RecursionError: maximum recursion depth exceeded in comparison Fatal Python error: Cannot recover from stack overflow

I wanna to do a chat application when the user typing a URL or mail text will become hyperlink google.com / abc123@gmail.com similar like Whatsapp and Facebook Messenger. But now my code can't type anything will get the error:

RecursionError: maximum recursion depth exceeded in comparison Fatal Python error: Cannot recover from stack overflow.

I have no idea how to fix this problem. I research Google doesn't get any help for me.

    from PyQt5 import QtCore, QtGui, QtWidgets
    import re
    class Ui_Form(object):
        def setupUi(self, Form):
            Form.setObjectName("Form")
            Form.resize(400, 300)
            self.textBrowser = QtWidgets.QTextBrowser(Form)
            self.textBrowser.setGeometry(QtCore.QRect(20, 10, 361, 192))
            self.textBrowser.setObjectName("textBrowser")
            self.pushButton = QtWidgets.QPushButton(Form)
            self.pushButton.setGeometry(QtCore.QRect(300, 220, 93, 28))
            self.pushButton.setObjectName("pushButton")
            self.textEdit = QtWidgets.QTextEdit(Form)
            self.textEdit.setGeometry(QtCore.QRect(20, 210, 271, 41))
            self.textEdit.setObjectName("textEdit")

            self.retranslateUi(Form)
            QtCore.QMetaObject.connectSlotsByName(Form)
            self.pushButton.clicked.connect(self.getvalue)


        def retranslateUi(self, Form):
            _translate = QtCore.QCoreApplication.translate
            Form.setWindowTitle(_translate("Form", "Form"))
            self.pushButton.setText(_translate("Form", "PushButton"))

        def getvalue(self,email):
             s = self.textEdit.toPlainText()
             p = re.match("^.+@(\[?)[a-zA-Z0-9-.]+.([a-zA-Z]{2,3}|[0-9]{1,3})(]?)$",str (email))
             q = re.compile("^(http:\/\/www\.|https:\/\/www\.|http:\/\/|https:\/\/)?[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?$",re.IGNORECASE)
             if (p != None and self.getvalue(s) == True):
                 links ='{1}'.format(('mailto:'+s), s)
                 self.textBrowser.setOpenExternalLinks(True)
                 self.textBrowser.setText(links)
                 print("s")
             elif (q != None and self.getvalue(s) == True):
                 link ='{1}'.format(('http://'+s), s)
                 self.textBrowser.setOpenExternalLinks(True)
                 self.textBrowser.setText(link)
                 print("t")
             else:
                 self.textBrowser.append(s)
                 print("u")

    if __name__ == "__main__":
        import sys
        app = QtWidgets.QApplication(sys.argv)
        MainWindow = QtWidgets.QMainWindow()
        ui = Ui_Form()
        ui.setupUi(MainWindow)
        MainWindow.show()
        sys.exit(app.exec_())
