需要源码可以直接联系拿

方案一: 直接套用脚本,需可以看懂一些脚本逻辑

在该代码中,我们使用了 multiprocessing.Process 类来创建多个进程。在主程序中,我们计算了每个进程需要拷贝的目标文件夹数量,并使用这个数量创建了一个包含多个进程的列表。然后,我们启动了所有进程,并等待它们全部执行完毕。在所有进程结束后,我们记录结束时间,并输出用时。

该程序与之前的代码是一样的,先计算每个进程需要拷贝的目标文件夹数量,然后创建多个进程,每个进程处理一部分目标文件夹的拷贝工作。最后,我们依次启动所有进程,等待它们全部执行完毕。在所有进程结束后,我们记录结束时间,并输出用时

import shutil
import os
import multiprocessing
import time

def copy_folder(source_folder, dest_folders):
    """
    将文件夹 source_folder 复制到多个目标文件夹 dest_folders。
    如果目标文件夹已经存在,则先清空目标文件夹,然后复制。
    """
    for dest_folder in dest_folders:
        try:
            if os.path.exists(dest_folder):
                shutil.rmtree(dest_folder)
            shutil.copytree(source_folder, dest_folder)
            print(f"成功将 {source_folder} 复制到 {dest_folder}")
        except Exception as e:
            print(f"复制 {source_folder} 到 {dest_folder} 时发生错误:e}")

if __name__ == "__main__":
    # 需要复制的原始文件夹
    source_folder = "source/folder"
    
    # 需要复制到的多个目标文件夹
    dest_folders = ["/path/folder_1", "/path/folder_2", "/path/folder_3"]
    
    # 计算每个进程需要拷贝的目标文件夹数量
    processes_num = len(dest_folders)
    folders_per_process = len(dest_folders) // processes_num
    
    # 创建进程列表
    processes = []
    for i in range(processes_num):
        start = i * folders_per_process
        end = start + folders_per_process
        if i == processes_num - 1:
            end = len(dest_folders)
        process = multiprocessing.Process(target=copy_folder, args=(source_folder, dest_folders[start:end]))
        processes.append(process)
    
    # 记录开始时间
    start_time = time.time()
    
    # 启动所有进程
    for process in processes:
        process.start()
    
    # 等待所有进程结束
    for process in processes:
        process.join()
    
    # 记录结束时间并输出用时
    end_time = time.time()
    print(f"复制用时: {end_time - start_time} 秒")

方案二:直接调用封装脚本(写用例,执行脚本即可)

脚本实现封装后,只需要在MultiProcessCopy.yaml文件中写用例即可,此后执行Multiprocess_Copy.py脚本即实现多线程拷贝文件夹下所有内容到指定目录

目录介绍:

拷问文件到PYTHON环境 python拷贝文件到指定目录_目标文件

MultiProcessCopy.yaml配置拷贝文件的源地址和目标地址

source_folder: 原始文件夹路径

dest_folders: 需存放目标文件夹,可多个同时填写

MultiProcess:
  source_folder: \\127.0.0.1\d$\exportdir
  dest_folders:
    - \\127.0.0.2\d$\path1
    - \\127.0.0.2\d$\path2
-

PublicConfig.py脚本: 配置读取信息,方便调用

from Public_Utils.util_yaml import YamlReader

class YamlPath:
    def __init__(self):
        current = os.path.abspath(__file__)
        self.base_dir = os.path.dirname(os.path.dirname(current))

    def get_multiprocess_file(self):
        _config_path = self.base_dir + os.sep + "Public_Config\Public_yaml"
        self._config_file = _config_path + os.sep + "MultiProcessCopy.yaml"
        return self._config_file

class ConfigYaml:
    def __init__(self):   #初始yaml读取配置文件
        self.multiprocess_config= YamlReader(YamlPath().get_multiprocess_file()).yaml_data()
