Heading 0.0 turtle. Circle ( radius, extent=None, steps=None ) Parameters:.

radius – a number. extent – a number (or None). steps – an integer (or None) 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. May be used to draw regular polygons.

Undo turtle. Speed ( speed=None ) Parameters: speed – an integer in the range 0.10 or a speedstring (see below) Set the turtle’s speed to an integer value in the range 0.10.

If no argument is given, return current speed. If input is a number greater than 10 or smaller than 0.5, speed is set to 0. Speedstrings are mapped to speedvalues as follows:. “fastest”: 0. “fast”: 10.

“normal”: 6. “slow”: 3. “slowest”: 1 Speeds from 1 to 10 enforce increasingly faster animation of line drawing and turtle turning.

Attention: speed = 0 means that no animation takes place. Forward/back makes turtle jump and likewise left/right make the turtle turn instantly. Drawing state turtle. Pendown ( ) turtle.

If resizemode is set to “auto” and turtleshape is a polygon, that polygon is drawn with the same line thickness. If no argument is given, the current pensize is returned.

Pencolor(colorstring) Set pencolor to colorstring, which is a Tk color specification string, such as 'red', 'yellow', or '#33cc8c'. Pencolor((r, g, b)) Set pencolor to the RGB color represented by the tuple of r, g, and b. Each of r, g, and b must be in the range 0.colormode, where colormode is either 1.0 or 255 (see ). Pencolor(r, g, b). colormode 1.0 turtle.

Pencolor ( '#32c18f' ) turtle. Pencolor (50.0, 193.0, 143.0) turtle. Fillcolor (.args ) Return or set the fillcolor. Four input formats are allowed: fillcolor Return the current fillcolor as color specification string, possibly in tuple format (see example). May be used as input to another color/pencolor/fillcolor call. Fillcolor(colorstring) Set fillcolor to colorstring, which is a Tk color specification string, such as 'red', 'yellow', or '#33cc8c'.

Fillcolor((r, g, b)) Set fillcolor to the RGB color represented by the tuple of r, g, and b. Each of r, g, and b must be in the range 0.colormode, where colormode is either 1.0 or 255 (see ). Fillcolor(r, g, b). Fillcolor ( 'violet' ) turtle. Fillcolor 'violet' turtle. Pencolor (50.0, 193.0, 143.0) turtle.

Fillcolor (( 50, 193, 143 )) # Integers, not floats turtle. Fillcolor (50.0, 193.0, 143.0) turtle. Fillcolor ( '#ffffff' ) turtle. Fillcolor (255.0, 255.0, 255.0) turtle. Color (.args ) Return or set pencolor and fillcolor. Several input formats are allowed.

They use 0 to 3 arguments as follows: color Return the current pencolor and the current fillcolor as a pair of color specification strings or tuples as returned. Color(colorstring), color((r,g,b)), color(r,g,b) Inputs as in, set both, fillcolor and pencolor, to the given value. Color(colorstring1, colorstring2), color((r1,g1,b1), (r2,g2,b2)).

Goto ( 0, - 22 ) turtle. Left ( 100 ) turtle. Position (0.00,-22.00) turtle. Heading 100.0 turtle.

Write ( arg, move=False, align='left', font=('Arial', 8, 'normal') ) Parameters:. arg – object to be written to the TurtleScreen. move – True/False. align – one of the strings “left”, “center” or right”. font – a triple (fontname, fontsize, fonttype) Write text - the string representation of arg - at the current turtle position according to align (“left”, “center” or right”) and with the given font. If move is true, the pen is moved to the bottom-right corner of the text. By default, move is False.

If rmode is not given, return current resizemode. Different resizemodes have the following effects:.

“auto”: adapts the appearance of the turtle corresponding to the value of pensize. “user”: adapts the appearance of the turtle according to the values of stretchfactor and outlinewidth (outline), which are set. “noresize”: no adaption of the turtle’s appearance takes place.

Resizemode(“user”) is called by when used with arguments. Resizemode 'noresize' turtle. Resizemode ( 'auto' ) turtle.

Set resizemode to “user”.

If and only if resizemode is set to “user”, the turtle will be displayed stretched according to its stretchfactors: stretchwid is stretchfactor perpendicular to its orientation, stretchlen is stretchfactor in direction of its orientation, outline determines the width of the shapes’s outline.
