如何使用子文件夹名称重命名并高效地复制python中的文件

import os

source_folder = '源文件夹路径'
target_folder = '目标文件夹路径'

for filename in os.listdir(source_folder):
    source_file = os.path.join(source_folder, filename)
    if os.path.isfile(source_file):
        # 执行重命名和复制操作

subfolder_name = os.path.basename(os.path.dirname(source_file))
new_filename = subfolder_name + '_' + filename

target_file = os.path.join(target_folder, new_filename)

with open(source_file, 'rb') as src_file, open(target_file, 'wb') as dst_file:
    dst_file.write(src_file.read())

import os

source_folder = '源文件夹路径'
target_folder = '目标文件夹路径'

for filename in os.listdir(source_folder):
    source_file = os.path.join(source_folder, filename)
    if os.path.isfile(source_file):
        subfolder_name = os.path.basename(os.path.dirname(source_file))
        new_filename = subfolder_name + '_' + filename
        target_file = os.path.join(target_folder, new_filename)
        with open(source_file, 'rb') as src_file, open(target_file, 'wb') as dst_file:
            dst_file.write(src_file.read())
