python利用shutil将将一路径下的图像复制到另一路径下

from os import listdir,path,mkdir
import shutil

filePath='..\data\origindata'
imageId=listdir(filePath)

def image_obtain():
    newPath = '..\data\image'
    if not path.isdir(newPath):
        mkdir(newPath)
    for id in imageId:
        imagePath=path.join(filePath,id,'images',id+'.png')
        if path.exists(imagePath) and not path.exists(path.join(newPath,id+'.png')):
            shutil.copy(imagePath,newPath)

if __name__=='__main__':
    image_obtain()
