How to make auto space in lineEdit?

Question

Python

Hello!
I have a program in which, when entering data, an auto space is needed after every 4 characters.
And you also need a "\" character after 2 entered numbers.
Help!

There are two options, for a simple case, you can take InputMask.
For complex cases, use textChanged, when the user changes the text, you take the text from lineEdit on this event, parse it and substitute all the necessary characters, then replace the old text with a new line.
