How can I control the outliner's length in Python turtle?-CodePudding

I am making an analog clock with python, using turtle module.

I could configue a window size and a circle, But i can't finish outliner of a circle.

I didn't give any integer to get the complete ouliner. But it doesn't surround a circle entire.

Please, tell me if there is a something missing.

window = turtle.Screen()
window.setup(1000, 800)
window.bgcolor("black")
window.title("Analog Clock")
window.tracer(0)

t = turtle.Turtle()

t.color("#FFD700")

t.penup()
t.speed(0)
t.pensize(25)
t.hideturtle()
t.goto(0, -290)
t.pendown()
t.fillcolor("white")
t.begin_fill()
t.circle(300, 360)
t.end_fill()

thank you

The problem is your use of tracer() without any call to update(). You can either remove the window.tracer(0) line, or add a window.update() line after your t.end_fill() line.

I usually recommend avoiding tracer() and update() until you have your code basically working, just to avoid bugs like this.

from turtle import Screen, Turtle

screen = Screen()
screen.setup(1000, 800)
screen.bgcolor('black')
screen.title("Analog Clock")
screen.tracer(0)

turtle = Turtle()
turtle.hideturtle()
turtle.speed('fastest')  # no-op if `tracer(0)`
turtle.color('#FFD700')
turtle.pensize(25)

turtle.penup()
turtle.sety(-290)
turtle.pendown()

turtle.fillcolor('white')

turtle.begin_fill()
turtle.circle(300)
turtle.end_fill()

screen.update()
screen.mainloop()

Here is the solution to your problem with your posted code working properly :)

window = turtle.Screen()
window.setup(1000, 800)
window.bgcolor("black")
window.title("Analog Clock")

t = turtle.Turtle()

t.color("#FFD700")

t.penup()
t.speed(0)
t.pensize(25)
t.hideturtle()
t.goto(0, -290)
t.pendown()
t.fillcolor("white")
t.begin_fill()
t.circle(300, 360)
t.end_fill()

window.update()
