如何在 python turtle 模块中使画布更大

Question

我用python做了一个乌龟画程序，但是我画乌龟的画布不够大。我正在尝试使此画布更大，以便我可以在页面上放置更多内容并使内容更大。我正在 trinket.io 中对此进行编程。

Answer 1

我正在 trinket.io 中对此进行编程。

那是你的问题——不幸的是，这在 trinket.io 中是不可能的。

Trinket.io 不支持所有 turtle 方法。你可以阅读哪些是支持的here；我认为其余的不受支持。

这将适用于您的本地 python 解释器：

import turtle

print(turtle.Screen().screensize()) # returns (400,300) for me

但这会在 Trinket.io 中失败，并显示如下消息：

> AttributeError: 'Screen' object has no attribute 'screensize' on line 3 in main.py

文档暗示支持 turtle.setup()，但似乎不支持，因为这将在您的本地 python 解释器上运行，并且在 trinket.io 中失败。

import turtle

turtle.setup(500,500)

我在 trinket.io 中唯一能做的就是能够通过以下方式返回（未设置）尺寸：

print(turtle.window_height())
print(turtle.window_width())

Answer 2

看起来你可以使用：

import turtle

screen = turtle.Screen()
# this assures that the size of the screen will always be 400x400 ...
screen.setup(500, 500)
tina = turtle.Turtle()
tina.goto(200,200)
tina.goto(-200,-200)
tina.goto(-200,200)
tina.goto(200,-200)

这是我的trinket :-)

Answer 3

import turtle
turtle.screensize(canvwidth=None, canvheight=None, bg=None)
tina = turtle.Turtle()
tina.shape('turtle')
your_name = input("What is your name")

tina.penup()
tina.forward(20)
tina.write("Why, hello there, " + your_name + "!", font=("Arial", 12, "normal"))
tina.backward(20)
tina.color("green")
tina.left(90)
tina.forward(100)
tina.right(90)
tina.goto(-65, 50)
tina.pendown()
tina.pencolor("red")
tina.forward(50)
tina.right(50)
tina.forward(50)
tina.right(100)
tina.forward(55)
tina.left(50)
tina.forward(55)
tina.penup()
tina.forward(30)
tina.pendown()
tina.dot(10)
tina.penup()
tina.goto(-100, 100)
color = input("What color is the question mark")
try:
  if color == ("red"):
    tina.write("Your are correct " + your_name + "!", font=("Arial", 20, "normal"))
    tina.backward(20)
  elif color == ("green" or "Green"):
    tina.left(90)
    tina.write("Sorry, It is actually Red", font=("Arial", 12, "normal"))
    tina.forward(100)
  elif color == ("black" or "Black"):
    tina.write("Sorry, Its is actually Red", font=("Arial", 12, "normal"))
    tina.backward(20)
  elif color == ("purple" or "Purple"):
    tina.write("Sorry, It is actually Red", font=("Arial", 12, "normal"))
    tina.backward(20)
  elif color == ("blue" or "Blue"):
    tina.write("Sorry, It is actually Red", font=("Arial", 12, "normal"))
    tina.backward(20)
except:
  tina.backward(20)
  tina.write("Sorry, but that isn't a color", font=("Arial", 12, "normal"))
  tina.backward(20)
