Python Pillow .ico convert to .gif

I used python pillow library because i need to convert .ico to .gif

So i used Pillow 6.1.0 ver with Python 3.7.0 I do the following:

from PIL import Image

im = Image.open("a.ico")
im.show()

im.save("a.gif")

.ico file has transparent background

But im.show() loaded Image is black background So finally i got black background .gif file

I want to know how i get transparent .gif conversion files!

im.show() loaded Image is black background

It is because Image.show() converts the image to .bmp (bitmap) before displaying it. And Bitmap in PIL doesn't supports Alpha (variable Transparency/Opacity). Therefore, the alpha data in your .ico image gets lost when you try to display the image using Image.show().

Solution:- Don't view image containing alpha values using Image.show(), instead save the image and then view it (via some Image processing package like photoshop etc, or using your OS's builtin image viewer like Photos in Windows 10).

I want to know how i get transparent .gif conversion files!

.gif (graphical interchange format) does not support Alpha channel. So, it is not possible for you to convert .ico file into a .gif while retaining the transparent regions. Therefore, it is not advised to save an image having Alpha channel to a .gif, because it ends up having artifacts and would degrade the quality of the original image.

Solution:- I would suggest you to choose a format like .png or .jp2, which supports alpha channel. They support a large range of colors too (as opposed to a GIF, which supports only 256 discrete colors (8 bit palette)).
