How to change color of LineEdit when entering text?

Question

PyQt

There is a certain form with a bunch of LineEdit (QT Designer). I'm writing a small python script that would pass text from lineadity.
I would like to make sure that all LineEdits are filled with color by default, or have a color stroke. And when text is entered in LineEdit, it would become plain white without any fills.
Like in the pictures below:
