How to determine if inputted number is a letter or number? (LineEdit)

Question

Are there any workaround on how to determine a letter or number on a string? or Is there a way to just allow number input on LineEdit? I don't want to use SpinBox though, it's not that customizable unlike LineEdit (Dynamic Font, Styles, etc..)

Thanks

I am having issues with SpinBox aswell but you can customize the font and styles of the spinbox by using a Theme and editing the LineEdit class since the spinbox uses a LineEdit in the back end.

In String documentation there are functions like is_valid_float() or is_valid_integer()

Thank you so much. I don't know why I didn't notice this in the documentation. Thank you again, cheers.
