How to delete multiple characters in a textbox using selenium?

Question

Python

Greetings.
The problem is this: using selenium, you need to remove several characters from the text field.
I used the following code: in chromdriver it worked correctly, but in geckodriver, instead of deleting it, it prints some kind of krakozyabry: Is it somehow done differently in mazilla?
inputTotalf.send_keys('\b\b\b')

Answer 1

inputTotalf.clear()
or

inputTotalf.click()
inputTotalf.clear()
