【问题描述】：

当我运行此代码时，我收到错误.. FileNotFound。我需要一些帮助才能知道我做错了什么。（只是提高我的python技能

  def resizemultiple():

    extensions = ('.jpeg','.jpg','.png','.svg')
    x = filedialog.askdirectory()
    Newwidth = int(width.get())
    Newheight = int(height.get())
    for f in os.listdir(x):
        if f.endswith(extensions):
            #Opening the image
            res = Image.open(f)
            #Splitting the word content
            splitimage = f.split('\\')[-1]
            fn, fext = splitimage.split('.')
            #resizing the image
            #messagebox.askyesnocancel(title=x, message="Do you want yo Resize the images")
            Newimage = res.resize((int(Newwidth), int(Newheight)))
            #messagebox._show(title="Resized", message="The Image Is Resized to " + str(Newwidth) + ' x ' + str(Newheight)+ " Press Ok To save it")
            Newimage.save('()res'.format(fext))

   messagebox._show(title="Resized", message="The Images are saved")

这就是我得到的

Exception in Tkinter callback

FileNotFoundError: [Errno 2] No such file or directory: 'deo.jpg'

【问题讨论】：

该错误自行解释。运行目录中没有 deo.jpg 文件。尝试更改为res = Image.open(os.join(x,f)) 我猜这就是你的意思

【解决方案1】：

listdir 不返回包含整个路径的文件。（见https://www.tutorialspoint.com/python/os_listdir.htm）

您需要前面的整个路径。喜欢

pth = os.path.join(x, f)
Image.open(pth)
