How to put a gif in a program

Question

I'm trying to put a gif into my program but it doesn't appear animated, i tried to put all the images to make it animated but it didn't work, i tried using also chatGPT but it can't help me.

Is there a way i can put the .gif file to create the animation or do i need to use other libraries like Moviepy?
