Report issue
In this article we will see how we can get the translated version of the text. Translated version of text is based on the disambiguation string and value of n for strings containing plurals. If no appropriate translated string is available translated text will be a UTF-8 string i.e a Unicode codec and can represent all characters in a Unicode string like QString. However, invalid sequences are possible with UTF-8 and, if any such are found, they will be replaced with one or more “replacement characters”, or suppressed. In order to do this we use tr method with the spin box object.
Syntax :, d_text, n) Argument : It takes 3 arguments first one is the text and other two are not compulsory first is disambiguation string and other is the integer that refer to the plurals number Return : It returns string
Below is the implementation
# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
class Window(QMainWindow):
    def __init__(self):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
        # setting range to the spin box
        self.spin.setRange(0, 999999)
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
        # setting status tip to the spin box
        self.spin.setStatusTip("Small Value")
        # creating a label
        self.label = QLabel(self)
        # making label multi line
        # setting label geometry
        self.label.setGeometry(100, 200, 250, 60)
        # translating the text
        value =
        # setting text to the label
        self.label.setText("Translated text : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
