New submission from Leon Mintz :
Could typing.Literal (or analogous) accept a regex pattern to match against?
For example, if I want a duration string,
duration: str # allowed syntax: 3s, 3m, 3h etc.
vs
duration: LiteralPattern['[0-9]+[smh]']

I am not an expert, but why not to use time.sleep(5)?
If you are using wxPython, you may also try wx.Timer, in which you could set

You may notice that, for matching the regex (0|(1(01*0)*1))*, the left

After reading the first `1', automata expects `1' or ``00 or ``010
