Python Turtle帮助文档梳理

Python Turtle帮助文档真的很多，几十屏拉不到头。其中很多部分是重复的。近期进行了梳理，我将其分为全局控制、画布设置、画笔设置、画笔操作、互动等五个部分。

说明： 1）Python Turtle查询办法 help(turtle) 2)查询某函数xx的方法 help(turtle.xx)，例如help(turtle.home)

一、全局控制

clear(self)

reset(self)

home(self)

undo(self)

write(self, arg, move=False, align='left',

font=('Arial', 8, 'normal'))

speed(self, speed=None)

bye()

setundobuffer(self, size)

degrees(self, fullcircle=360.0)

distance(self, x, y=None)

towards(self, x, y=None)

pos(self)

radians(self)

xcor(self)

ycor(self)

listen(self,

xdummy=None, ydummy=None)

tracer(self,

n=None, delay=None)

turtles(self)

update(self)

mainloop(self)

exitonclick()

resizemode(rmode=None)

done = mainloop()

二、画布设置

setup(width=0.5, height=0.75, startx=None,

starty=None)

screensize(canvwidth=None, canvheight=None,

bg=None)

window_height(self)

window_width(self)

bgpic(self, picname=None)

三、画笔设置

pensize(self, width=None)= width()

pencolor(*args)

turtlesize = shapesize(self,

stretch_wid=None, stretch_len=None, outline=None)

settiltangle(self, angle)

shape(self, name=None)

hideturtle(self)

showturtle(self)

shapetransform(self, t11=None, t12=None,

t21=None, t22=None)

shearfactor(self, shear=None)

tiltangle(angle)=

tilt (angle)= settiltangle(angle)

color(self, *args)

fillcolor(self, *args)

pen(self, pen=None, **pendict)

resizemode(self, rmode=None)

register_shape(self, name, shape=None)= addshape(name,

shape=None)

四、画笔操作相关函数

pendown(self)

penup(self)

right (angle)

left (angle)

forward(self, distance)

back(self, distance)

goto(self, x, y=None)

circle(self, radius, extent=None,

steps=None)

dot(self, size=None, *color)

begin_fill(self)

end_fill(self)

begin_poly(self)

end_poly(self)

get_poly(self)

get_shapepoly(self)

clone(self)

stamp(self)

clearstamp(self, stampid)

clearstamps(self, n=None)

heading(self)

setheading(self, to_angle)

setpos = goto(self, x, y=None)

setx(self, x)

sety(self, y)

get_shapepoly(self)

filling(self)

getpen = getturtle(self)

getscreen(self)

isdown(self)

isvisible(self)

五、互动相关函数

onclick(self, fun, btn=1, add=None)

ondrag(self, fun, btn=1, add=None)

onrelease(self, fun, btn=1, add=None)

onkey(self, fun, key)

onkeypress(self, fun, key=None)

onkeyrelease = onkey(self, fun, key)

ontimer(self, fun, t=0)

numinput(self, title, prompt, default=None,

minval=None, maxval=None)

textinput(self, title, prompt)
