Syntax : button.text()
Argument : It takes no argument.
Return : It returns string.

代码 ：

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
 
 
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
 
        # setting title
        self.setWindowTitle("Python ")
 
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for widgets
    def UiComponents(self):
 
        # creating a push button
        button = QPushButton("CLICK", self)
 
        # setting geometry of button
        button.setGeometry(200, 150, 100, 40)
 
        # adding action to a button
        button.clicked.connect(self.clickme)
 
        # getting text in button
        text = button.text()
 
        # creating label to print text
        label = QLabel(text, self)
        label.move(200, 200)
 
    # action method
    def clickme(self):
 
        # printing pressed
        print("pressed")
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
