三个按钮，button_1,button_2,button_3

想点击哪个显示哪个，为什么我这一直都是输出button 1

环境：Windows 10， python 3.7.9

from PyQt5 import QtWidgets

class Program(QtWidgets.QWidget):

    def __init__(self):
        super(Program, self).__init__()
        layout = QtWidgets.QVBoxLayout(self)
        for n in range(3):
            new_b = QtWidgets.QPushButton(self)
            new_b.setText('button {}'.format(n+1))
            new_b.clicked.connect(lambda n=n: print('button {}'.format(n+1)))
            layout.addWidget(new_b)

if __name__ == '__main__':
    import sys

    app = QtWidgets.QApplication(sys.argv)
    window = Program()
    window.show()
    sys.exit(app.exec_())
