python 随机打印路径中的jpg图片失败

Question

本人想用os模块实现随机引用路径中的jpg文件失败，求大神帮忙纠错

import win32print
import win32ui
from PIL import Image, ImageWin
from random import shuffle
import os

printer_name = win32print.GetDefaultPrinter()

for i in range(1):
    pth = r"C:/Users/77594/Desktop/test"
    files = [os.path.join(pth, fle) for fle in os.listdir(pth) if fle.endswith(".jpg")]
    shuffle(files)
    hDC = win32ui.CreateDC()
    hDC.CreatePrinterDC(printer_name)


    bmp = Image.open(files)

    scale = 1
    w,h = bmp.size
    hDC.StartDoc(files)
    hDC.StartPage()

    dib = ImageWin.Dib(bmp)

    dib.draw(hDC.GetHandleOutput(),(10,20,320,480))

    hDC.EndPage()
    hDC.EndDoc()
hDC.DeleteDC()

或者是用 f = random.choice(files) 

import win32print
import win32ui
from PIL import Image, ImageWin
import random
import os
printer_name = win32print.GetDefaultPrinter()
for i in range(1):
    pth = r"C:/Users/77594/Desktop/test"
    files = [os.path.join(pth, fle) for fle in os.listdir(pth) if fle.endswith(".jpg")]
    f = random.choice(files)
    hDC = win32ui.CreateDC()
    hDC.CreatePrinterDC(printer_name)
    bmp = Image.open(f)
    scale = 1
    w,h = bmp.size
    hDC.StartDoc(f)
    hDC.StartPage()
    dib = ImageWin.Dib(bmp)
    dib.draw(hDC.GetHandleOutput(),(10,20,320,480))
    hDC.EndPage()
    hDC.EndDoc()
hDC.DeleteDC()
