#参考链接：PIL示例

from PIL import Image,ImageFont,ImageDraw
import os
def Modify_Image(Image_Path,num=1):
    img=Image.open(Image_Path)
    mod_img=ImageDraw.Draw(img)

    mod_img.text((img.size[1]*3/4,0),str(num),fill=(255,0,0),font=myfont)
    save_path=os.path.dirname(Image_Path)+os.sep+"modify"+os.path.splitext(Image_Path)[1]
    img.save(save_path)
if __name__=="__main__":
    path=r"C:\Users\chauncey\Desktop\c.jpg"

            break
    return result
def save_redis(result):
    r=redis.Redis(host=‘192.168.174.128‘,port=7000,db=0)
    for uuid_code in result:
        r.lpush(‘uuid_code1‘,uuid_code)
if __name__==‘__main__‘:
    result=create_code(200,21)
    save_redis(result)
