How To Create Analog Clock in Python

In this article, we are going to learn how to create an Analog Clock in Python.

Requirements:

1. Python
2. Python Turtle Module
3. Basic Knowlege of Python and Turtle

Creating Analog Clock in Python

First, we need to import the clock image from turtle graphics module:

import turtle
import time

wndw = turtle.Screen()
wndw.bgcolor("black")
wndw.setup(width=600, height=600)
wndw.title("Analogue Clock")
wndw.tracer(0)

Then we have to draw the clock and define the hour, minutes and seconds of the clock:

def draw_clock(hr, mn, sec, pen):

    # Draw clock face
    pen.up()
    pen.goto(0, 210)
    pen.setheading(180)
    pen.color("green")
    pen.pendown()
    pen.circle(210)

    # Draw hour hashes
    pen.up()
    pen.goto(0, 0)
    pen.setheading(90)

    for _ in range(12):
        pen.fd(190)
        pen.pendown()
        pen.fd(20)
        pen.penup()
        pen.goto(0, 0)
        pen.rt(30)

Drawing the hand of the clock and adding the degree is the third step :

# Draw the hands
  # Each tuple in list hands describes the color, the length
  # and the divisor for the angle
  hands = [("white", 80, 12), ("blue", 150, 60), ("red", 110, 60)]
  time_set = (hr, mn, sec)

  for hand in hands:
      time_part = time_set[hands.index(hand)]
      angle = (time_part/hand[2])*360
      pen.penup()
      pen.goto(0, 0)
      pen.color(hand[0])
      pen.setheading(90)
      pen.rt(angle)
      pen.pendown()
      pen.fd(hand[1])

After that, we have to add a while True statement. A while True means a loop forever

while True:
    hr = int(time.strftime("%I"))
    mn = int(time.strftime("%M"))
    sec = int(time.strftime("%S"))

    draw_clock(hr, mn, sec, pen)
    wndw.update()
    time.sleep(1)
    pen.clear()

wndw.mainloop()

Code :

import turtle
import time

wndw = turtle.Screen()
wndw.bgcolor("black")
wndw.setup(width=600, height=600)
wndw.title("Analogue Clock")
wndw.tracer(0)

# Create the drawing pen
pen = turtle.Turtle()
pen.hideturtle()
pen.speed(0)
pen.pensize(3)


def draw_clock(hr, mn, sec, pen):

    # Draw clock face
    pen.up()
    pen.goto(0, 210)
    pen.setheading(180)
    pen.color("green")
    pen.pendown()
    pen.circle(210)

    # Draw hour hashes
    pen.up()
    pen.goto(0, 0)
    pen.setheading(90)

    for _ in range(12):
        pen.fd(190)
        pen.pendown()
        pen.fd(20)
        pen.penup()
        pen.goto(0, 0)
        pen.rt(30)

    # Draw the hands
    # Each tuple in list hands describes the color, the length
    # and the divisor for the angle
    hands = [("white", 80, 12), ("blue", 150, 60), ("red", 110, 60)]
    time_set = (hr, mn, sec)

    for hand in hands:
        time_part = time_set[hands.index(hand)]
        angle = (time_part/hand[2])*360
        pen.penup()
        pen.goto(0, 0)
        pen.color(hand[0])
        pen.setheading(90)
        pen.rt(angle)
        pen.pendown()
        pen.fd(hand[1])


while True:
    hr = int(time.strftime("%I"))
    mn = int(time.strftime("%M"))
    sec = int(time.strftime("%S"))

    draw_clock(hr, mn, sec, pen)
    wndw.update()
    time.sleep(1)
    pen.clear()

wndw.mainloop()

   How do you call the function?? I do not understand what pen does? can you explain further?
