python中turtle的goto是什么_python turtle goto不工作了

我写了一个海龟程序，用数据在图表上画一条线。除了我调用chartlines中的make_line()之外，一切正常。goto太过分了，但没有划出一条线。即使我把乌龟。下来()在我进入While循环之前它没有画线。在import turtle

def Change_tekenpunt(x,y):

turtle.up()

turtle.goto(x,y)

turtle.down()

def xAxisTurtle(days):

xAxis = turtle

xAxis.ht()

Change_tekenpunt(-300, -220)

x = -275

for i in range(0,days+1):

xAxis.write(i)

Change_tekenpunt(x, -220)

x+=25

def yAxisTurtle():

yAxis = turtle

yAxis.ht()

Change_tekenpunt(-310, -200)

y = -160

for i in range(0, 1601, 200):

yAxis.write(i)

Change_tekenpunt(-330, y)

y+=50

def point():

turtle.begin_fill() # Begin to fill color in a shape

turtle.color("black")

turtle.circle(3) # Draw a circle

turtle.end_fill() # Fill
