I'm new to Python selenium and today I'm stuck with an element, I don't know why but I can't find the element and sendkeys. Can anyone please explain for me why i can't find it by id / xpath / css selector ? and Also how can we find it and sendkeys ? 

Here is a screenshot of the element:

PS: I've tried java\_execute\_script but it doesn't work, I still don't know how to use it well.
