//有1-22个文件夹，各文件夹下有Detect_0文件夹，此文件夹下有source与mask文件夹，目的是将需要获取图片的

文件夹下的图片复制到新的文件夹下并按顺序重命名

				?

									import shutil

									//删除之前文件夹并新建空文件夹

									shutil.rmtree(r'E:\\all_project\\picture')

									os.makedirs("E:\\all_project\\picture\\source\\")

									//确定需要获取图片的文件夹编号

									# arr=["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22"]
