复制文件

只限于当前路径的

import os
from multiprocessing import Pool, Manager


# copy 文件

    # 首先打开一个文件
    fread = open(olderFileName + "/" + file, "r", encoding='UTF-8')

    content = fread.read()
    fwrite.write(content)
    fread.close()
    fwrite.close()
    queue.put(file)
    pass


def main():
    olderFileName = input("请输入您的文件名字")

    newFileName = olderFileName + "-复制文件"

    os.mkdir(newFileName)  # 创建新文件

    olderFileNames = os.listdir(olderFileName)  # 列出文件夹中所有的数据

    # 在进程池中进行操作
    p = Pool(5)
    queue = Manager().Queue()
    for file in olderFileNames:
        p.apply_async(work_copy_file, (file, olderFileName, newFileName, queue))

    num = 0
    allNum = len(olderFileNames)

        queue.get()
        num += 1
        copyRate = num / allNum
        print("进度是", copyRate * 100, )
    print('完成了')
