Try it:

import sys
from PyQt5.QtWidgets import QApplication, QPushButton

app = QApplication([])

def clickButton(w):
    # Check what you clicked here.                        # <-----
    return print(w.text())

widget  = QPushButton('Button 1')
widget.clicked.connect(lambda : clickButton(widget))

widget2 = QPushButton('Button 2')
widget2.clicked.connect(lambda : clickButton(widget2))

widget.setGeometry(300, 150, 100, 100)
widget.show()

widget2.setGeometry(450, 150, 100, 100)
widget2.show()

sys.exit(app.exec_())
