How do you take the user data from QLineEdit after the key starts?

[zymir]

If I understand you correctly, one of the options is:

UPD: If you don't find a response in the forums, get in the documentation: https://doc.qt.io/qt-5/qlineedit.html It describes in detail every kind of view, the signals of this view and stuff. ♪

from PyQt5.Qt import *
import sys
class Window(QWidget):

def init(self, parent=None):

QWidget.init(self, parent)
    self.edit = QLineEdit(self)

    self.edit.returnPressed.connect(self.enter_checker)

def enter_checker(self):
        self.userText = self.edit.text()
        self.edit.clear()

if name == "main":

app = QApplication(sys.argv)

window = Window()

window.show()

sys.exit(app.exec_())
