批量替换文件夹下的图片后缀名

废话不多说，直接上code

import os
 
 
path = 'F:/dataset'
 
#
#print(os.listdir(path))
for filename in os.listdir(path):
    print(filename)
# filename = r'\slice_0001_266_266_1.50_1.50.npy'
    transF = os.path.splitext(filename)
    if transF[1] == '.npy':
        new_file_name = transF[0] + '.png'
        os.chdir(path)
        os.rename(filename,new_file_name)
