PyQt5信号绑定问题

Question

from PyQt5.Qt import *  
from sys import argv  
  
app = QApplication(argv)  
  
main = QWidget(None)  
for i in range(10):  
    b = QPushButton(str(i), main)  
    b.clicked.connect(lambda: print(i))  
    b.move(i*100, 0)  
  
main.show()  
app.exec()

10个按钮，无论按哪一个都打印出9。请问这是为啥呢，我用pyqySignal绑定也是这样
