python文件夹操作，,1.遍历文件夹下所有

1.遍历文件夹下所有文件
2.将后缀为.DCM的文件复制到指定文件夹

import osimport shutildef all_path(dirname):    result = []#所有的文件    for maindir, subdir, file_name_list in os.walk(dirname):        # print("1:",maindir) #当前主目录        # print("2:",subdir) #当前主目录下的所有目录        # print("3:",file_name_list)  #当前主目录下的所有文件        if len(subdir) == 0 and len(file_name_list) < 5:            for filename in file_name_list:                apath = os.path.join(maindir, filename)#合并成一个完整路径                result.append(apath)        elif len(subdir) > 0:            for filename in file_name_list:                apath = os.path.join(maindir, filename)  # 合并成一个完整路径                result.append(apath)        else:            continue    return resultdef copy(all_list):    new_path = r‘/media/awifi/40FD960833674C19/workspace/示范区柯桥确诊/DR_FOR_TEST‘    for i in all_list:        if not i.endswith(‘.DCM‘):            continue        else:            print(i)            name = os.path.basename(i)            new_name = new_path + ‘/‘ + name            shutil.copyfile(i, new_name)if __name__ == ‘__main__‘:    result = all_path("/media/awifi/40FD960833674C19/workspace/示范区柯桥确诊/DR")    copy(result)
