Python - PyQT5 print output inside the QTextEdit - python-3.x

Question

I have a pyqt5 code to print the dictionary output inside the QTextEdit
#code:-
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(565, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.text_output = QtWidgets.QTextEdit(self.centralwidget)
self.text_output.setGeometry(QtCore.QRect(20, 10, 501, 251))
self.text_output.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAsNeeded)
self.text_output.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAsNeeded)
self.text_output.setObjectName("text_output")
self.btn_dict = QtWidgets.QPushButton(self.centralwidget)
self.btn_dict.setGeometry(QtCore.QRect(30, 280, 101, 21))
self.btn_dict.setObjectName("btn_dict")
self.btn_clear = QtWidgets.QPushButton(self.centralwidget)
self.btn_clear.setGeometry(QtCore.QRect(180, 280, 101, 21))
self.btn_clear.setObjectName("btn_clear")
self.btn_exit = QtWidgets.QPushButton(self.centralwidget)
self.btn_exit.setGeometry(QtCore.QRect(310, 280, 101, 21))
self.btn_exit.setObjectName("btn_exit")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 565, 21))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.btn_dict.setText(_translate("MainWindow", "PrintDictionary"))
self.btn_clear.setText(_translate("MainWindow", "Clear"))
self.btn_exit.setText(_translate("MainWindow", "Exit"))
def dictionary(self):
new_dict = {
'Name' : 'Ron',
'Age' : '21',
'city' : 'NY'
}
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
So instead of printing output on console , i want to the output inside QTextEdit when clicked on PrintDictionary button as well as how to clear QTextEdit when clicked on clear button or exit application when clicked on exit button
I'm new to PYQT5 so please help me out.
Thanks

First of all, the dictionary function does not necessarily have to be a member of the class, and since you do not pass the self to it, I assume that you have badly indentured your code in that part.
Going to the point, you must use the clicked signal and call a lambda function that performs the action through the append and clear method of QTextEdit.
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
[...]
def dictionary(self):
new_dict = {
'Name' : 'Ron',
'Age' : '21',
'city' : 'NY'
}
return new_dict
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
ui.btn_dict.clicked.connect(lambda: ui.text_output.append(str(ui.dictionary())))
ui.btn_clear.clicked.connect(ui.text_output.clear)
MainWindow.show()
sys.exit(app.exec_())
