pyqt5 / qtdesigner textbox default label

Question

I am trying to create a GUI for my Python program. One of the tools that I need is a text input box.

Now, I want a text label for this box saying "Please insert texts". Is there a function to add a label that shows inside the input textbox as default and disappear when user click the box to type?

I don't mind to use qt designer or pyqt5 coding.

placeholderText : QString This property holds the line edit's placeholder text

import sys
from PyQt5.QtWidgets import QLineEdit, QVBoxLayout, QApplication, QWidget

class Test(QWidget):
    def __init__(self):
        super().__init__()

        self.lineEdit = QLineEdit(placeholderText="Please insert texts.")  # <---

        vbox = QVBoxLayout(self)
        vbox.addWidget(self.lineEdit)

if __name__ == '__main__':
    app  = QApplication(sys.argv)
    w = Test()
    w.show()
    sys.exit(app.exec_())
