if line edit is empty put in a string - birdieman - Mar-15-2017

I am trying to see if a line edit is empty, and if so, put the word Other in it. What I have so far crashes

        if len(self.ui.carlabel) == 0:
            self.ui.carlabel.setText(str('Other'))

by the way, "carlabel" is a line edit, not a label
thanks

Shall we guess on what GUI you use?

sorry, I am using PyQt5 -- but I think I just need to know if (1) is the IF statement the correct way to see if a line edit is empty? and (2) the syntax of putting the word Other into a line edit. For now, assume the self.ui part is correct. thanks for responding

Statement likely incorrect. You are taking the length of the widget, not of the text inside it. Try

if len(self.ui.carlabel.text()) == 0:
if len(self.ui.carlabel.getText()) == 0:

or whatever method gets you the text of the widget.

I would try

if not self.ui.carlabel.text():
   self.ui.carlabel.setText('Other')
