Serialize and Deserialize

Hi bit of a noob here, but I am creating a digital etch-a-sketch with a 64x64 matrix on a raspberry pi 4. I am using python for the coding language. I was thinking I could use Serialize and Deserialize as a way to save and reload image that are drawn on the screen. I can’t seem to finad any examples of how to use serialize/deserialize. Am I totally on the wrong track here? Does anyone have some good examples of using these functions? Thanks in advance!

as you probably found out, there isn’t really help for programming or python here, sorry about that. I hope you found better resources for those bits.
