Since the QString method isEmpty() is gone in PyQt5, what would be the equivalent of:

Code:

if QLineEdit.text().isEmpty();

That will work in 4 and 5?

Is it as simple as:

Code:

if not unicode(QLineEdit.text()):

?

Or even

Code:

if not QLineEdit.text():

or

Code:

if not len(QLineEdit.text()):
