Copy multiple files in Python
提问by hidayat
How to copy all the files present in one directory to another directory using Python. I have the source path and the destination path as string.
如何使用 Python 将一个目录中的所有文件复制到另一个目录。我将源路径和目标路径作为字符串。

You can use os.listdir()to get the files in the source directory, os.path.isfile()to see if they are regular files (including symbolic links on *nix systems), and shutil.copyto do the copying.
您可以使用os.listdir()获取源目录中的文件，使用os.path.isfile()查看它们是否是常规文件（包括 *nix 系统上的符号链接），并使用shutil.copy进行复制。
The following code copies only the regular files from the source directory into the destination directory (I'm assuming you don't want any sub-directories copied).
以下代码仅将源目录中的常规文件复制到目标目录中（我假设您不希望复制任何子目录）。
import os
import shutil
src_files = os.listdir(src)
for file_name in src_files:
full_file_name = os.path.join(src, file_name)
if os.path.isfile(full_file_name):
shutil.copy(full_file_name, dest)

Look at shutil in the Python docs, specifically the copytreecommand.
查看Python 文档中的shutil，特别是copytree命令。

If you don't want to copy the whole tree (with subdirs etc), use or glob.glob("path/to/dir/*.*")to get a list of all the filenames, loop over the list and use shutil.copyto copy each file.
如果您不想复制整个树（包括子目录等），请使用 或glob.glob("path/to/dir/*.*")获取所有文件名的列表，循环遍历列表并用于shutil.copy复制每个文件。
for filename in glob.glob(os.path.join(source_dir, '*.*')):
shutil.copy(filename, dest_dir)

import os
import shutil
os.chdir('C:\') #Make sure you add your source and destination path below
dir_src = ("C:\foooo\")
dir_dst = ("C:\toooo\")
for filename in os.listdir(dir_src):
if filename.endswith('.txt'):
shutil.copy( dir_src + filename, dir_dst)
print(filename)

Here is another example of a recursive copy function that lets you copy the contents of the directory (including sub-directories) one file at a time, which I used to solve this problem.
这是递归复制功能的另一个示例，它可以让您一次一个文件复制目录（包括子目录）的内容，我用它来解决这个问题。
import os
import shutil
def recursive_copy(src, dest):
"""
Copy each file from src dir to dest dir, including sub-directories.
"""
for item in os.listdir(src):
file_path = os.path.join(src, item)
# if item is a file, copy it
if os.path.isfile(file_path):
shutil.copy(file_path, dest)
# else if item is a folder, recurse
elif os.path.isdir(file_path):
new_dest = os.path.join(dest, item)
os.mkdir(new_dest)
recursive_copy(file_path, new_dest)
EDIT:If you can, definitely just use shutil.copytree(src, dest). This requires that that destination folder does not already exist though. If you need to copy files into an existing folder, the above method works well!
编辑：如果可以，绝对只使用shutil.copytree(src, dest). 这要求目标文件夹尚不存在。如果您需要将文件复制到现有文件夹中，上述方法效果很好！
