Variables in PYQT5?

Question

Python

For example, I have two functions

def test1(self):
     .......
     punk = "hello"
     ......
.......
def test2(self):
     button=QPushButton("Click")
     button.clicked.connect(self.test1)
     .....
     print(punk)
     ......

Now the question is how to remove the punk variable from this function so that it does not lose its value set in the test1 function?
ps Instead of dots, another code that does not matter to this question
