In this article we will see how we can get the suffix of the QDoubleSpinBox. In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns or adjectives, and verb endings, which form the conjugation of verbs. An inflectional suffix is sometimes called a desinence or a grammatical suffix or ending. By default there is no suffix to the double spin box although we can add suffix to it with the help of setSuffix method.

In order to do this we will use suffix method with the double spin box object.
Syntax : dd_spin.suffix()
Argument : It takes no argument
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, 500, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating double spin box
        d_spin = QDoubleSpinBox(self)
        # setting geometry to the double spin box
        d_spin.setGeometry(100, 100, 150, 40)
        # setting suffix
        d_spin.setSuffix(" is the Value")
        # step type
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType
        # adaptive step type
        # creating a label
        label = QLabel("GeeksforGeeks", self)
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)
        # making label multi line
        # getting suffix
        value = d_spin.suffix()
        # setting text to the label
        label.setText("Suffix = " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
