在pyqt5中使用另一个按钮激活按钮，我应该使用if语句吗？

from PyQt5.QtCore import *
from PyQt5.QtWidgets import *

if __name__ == '__main__':
    app = QApplication([])
    window = QWidget()
    window.setWindowTitle('Activate Button Example')
    window.resize(200, 100)

    activate_button = QPushButton('Activate')
    activate_button.clicked.connect(lambda: activated_button.click())

    activated_button = QPushButton('Activated')

    layout = QVBoxLayout()
    layout.addWidget(activate_button)
    layout.addWidget(activated_button)

    window.setLayout(layout)
    window.show()

    app.exec_()
