Python script to build Analog Clock in PyQt5

In this tutorial let’s write Python script to Create Analog Clock in PyQt5.

PyQt5 is a cross-platform GUI toolkit that includes Python bindings for the Qt v5 framework. Because of the capabilities and simplicity provided by this library, it is possible to create an interactive desktop application with great ease. A GUI application is made up of two parts: the front-end and the back-end.

Code to Create Analog Clock in PyQt5

from PyQt5.QtCore import *
import sys

# creating a clock 
class Clock(QMainWindow):


	def __init__(self):
		super().__init__()


		timer = QTimer(self)

		# update the whole code
		timer.timeout.connect(self.update)

		# setting start time of timer i.e 1 second
		timer.start(1000)

		self.setWindowTitle('Clock')


		self.setGeometry(200, 200, 300, 300)

		# setting background color to the window
		self.setStyleSheet("background : black;")


		self.hPointer = QtGui.QPolygon([QPoint(6, 7),
										QPoint(-6, 7),
										QPoint(0, -50)])

		# creating minute hand
		self.mPointer = QPolygon([QPoint(6, 7),
								QPoint(-6, 7),
								QPoint(0, -70)])

		# creating second hand
		self.sPointer = QPolygon([QPoint(1, 1),
								QPoint(-1, 1),
								QPoint(0, -90)])
		self.bColor = Qt.green

		# color for second hand
		self.sColor = Qt.red

	# method for paint event
	def paintEvent(self, event):

		# getting minimum of width and height
		# so that clock remain square
		rec = min(self.width(), self.height())

		# getting current time
		tik = QTime.currentTime()

		# creating a painter object
		painter = QPainter(self)


		# method to draw the hands
		# argument : color rotation and which hand should be pointed
		def drawPointer(color, rotation, pointer):

			# setting brush
			painter.setBrush(QBrush(color))

			# saving painter
			painter.save()

			# rotating painter
			painter.rotate(rotation)

			# draw the polygon i.e hand
			painter.drawConvexPolygon(pointer)

			# restore the painter
			painter.restore()

		painter.setRenderHint(QPainter.Antialiasing)

		# translating the painter
		painter.translate(self.width() / 2, self.height() / 2)

		# scale the painter
		painter.scale(rec / 200, rec / 200)

		# set current pen as no pen
		painter.setPen(QtCore.Qt.NoPen)


		# draw each hand
		drawPointer(self.bColor, (30 * (tik.hour() + tik.minute() / 60)), self.hPointer)
		drawPointer(self.bColor, (6 * (tik.minute() + tik.second() / 60)), self.mPointer)
		drawPointer(self.sColor, (6 * tik.second()), self.sPointer)


		# drawing background
		painter.setPen(QPen(self.bColor))

		# for loop
		for i in range(0, 60):

			# drawing background lines
			if (i % 5) == 0:
				painter.drawLine(87, 0, 97, 0)

			# rotating the painter
			painter.rotate(6)

		# ending the painter
		painter.end()


app = QApplication(sys.argv)
	
# creating a clock object
win = Clock()
	
win.show()
	
exit(app.exec_())
