python 批量重命名

记录下批量重命名的代码。
主要运用了os模块的listdir和rename函数。

import os # 导入os模块
from tqdm import tqdm  # tqdm进度条模块
train_path = 'input/train/'
mask_path = 'input/train_masks/'

train_ids = os.listdir(train_path)
mask_ids = os.listdir(mask_path)
print(train_ids)
print(mask_ids)
for i in tqdm(range(len(train_ids)),total=len(train_ids)):
    old_train_name = train_path + train_ids[i]  #旧文件名称（加地址）
    new_train_name = train_path +str(i+1) + '.jpg'  #新文件名称（加地址）

    old_mask_name = mask_path + mask_ids[i]  
    new_mask_name = mask_path + str(i + 1) + '.jpg'

    os.rename(old_train_name,new_train_name)   
    os.rename(old_mask_name, new_mask_name)

print('Done')
