Save User Input From LineEdit Box To Variable

[digitalmatic7]

I have an input box for user to type their username.

I want that user input saved as a variable.

Here's what I have so far:

self.inputUsername = QtWidgets.QLineEdit(self.centralwidget)
        self.inputUsername.setGeometry(QtCore.QRect(10, 30, 151, 20))
        self.inputUsername.setClearButtonEnabled(True)
        self.inputUsername.setObjectName("inputUsername")

I'm still not sure if TEXTCHANGED is the right function I want...

self.inputUsername.textChanged.connect(self.Username)

Then call it:

def Username(self):
        username = self.inputUsername.text()

I've tried 100 different ways to set the variable, replacing textchanged with textset, 30 different things on stackoverflow. Nothing works

The fact that this seems to basic and I've spend 8 hours on it is killing me

Edit:
I got this working by playing around in Qt Designer:

self.lineEdit.textChanged['QString'].connect(self.lineEdit_2.setText)

It sets the user entered text from 1 input box to another...

As far as saving from the input box to a string / variable, still no luck.
