在python中将JFIF文件转换为JPEG

Question

我有一个文件夹与JFIF照片，我需要将它们全部转换成JPEG格式，我认为问题来自我的if语句，因为文件夹中有其他照片不需要转换或for循环。谢谢

from PIL import Image
import os

root = r"(my computer path to the folder)"

count = 0
for dirs, subdir, files in os.walk(root):
    for file in files:
        lastChar = file[-1:]
        if(lastChar == 'f'):
            img = Image.open(file)
            #file ends in .jfif, remove 4 characters
            fileName = file[:-4]
            #add jpg and save
            img.save(fileName + "jpg")

我现在正在收到这个错误，FileNotFoundError: Errno 2没有这样的文件或目录：'IMG_4242_1615254307.jfif‘

from PIL import Image
import os

root = r"my computer path to the folder"
print(root)
count = 0
for dirs, subdir, files in os.walk(root):
    for file in files:
        lastChar = file[-4:]
        if(lastChar == 'jfif'):
            img = Image.open(root+'\\'+file)
            #file ends in .jfif, remove 4 characters
            fileName = file[:-4]
            print(fileName)
            #add jpg and save
            img.save(root+'\\'+fileName + "jpg")
