快速批量修改檔名[機器學習]

import os

path = r'A:\Learning_OpenCV_3_Computer_Vision_with_Python_Second_Edition_Code\face_train'

filenames = os.listdir(path)
i = 1
for filename in filenames:
    print(filename)
    if os.path.isfile(os.path.join(path, filename)) == True:
        new_name = filename.replace(filename, 'neg-%d.pgm' % i)
        os.rename(os.path.join(path, filename), os.path.join(path, new_name))
        i += 1
print('修改完畢......')

1. path路徑要提前建立好
2. os.rename是完成修改的關鍵函式
