Can you communicate what the issue is, if there is one? Or are you simply asking for a code review? codereview.stackexchange.com Perhaps you can update your question to include a Minimal, Complete, and Reproducible code example and a more formal question. Based on the title it seems you want to do form validation, so including the form's code is a good place to start. — Drew Reese 13 secs ago

@GhostCat Don't use the existence of Code Review as a reason to close a question. From now on evaluate the question and use a reason like; needs focus, primarily opinion-based, etc. In the future please link to the help center and use wording that shows the post may be off-topic when recommending Code Review.

@Mast IMHO MRC. Normally I'd say "there is enough to provide a review" but here I don't think "a review" will cut it. Inline with why MRC is even a thing, I believe it should be closed to help the OP let us help, and to prevent the kerfuffle I can foresee.

I dont have much experience with threading and I'm not sure if there is a common way to do this. What I did in my only code with threading was target=callback and at the end of that callback I had set a IntVar() and I was working with wait_variable() in my other 2 functions. So I didnt needed the after method. Dont know if it helps, but since they closed your Question on Code Review I do not know if there will be another help here. — Atlas435 20 secs ago
