python实现批量修改图片尺寸和图片名称

图片尺寸修改：

import os
from PIL import Image

filename = os.listdir("D:\\Process\\old")
base_dir = "D:\\Process\\old\\"
new_dir = "D:\\Process\\new\\"
size_m = 64
size_n = 64

for img in filename:
    image = Image.open(base_dir + img)
    image_size = image.resize((size_m, size_n),Image.ANTIALIAS)
    image_size.save(new_dir+ img)

图片名称修改：

import os
files = os.listdir("D://new")
i=0
for file in files:
    original = "D://new" + os.sep+ files[i]
    new = "D://new" + os.sep + str(i+1) + ".png"
    os.rename(original,new)
    i+=1
