Help loading INT from a file.

[lovepeace]

hello, I'm new here, and new to python. so please be patient with me lol
I'm making an app to track my cycling miles. I need to be able to load saved "miles" from a file and set the int to a global variable to be used by the app, and the reverse when miles are added I need to save or update the save file.
easiest way would be great, I'm new and its just a simple app. iv researched several ways to do it, but its all confusing to me.
any help would be greatly appreciated. Thank you!
