PyQt5按钮点击信号clicked报错

Question

我把python文件包移动到了e盘，然后编辑器connect就报黄色了。
重装了python pyqt5 编辑器，现在编辑器没有黄色，但是：本机QT信号不可调用。
用之前写的代码运行不报错，现在写的就报错

代码：

import sys
from PyQt5.QtWidgets import QWidget, QApplication, QPushButton

class A(QWidget):
    def __init__(self):
        super(Ab, self).__init__()
        self.w()
    def w(self):
        self.resize(600, 600)
        self.b = QPushButton(self)
        self.b.clicked(self.xin)
    def xin(self):
        print("成功")
def main():
    app = QApplication(sys.argv)
    a = A()
    a.show()
    sys.exit(app.exec())
if __name__ == '__main__':
    main()

报错：

  Traceback (most recent call last):
  File "E:\python文件2\信号.py", line 22, in <module>
    main()
  File "E:\python文件2\信号.py", line 18, in main
    a = A()
        ^^^
  File "E:\python文件2\信号.py", line 9, in __init__
    self.w()
  File "E:\python文件2\信号.py", line 13, in w
    self.b.clicked(self.xin)
TypeError: native Qt signal is not callable

Answer 1

信号槽写的不对

self.b.clicked.connect(self.xin)
