turtle.Turtle.circle¶

Turtle.circle(radius, extent=None, steps=None)¶

Draw a circle with given radius.

Arguments: radius – a number extent (optional) – a number steps (optional) – an integer

Draw a circle with given radius. The center is radius units left of the turtle; extent - an angle - determines which part of the circle is drawn. If extent is not given, draw the entire circle. If extent is not a full circle, one endpoint of the arc is the current pen position. Draw the arc in counterclockwise direction if radius is positive, otherwise in clockwise direction. Finally the direction of the turtle is changed by the amount of extent.

As the circle is approximated by an inscribed regular polygon, steps determines the number of steps to use. If not given, it will be calculated automatically. Maybe used to draw regular polygons.

call: circle(radius) # full circle –or: circle(radius, extent) # arc –or: circle(radius, extent, steps) –or: circle(radius, steps=6) # 6-sided polygon

Example (for a Turtle instance named turtle): >>> turtle.circle(50) >>> turtle.circle(120, 180) # semicircle
