python - 是否可以使用 python 复制包含和排除模式的文件？

Question

我需要从带有模式的目录中复制文件。因为我做了如下，

from fnmatch import fnmatch, filter
from os.path import isdir, join
from shutil import copytree, ignore_patterns

def include_patterns(*patterns):

    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


src_directory = r'SOURCH_PATH'
dst_directory = r'DST_PATH'
ignored_directory = r'DST_PATH2'
copytree(src_directory, ignored_directory,ignore=ignore_patterns('*.bat'))
copytree(src_directory, dst_directory,ignore=include_patterns('*.xls'))

如果目标目录已经存在，Copytree 将引发错误。所以我需要执行这样的复制

copytree(src_directory, ignored_directory,ignore=ignore_patterns('*.bat'), ignore=include_patterns('*.xls'))

或者是否有任何参数来执行包含模式和排除模式的复制操作？

如何做到这一点？

假设您想要覆盖目标文件夹（如果已经存在），您可以通过以下方式轻松解决您的问题：

if os.path.exists(destination_path):
    shutil.rmtree(destination_path)
shutil.copytree(<your_params>)
