进一步下降到该目录树。

注意:重要的是就地更改dirs(即dirs[:] = [])而不是重新绑定(bind)它(dirs = []).,
