import os def run_cfturbo(filename_batch, current_path): filename_cfxpost_bat = (current_path + '\\' + 'launcher_CFturbo' + '.bat') # write bat file fp_cfxpost_bat = open(current_path + '\\' + 'CFturbo.txt').readlines() fp_new_cfxpost_bat = open(filename_cfxpost_bat, 'w') try: for eachline in fp_cfxpost_bat: fp_new_cfxpost_bat.write(eachline.replace('filename', filename_batch)) #.replace('filename.cse', filename_cfx_cse)) finally: fp_new_cfxpost_bat.close() os.system(filename_cfxpost_bat) if __name__ == "__main__": filename_batch = r'C:\Users\Windows\Desktop\NPSH\impeller.cft-batch' #filename_cfx_cse = r'C:\Users\Windows\Desktop\NPSH\POST.cse' current_path = os.getcwd() run_cfturbo(filename_batch, current_path)

这段代码的作用是运行CFturbo软件，并执行cft.batch文件生成stp文件。具体来说，它会：

1. 读取当前路径下的`CFturbo.txt`文件，该文件中保存了运行CFturbo软件的命令行参数。
2. 将`filename_batch`参数替换到`CFturbo.txt`文件中指定的位置，以指定要执行的cft.batch文件路径。
3. 创建一个新的批处理文件`launcher_CFturbo.bat`，并将`CFturbo.txt`文件中的内容复制到其中，以生成运行CFturbo软件的批处理命令。
4. 调用`os.system()`函数运行`launcher_CFturbo.bat`批处理文件，以启动CFturbo软件，并执行cft.batch文件生成stp文件。

需要注意的是，`filename_batch`参数应该是cft.batch文件的完整路径，而不是文件名。如果您想要修改生成的stp文件保存路径，可以在`CFturbo.txt`文件中添加相应的命令行参数。

好的，根据你的要求，将以上代码修改为将修改后的文件命名恢复原来的命名，可以按照以下方式修改：

import os 
from datetime import datetime 
import random 
import string 

def restore_original_names(folder_path): 
    """ 
    批量将文件名恢复为原来的名称，需要在修改文件名之前备份原来的名称 
    :param folder_path: 文件夹路径 
    """ 
    for filename in os.listdir(folder_path): 
        full_path = os.path.join(folder_path, filename) 
        if os.path.isfile(full_path): 
            # 获取备份的文件名 
            backup_filename = os.path.splitext(filename)[0] + ".bak" 
            backup_full_path = os.path.join(folder_path, backup_filename) 
            if os.path.exists(backup_full_path): 
                # 将备份的文件名恢复为原来的文件名 
                os.rename(backup_full_path, full_path) 

def batch_rename_files(folder_path, random_string_length=0): 
    """ 
    批量重命名文件，名字改为该文件的创建或修改日期，如果有重名的文件，可以添加一个随机字符串 
    :param folder_path: 文件夹路径 
    :param random_string_length: 随机字符串长度，默认为0 
    """ 
    # 先将文件名备份 
    for filename in os.listdir(folder_path): 
        full_path = os.path.join(folder_path, filename) 
        if os.path.isfile(full_path): 
            # 获取文件的后缀名 
            file_extension = os.path.splitext(filename)[1] 
            # 备份原来的文件名 
            backup_filename = os.path.splitext(filename)[0] + ".bak" 
            backup_full_path = os.path.join(folder_path, backup_filename) 
            os.rename(full_path, backup_full_path) 

    # 批量重命名文件 
    for filename in os.listdir(folder_path):

        if os.path.isfile(full_path): 
            # 获取文件的创建时间或修改时间 
            timestamp = os.path.getmtime(full_path) 
            # 格式化时间 
            date_time = datetime.fromtimestamp(timestamp) 
            new_name = date_time.strftime("%Y-%m-%d %H-%M-%S") 
            # 添加随机字符串 
            if random_string_length > 0: 
                random_string = ''.join(random.choices(string.ascii_lowercase + string.digits, k=random_string_length)) 
                new_name += '-' + random_string 
            # 拼接新的文件名 
            new_filename = new_name + file_extension 
            new_full_path = os.path.join(folder_path, new_filename) 
            # 重命名文件 
            os.rename(full_path, new_full_path) 

    # 将文件名恢复为原来的名称 
    restore_original_names(folder_path) 

if __name__ == '__main__': 
    folder_path = 'your_folder_path' 
    batch_rename_files(folder_path, random_string_length=5)

这个修改后的代码首先会备份原来的文件名，然后批量重命名所有的文件，并最后将所有文件的名字恢复为原来的名称。

优化使得每检索50张照片，输出一次已检索文件数：import os from PIL import Image from multiprocessing import Pool def is_black_image(file_path): with Image.open(file_path) as img: pixels = list(img.getdata()) if all(sum(pixel) == 0 for pixel in pixels): return True else: return False def delete_black_images(file_path): if is_black_image(file_path): os.remove(file_path) print('{} has del'.format(file_path)) def batch_delete_black_images(folder_path): file_list = [] for f in os.listdir(folder_path): file_path = os.path.join(folder_path, f) if os.path.isfile(file_path): file_list.append(file_path) with Pool() as p: p.map(delete_black_images, file_list) if __name__ == '__main__': batch_delete_black_images(r'F:\H18\Dfinal640.tif\8-2')

为了每检索50张照片输出一次已检索文件数，您可以在 `batch_delete_black_images` 函数中添加一个计数器来实现。具体地，您可以在函数中添加一个变量 `count`，每删除一张黑色图片时，将计数器加1，并且当计数器能够被50整除时，打印当前已经检索的文件数。下面是修改后的代码：

import os
from PIL import Image
from multiprocessing import Pool

def is_black_image(file_path):
    with Image.open(file_path) as img:
        pixels = list(img.getdata())
        if all(sum(pixel) == 0 for pixel in pixels):
            return True
        else:
            return False

def delete_black_images(file_path):
    if is_black_image(file_path):
        os.remove(file_path)
        print('{} has del'.format(file_path))
        return True
    return False

def batch_delete_black_images(folder_path):
    file_list = []
    count = 0
    for f in os.listdir(folder_path):
        file_path = os.path.join(folder_path, f)
        if os.path.isfile(file_path):
            file_list.append(file_path)
    with Pool() as p:
        results = p.map(delete_black_images, file_list)
        for result in results:
            if result:
                count += 1
                if count % 50 == 0:
                    print('已检索 {} 个文件'.format(count))

if __name__ == '__main__':
    batch_delete_black_images(r'F:\H18\Dfinal640.tif\8-2')

注意，为了避免多个进程同时打印计数器的值，我们在每50次删除操作后只打印计数器的值，而不是实时打印。
