我试图弄清楚如何将 CAD 图纸(“.dwg”、“.dxf)从带有子文件夹的源目录复制到目标目录并维护原始目录和子文件夹结构。
- 原始目录:H:\Tanzania...\Bagamoyo_Single_line.dwg
- 源目录:H:\CAD\Tanzania...\Bagamoyo_Single_line.dwg
我在以下帖子中从@martineau找到了以下答案:Python Factory Function
from fnmatch import fnmatch, filter
from os.path import isdir, join
from shutil import copytree
def include_patterns(*patterns):
"""Factory function that can be used with copytree() ignore parameter.
Arguments define a sequence of glob-style patterns
that are used to specify what files to NOT ignore.
Creates and returns a function that determines this for each directory
in the file hierarchy rooted at the source directory when used with
shutil.copytree().
"""
def _ignore_patterns(path, names):
keep = set(name for pattern in patterns
for name in filter(names, pattern))
ignore = set(name for name in names
if name not in keep and not isdir(join(path, name)))
return ignore
return _ignore_patterns
# sample usage
copytree(src_directory, dst_directory,
ignore=include_patterns('*.dwg', '*.dxf'))
更新时间:18:21。以下代码按预期工作,除了我想忽略不包含任何 include_patterns('. dwg', ' .dxf')的文件夹
