Simple printing the text for a QLineEdit

[thewolf]

I'm simply trying to print whatever the user has typed in the QLineEdit named self.snTextBox using the QPushButton called self.cfButton. I tried using str for both but it makes no difference. What do I need to do here? The self.enButton works calling the function enterNewHardware.

App won't even run with the below.


I'm getting this error:

Error:
self.cfButton.clicked.connect(print(serialNumber))
TypeError: argument 1 has unexpected type 'NoneType'

class hardwareTab(QWidget):
    def __init__(self):
        super().__init__()
        self.snLabel = QLabel("SERIAL NUMBER")
        self.snTextBox = QLineEdit()
        self.modelLabel = QLabel("MODEL")
        self.modelTextBox = QLineEdit()
        self.userLabel = QLabel("USER")
        self.userTextBox = QLineEdit()
        self.enButton = QPushButton("ENTER NEW HARDWARE")
        self.cfButton = QPushButton("CLEAR FIELDS")
        self.seButton = QPushButton("SEARCH/EDIT HARDWARE")
        self.activeCheckbox = QCheckBox("ACTIVE")

        layout = QVBoxLayout(self)
        layout.addWidget(self.snLabel)
        layout.addWidget(self.snTextBox)
        layout.addWidget(self.modelLabel)
        layout.addWidget(self.modelTextBox)
        layout.addWidget(self.userLabel)
        layout.addWidget(self.userTextBox)
        layout.addWidget(self.activeCheckbox)
        layout.addWidget(self.enButton)
        layout.addWidget(self.cfButton)
        layout.addWidget(self.seButton)

        self.enButton.clicked.connect(enterNewHardware)

        serialNumber = self.snTextBox.text()
        self.cfButton.clicked.connect(print(serialNumber))
